                       of this Annual Report on Form 10-K.



                                EXPLANATORY NOTE

We filed a Form 8-K on February 14, 2005  regarding our intention to restate our
annual  financial  statements  for the  fiscal  year  December  31,  2003.  This
amendment  on Form  10-K/A  amends our  Annual  Report on Form 10-K for the year
ended December 21, 2003 as filed with the Securities and Exchange  Commission on
March 30, 2003 and is being filed to reflect the restatement of the consolidated
financial statements.

During  the  preparation  of our 2004  year-end  financial  statements  and more
specifically the inter-company profit eliminations associated with demonstration
inventory  equipment  amounts,  Data I/O Corporation ("the Company")  identified
elimination  calculation omission errors that had resulted in the understatement
of  inter-company  expense  eliminations  on  foreign  subsidiary  demonstration
inventory  equipment  depreciation,   with  a  corresponding   overstatement  of
demonstration  inventory equipment accumulated  depreciation.  The errors, which
had  occurred  over a period  of more than five  years,  overstate  depreciation
(international   selling)  expense  associated  with   demonstration   inventory
equipment in service in the Company's foreign subsidiaries.

The errors resulted in a cumulative  overstatement  of  demonstration  inventory
equipment  accumulated   depreciation  and  a  corresponding   overstatement  of
depreciation  (international  selling) expense of approximately $112,000 through
December 31, 2004. The cumulative  impact of this error as of December 31, 2003,
including the related income tax effect, resulted in a $112,000 overstatement of
demonstration  inventory  equipment  accumulated   depreciation  reserve  and  a
$112,000  overstatement of depreciation  (international  selling)  expense.  The
income tax  effects  from the  cumulative  effect of this error had no impact on
income tax expense and just  impacted the related  disclosure  of net  operating
losses in carry forward and the related valuation allowances.

While the  Company  believes  the  impacts of these  elimination  errors are not
material to any previously issued financial  statements,  the Company determined
that the cumulative  adjustment required to correct these errors was material to
record  in  2004,  and that  the  calculation  errors  were  most  appropriately
corrected through restatement of previously issued financial  statements for the
fiscal  years  ended  December  31,  2003.  The  Company's  decision  to restate
previously  issued financial  statements was based on the impact of a cumulative
correction  on the 2004  financial  statements  rather  than the  impact  on any
previously issued financial statements.

The Company has evaluated  that the  adjustments  to the quarters other than the
fourth quarter are immaterial and the entire 2003  adjustment  will be reflected
as a correction  to the fourth  quarter of 2003 of $65,000 in the restated  Form
10-K and that accordingly no restatement is necessary for the interim  quarterly
Form 10-Q filings.

This Form 10-K/A  corrects  the  previously  issued  financial  statements.  See
Selected  Financial  Data,  Management's  Discussion  and  Analysis of Financial
Condition  and Results of  Operations,  the  Consolidated  Financial  Statements
including  Notes  to  Consolidated   Financial  Statements,   and  Controls  and
Procedures, for the impact of the restatement.

This  amendment to the Company's  Annual Report on Form 10-K for the fiscal year
ended  December 31, 2003 amends and restates only those items of the  previously
filed  Form  10-K  which  have been  affected  by the  restatement.  In order to
preserve the nature and character of the  disclosures set forth in such items as
originally filed, no attempt has been made in this amendment to modify or update
such  disclosures  except as required to reflect the effects of the  restatement
and to make non-substantive revisions to the notes to the consolidated financial
statements. For additional information regarding the restatement, see "Note 3 to
Consolidated Financial Statements" included in Part II, Item 8.

Item 1.  Business

This  Annual  Report  on Form  10-K and the  documents  incorporated  herein  by
reference  contain  forward-looking  statements  based on current  expectations,
estimates and projections about Data I/O(R) Corporation's industry, management's
beliefs and certain assumptions made by management. See "Management's Discussion
and Analysis of Financial  Condition and Results of Operations - Forward Looking
Statements."

General

Data I/O Corporation ("Data I/O") designs,  manufactures,  and sells programming
systems  used  by  designers  and  manufacturers  of  electronic  products.  Our
programming  system products are used to program  integrated  circuits ("ICs" or
"devices" or  "semiconductors")  so that the ICs will function as desired in the
customer's  electronic  product.  They are an important tool for the electronics
industry  experiencing  growing use of  programmable  ICs.  Data I/O markets and
distributes our programming  systems  worldwide,  and is a global leader in this
market. Data I/O incorporated in the State of Washington in 1969.

Data I/O  Mission.  Data  I/O's  mission  is to design  and  deliver  innovative
customer-focused  programming solutions,  which enable customers to manage their
firmware supply chain,  getting their products to market faster,  while reducing
costs in their process.  We align our products and services to make  programming
easy, delight our customers and satisfy their whole product needs.

Helping customers manage their firmware supply chain. Much of the innovation and
competitive  advantage of today's  electronic  products  comes from the software
embedded  inside the  product,  which is  commonly  referred  to as  "firmware."
Companies use firmware to differentiate  their products from their  competitors'
products, constantly writing new code to add features. This allows them to build
multiple  models with identical  hardware and many versions of firmware,  all on
one  production  line.  Any  improvement  in  production  efficiency  boosts the
profitability   of  all  products  on  that  line.   Many   original   equipment
manufacturers  ("OEMs") now outsource  production to  specialists  in electronic
manufacturing  services  ("EMS") to  maximize  the  profit  impact  from  highly
efficient  production.  The  challenges  of managing the  firmware  supply chain
remain,  however,  and can even increase  with this  additional  interface.  Our
systems  allow our  customers - both OEM and EMS  companies - to build  products
with the exact firmware  features that consumers  specify,  virtually  real-time
with the latest  software  release.  We help our customers  eliminate  inventory
risks,  delays,  rework,  and lost market  opportunities  while enabling them to
better serve their customers.

Connected  Strategy.  Data I/O's connected  strategy  leverages  network capable
products to move the customer's intellectual property seamlessly and securely up
and down the supply chain.  Our connected  strategy allows  customers to connect
engineering to manufacturing to end customers.

Business  Restructuring.  During 2003, we completed the  restructuring  process,
which began in 2001.  We took  restructuring  charges in 2001 and 2002 that were
associated with actions taken to reduce our breakeven point and realign Data I/O
with our  market  opportunities.  We  required  this  operational  repositioning
because  of the  impact of the  economic  slowdown  and the  decline  in capital
spending  across  a high  number  of  customer  groups  on  general  demand  for
programming  equipment  over the past few years.  We believe  these actions made
possible our turnaround  and  profitable  operations in 2003. At the end of 2003
our  breakeven  point was  approximately  $6.2  million  in net  sales  with 127
employees worldwide. Our breakeven point increased in 2003 primarily due to cost
increases  resulting  from the impact of the weaker  dollar on foreign  currency
based  costs  and  from  personnel  costs  due to  salary  increases,  incentive
compensation  and selective  hiring of individuals  with critical skills to help
position us as the continuing technology leader in our market.

During 2002,  we reduced our quarterly  breakeven  point from  approximately  $7
million of net sales at the beginning of 2002 to  approximately  $5.7 million at
the end of 2002. We achieved most of these  reductions by reducing our personnel
from 155 at the beginning of 2002 to 125 at the end of 2002.

During 2001, we took a number of strategic  restructuring  actions to reduce our
breakeven point. Repositioning included the following: a reduction in our global
workforce  from  224 at  the  start  of the  year  to  155 at the  end of  2001;
discontinuance or reallocation of numerous projects and activities not essential
to our  long-term  goals;  streamlining  activities  to  decrease  discretionary
marketing,  distribution  and promotional  expenses,  consolidation  of numerous
functions  across the  organization to create a team,  which was more productive
and able to respond faster to global customer  needs;  and closure of a facility
in Germany and moving its operations to other locations within Data I/O.

At December 31, 2003 all restructuring  expenses  associated with the activities
detailed above were paid and the excess restructure  accrual of $39,000 had been
reversed.

Industry Background

Data I/O operates in a niche of the electronics equipment industry that provides
programming  systems  used to load  specific  data and design  information  into
programmable devices.  Companies that design and manufacture electronic products
that  utilize  programmable  devices  purchase  these  systems  from  us.  These
companies,  our  primary  customers,  design and  manufacture  a broad  range of
electronic products for both consumer and industrial use.

Programmable  devices represent an over $10 billion segment of the semiconductor
industry, and have grown more rapidly than the semiconductor industry as a whole
in recent years. Flash memory,  NAND-Flash,  and programmable  micro-controllers
are typical of these  devices.  Programmable  devices  offer  advantages  to the
electronic  product  designer  allowing  them to bring  products  to market more
quickly and inexpensively than using  fixed-function  devices, and can offer the
advantage of simpler rapid  product  upgrades.  Programmable  devices also offer
attractive  functionality to the user of the electronic product, such as storing
personal information or customizing product  functionality.  As a result, use of
programmable  devices is growing rapidly in both high-volume consumer electronic
products and more complex electronic systems.

Due to this growth, more than 100 semiconductor manufacturers offer thousands of
different  programmable  devices. The technology trends driving the programmable
device  market  result  in  a  broad  range  of  requirements   for  programming
information  into these devices.  Programmable  memory devices  continue to have
higher   capacity  and  occupy   smaller   circuit  board  space.   Programmable
microcontroller devices are now more prevalent because semiconductor vendors are
standardizing their manufacturing  processes.  These technology advances require
advanced programming equipment like Data I/O manufactures.

Our automated  programming systems integrate  programming and handling functions
into one product for  increasing  handling  and  programming  capacity.  Quality
conscious  customers  continue  to drive  this  portion of our  business,  which
includes high-volume manufacturing and high-volume programming center customers.

Products

In order to accommodate  the expanding  variety and  quantities of  programmable
devices being  manufactured  today,  Data I/O offers multiple  solutions for the
numerous types of devices used by our customers in the various  market  segments
and  applications.  We work closely  with major  manufacturers  of  programmable
devices to develop our products to meet the requirements of a particular device.

Data I/O's line of  programming  systems  includes  a broad  range of  products,
systems,  modules, and accessories,  which we group into two general categories:
automated programming systems and non-automated  programming systems. We provide
automated  programming  systems in two  categories:  off-line  and  in-line.  In
addition,  we provide device support and service on all of our products.  Device
support is a critical aspect of our business and consists of writing  algorithms
for devices and developing socket adapters to hold and connect to the device for
programming.

Within the categories of automated and non-automated  systems,  Data I/O targets
specific solutions at specific market segments.  Data I/O optimizes the solution
based on the customer's device,  process and business needs. We think the market
growth opportunity is not a relatively costly universal solution with very broad
device  support,  but optimized  systems  focused on a narrower range of devices
(such as Flash devices), which provide customers with the economical programming
solutions  for high volumes of devices and lean  processes.  Our recent  product
introductions  have focused on these growth  markets and targeted their specific
needs.

TaskLink(R)  is our software  platform  that  provides a common  intuitive  user
interface and enhances the quality of the  customer's  programming  process.  As
part of our  core  technology,  TaskLink  also  supports  Data  I/O's  connected
strategy,  allowing  customers to connect  engineering to  manufacturing  to end
customers.

Automated Programming Systems

Data I/O  provides our  manufacturing  and  programming  center  customers  with
automated programming systems solutions that include robotic handlers, a variety
of programmers,  input and output media handling (such as tray stackers,  tubes,
loaders or  taping),  and marking  solutions.  Our  ProLINE-RoadRunner(TM)  is a
unique in-line  programming  system with  programming  speed  capability,  which
approaches the speed at which Flash devices can currently  accept data.  Many of
our  customers  need to  program  Flash  and  microcontroller  devices  in large
quantities and very quickly.  ProLINE-RoadRunner mounts directly on the assembly
machine  in  the  production  line  (Siemens,  Fuji,  Universal,  Panasonic  and
Assembleon  machines) and delivers  programmed parts from reels of blank devices
to  the  production  line  in a  just-in-time  fashion.  Our  ProLINE-RoadRunner
eliminates  production   bottlenecks  associated  with  high-density  Flash  and
microcontroller  devices,  allowing last minute firmware changes and eliminating
programmed part inventories, ultimately streamlining and reducing the customer's
production and process costs.  ProLINE-RoadRunner enables customers to implement
lean processes and is a key element in Data I/O's connected  strategy,  allowing
customers and partners to more  effectively  manage their firmware supply chain.
ProLINE-RoadRunner  currently  retails  from  $60,000 to $95,000,  depending  on
programming  capability.  We continue to leverage our  ProLINE-RoadRunner in our
platform to reach a broader market,  which during 2003 included  focusing on the
FlashCORE(TM)   architecture  by  expanding  its  capability  to  address  newer
technologies like NAND Flash support for M-Systems DiskOnChip(R) technology.

Data I/O's PS family of automated  programming  solutions offers highly flexible
solutions for off-line batch  programming.  Data I/O can configure PS systems to
support not only Flash devices,  but also a wide variety of other devices,  such
as microcontrollers.  These systems provide a number of marking,  labeling,  and
input/output options. Most importantly, customers can make changeovers extremely
fast.  This feature  allows the customer to rapidly  respond to diverse  demands
with very little downtime.  Customers can optimize the PS family systems for any
job to maximize  throughput  and, when combined with fast  changeover  times and
high  reliability,  provide the  highest  levels of output  during a  production
shift. Our latest product,  the PS288,  integrates the same FlashCORE programmer
we use in our PS300 FlashCORE, ProLINE-RoadRunner and FlashPAK(TM) and builds on
our   connected   strategy  and  common   architecture.   For  smaller   memory,
microcontroller and logic devices, our ProMaster systems offer a cost-effective,
high-yield  automated  solution.  Prices  for our  off-line  systems  range from
$50,000  to   $500,000,   with  an   average   configuration   selling   between
$200,000-$300,000.

Non-Automated Programming Systems

Our  line of  non-automated  programming  systems  provides  solutions  for both
engineering  and low to  medium-volume  manufacturing  customers.  Non-automated
programming  systems  require a user to  physically  handle  the  devices  being
programmed.  These  types of  programmers  are  also  sometimes  referred  to as
"manual" or "desktop"  programmers.  We now have three families of non-automated
programmers: Sprint, UniSystem and FlashPAK.

Engineering  customers typically use single-site  programming systems during the
prototype  phase of a new  design,  and may  purchase  inexpensive  systems  for
limited device needs or more expensive  systems to support more complex  devices
or a large variety of device types.  Single-site programming systems can perform
programming on only one programmable device at a time.

Data  I/O  offers  a range  of high  quality,  universal  single  socket  manual
programming  solutions through our UniSystem family of programming  systems. Our
UniSite and 3980 xpi  programming  systems  offer the  highest  levels of signal
integrity, which ensure the highest programming standards.  Popular in military,
aerospace,  telecommunications  and other  mission  critical  applications,  the
systems range from $11,000 to $35,000.

For more cost  constrained or higher volume  applications,  the Sprint family of
products offers excellent value for the money and  versatility.  The Sprint Quad
and  Octal  programming  systems  offer  4 and 8  socket  universal  programming
configurations  for the  higher  volume  applications.  These  two  families  of
products  range in price from under  $1,000 to $16,000 for the  multiple  socket
solutions.

Our newest  programmer,  the  FlashPAK,  leverages  the  high-speed  proprietary
FlashCORE programming  technology in the  ProLINE-RoadRunner  system. We believe
FlashPAK,  priced at $6,000,  is the world's fastest  programming  architecture,
limited today only by the speed at which Flash devices can accept data. FlashPAK
is another key element of Data I/O's connected strategy,  providing OEMs and new
product introduction facilities with a high performance Flash programming system
that can be used to validate  designs  before  moving down the  firmware  supply
chain. For manufacturing applications, the FlashPAK, a high speed, multi-socket,
small footprint desktop solution,  provides manual  programming  operations with
the highest level of flexibility at the lowest cost per part. Manufacturers that
use  manual  programming  because of lower  labor  costs in areas like Asia find
FlashPAK an attractive solution.

Data I/O  supports  and  completes  our  product  offering  with a full range of
software and device update products and worldwide service and repair capability.

Customers

Data  I/O  sells  our  products  to  customers  worldwide  in a broad  range  of
industries, including wireless handset manufacturers and other telecommunication
companies,  consumer  electronics,  computers,  test and  measurement,  medical,
transportation,  military,  aerospace,  electronic contract  manufacturing,  and
semiconductors.  Our principal  customers include Motorola,  Nokia, and Siemens.
Our  customers  either  design  and/or  manufacture   electronic  products  that
incorporate  programmable devices or provide device programming services. During
2003, we sold products to over 2,000  customers  throughout  the world,  and one
customer  accounted  for 18% of our net sales and no others  accounted  for over
10%.

Programmable  device  consumption  continues to grow as more and more electronic
product  manufacturers  take advantage of the flexibility and cost effectiveness
of programmable memory,  microcontroller and logic devices.  Electronic products
today   utilize   programmable   technology   in  one  form  or  another,   from
microcontrolled  home appliance  devices to set top boxes and wireless  devices,
which use increasingly vast amounts of memory for Internet  connectivity and new
leading  edge  features.  Therefore,  our  customers  come  from  virtually  all
industries   manufacturing   electronic  products,   and  include  the  consumer
electronic  products,  cell phone,  personal data assistants  ("PDAs") and other
wireless device manufacturers, home entertainment product sectors, aerospace and
military  applications,  the personal computer ("PC") and PC peripheral industry
and automotive electronics.

Flash memory growth.  The Flash memory customer segment is experiencing  some of
the most impressive growth of all programmable  devices.  As cell phones,  PDAs,
games  consoles,  set top boxes and other consumer  devices become more capable,
powerful  and  compact,  the demand for Flash units and  megabytes  continues to
grow.

Microcontroller  growth. As the demand for smarter electronic devices increases,
demand for greater numbers of microcontroller devices increases.  Many household
appliances today contain a microcontroller  to control the critical functions of
the  product  and provide new  features.  Examples of these  appliances  include
toasters,  refrigerators,  garage door openers and even thermostats. This growth
creates  new market  opportunities  for us and we have added  support  for these
devices   in  our   FlashCORE   architecture.   In   addition,   the  number  of
microcontrollers in automotive electronic  applications is growing rapidly, with
some cars having as many as 80 or more  microcontrollers  that control functions
from  airbag  and ABS  systems  to air  conditioning,  information  centers  and
entertainment  and communication  systems.  We are also targeting the automotive
segment as a critical and growing target segment for our solutions.

Geographic Markets and Distribution

Data I/O markets and sells our products  through a combination  of direct sales,
internal  telesales,  and indirect sales  representatives  and distributors.  We
continually  evaluate  our sales  channels  against  our  evolving  markets  and
customers.

U.S. Sales

We market our products  throughout the U.S.  using a variety of sales  channels,
including  our  own  field  sales  management   personnel,   independent   sales
representatives, and a direct telesales organization. Our U.S. independent sales
representatives  obtain orders on an agency basis,  with shipments made directly
to the customer by Data I/O. Sales of our  semiconductor  programming  equipment
products  requiring  installation  by us  that is  other  than  perfunctory  are
recorded when installation is complete,  or at the later of customer  acceptance
or  installation,  if an acceptance  clause is specified in the sales terms.  We
recognize  revenue from other product  sales at the time of shipment.  We record
revenue from the sale of service and update contracts as deferred revenue and we
recognize it on a straight-line  basis over the contractual period. Net Sales in
the  United  States  for 2003,  2002 and 2001 were  $7,263,000,  $8,347,000  and
$9,526,000, respectively.

Foreign Sales

Foreign  sales  represented  approximately  70%, 63% and 64% of net sales of our
programming systems in 2003, 2002 and 2001,  respectively (see Note 16 of "Notes
to  Consolidated  Financial  Statements").  We make  foreign  sales  through our
wholly-owned  subsidiaries  in  Germany,  China and  Canada,  as well as through
independent   distributors  and  sales  representatives   located  in  35  other
countries.   We  record  sales  made  through  foreign  subsidiaries   requiring
installation  by Data I/O that is other than  perfunctory  when  installation is
complete,  or at  the  later  of  customer  acceptance  or  installation,  if an
acceptance  clause is specified in the sales  terms.  We recognize  revenue from
other product sales at the time of shipment.  We record revenue from the sale of
service  and  update  contracts  as  deferred  revenue  and  recognize  it  on a
straight-line  basis  over  the  contractual  period.  Our  independent  foreign
distributors  purchase  Data I/O  products  in U.S.  Dollars  for  resale and we
recognize  the sale at the time of  shipment  to the  distributor.  As with U.S.
sales representatives,  sales made by international sales representatives are on
an agency basis with shipments made directly to the customer by us. We recognize
sales,   denominated  in  U.S.  Dollars,   upon  shipment,  if  installation  is
perfunctory  or does not need to be  performed  by us, or when the  equipment is
installed at the end-user's  site, if installation is more than  perfunctory and
is to be performed  by us, or in the case where  acceptance  is  required,  upon
acceptance.

Net foreign  sales for 2003,  2002 and 2001 were  $17,424,000,  $14,491,000  and
$17,300,000, respectively. We determine total foreign sales by the international
geographic area into which the products are sold and delivered,  and include not
only sales by foreign  subsidiaries  but also export  sales from the U.S. to our
foreign distributors and to our representatives' customers. Foreign sales do not
include  transfers between Data I/O and our foreign  subsidiaries.  Export sales
are subject to U.S.  Department of Commerce  regulations.  We have not, however,
experienced any difficulties to date as a result of these requirements.

Fluctuating  exchange  rates and  other  factors  beyond  our  control,  such as
international  monetary  stability,  tariff  and trade  policies,  and U.S.  and
foreign tax and economic policies, affect the level and profitability of foreign
sales. We cannot predict the effect of such factors on our business.

Competition

The  competition in the programming  systems market is highly  fragmented with a
large  number  of  smaller  organizations  offering  inexpensive  solutions.  We
estimate  that prior to the past couple  years the total  number of  programming
systems sold each year has been less than $150 million,  with Data I/O capturing
an  estimated  20 to 25% of the global  market.  Over the last three  years,  we
believe the amount has declined by about 50% and that Data I/O has gained market
share versus our significant competitors.

Competitive  factors  often  include  prices,   features,   device  support  and
programming  speed,  as the  programming  process  impacts  more  on  the  major
manufacturers'  total  production  process.  However,  competitive  factors  are
changing.  The added value for customers is becoming the whole product  solution
that fits the customer's  required  process.  As an example,  ProLINE-RoadRunner
offers a unique solution,  which best addresses the customer's  process needs in
high volume Flash  applications.  To this extent,  the value proposition of this
specific programming solution is very different from traditional solutions.

Therefore,  addressing  customers'  process needs is critical to increasing  the
opportunity for programming  solutions  beyond the current amount in this market
niche.  We estimate that customers are spending  between $1 to $2 billion a year
on  programming  memory,  microcontroller  and  logic  devices  and much of this
programming is achieved through the use of the customers' test equipment offered
by  companies  like Agilent and  Teradyne or  homegrown  solutions  for specific
markets  like  automotive.  The main  competitive  solution in the  programmable
market is,  therefore,  the in-house  solution,  and the  opportunity  exists to
substitute   customers'   solutions   with  more   economical  and  more  easily
maintainable solutions to solve the problems,  which traditional  programmers do
not address. Boundary scan tools also fall into this category,  although still a
very small market with a number of small companies participating who principally
focus on test solutions. A number of companies are part of a trend towards using
in-system  programming,  which Data I/O does not currently address but continues
to evaluate.

Manufacturing, Raw Materials, and Backlog

Data  I/O  performs  primarily  assembly  and  testing  of our  products  at our
principal  facility in Redmond,  Washington  and we outsource  our circuit board
manufacturing  and  fabrication.  We use a combination  of standard  components,
proprietary   custom  ICs  and  fabricated   parts   manufactured  to  Data  I/O
specifications.  An outside supplier located in Germany  manufactures our Sprint
non-automated  programming  systems.  Most  components used are available from a
number of different suppliers and subcontractors but certain items, such as some
handler  and  programmer   subassemblies,   custom  ICs,   hybrid  circuits  and
connectors,  are  purchased  from single  sources.  We believe  that  additional
sources  can  be  developed  for  present   single-source   components   without
significant   difficulties  in  obtaining  supplies.  We  cannot  be  sure  that
single-source  components  will always continue to be readily  available.  If we
cannot develop  alternative  sources for these  components,  or if we experience
deterioration  in  relationships  with these  suppliers,  there may be delays or
reductions in product introductions or shipments, which may materially adversely
affect our operating results.

In  accordance  with  industry  practices,  generally  all orders are subject to
cancellation prior to shipment without penalty, except for contracts calling for
custom configuration. To date, such cancellations have not had a material effect
on our sales volume. To meet customers'  delivery  requirements,  we manufacture
certain  products  based upon a combination of backlog and  anticipated  orders.
Most orders are scheduled for delivery  within 1 to 60 days after receipt of the
order.  Our  backlog of pending  orders was  approximately  $1.5  million,  $1.3
million and $1.9 million as of December 31, 2003,  2002 and 2001,  respectively.
The size of backlog  at any  particular  date is not  necessarily  a  meaningful
indicator of the trend of our business.

Research and Development

Data I/O believes  that  continued  investment  in research and  development  is
critical to our future  success.  We continue  to develop new  technologies  and
products  and enhance  existing  products.  Future  growth is to a large  extent
dependent upon the timely development and introduction of new products,  as well
as the development of algorithms to support the latest programmable  devices. We
are currently focusing our research and development  efforts on strategic growth
markets,  namely new programming  technology and automated  handling systems for
the  manufacturing  environment,  including  support  for  NAND  FLASH  and  for
M-Systems  DiskOnChip(R)  technology,  microcontroller support for FlashCORE and
additional  platforms and  improvements for  ProLINE-RoadRunner.  We continue to
also focus on increasing our capacity and  responsiveness for new device support
requests  from  customers  and  programmable  IC  manufacturers  by revising and
enhancing our internal processes and tools.  During this past year, our research
and development resulted in these new products: PS300, PS288, and the TF-30 Tray
Feeder and extensions of ProLINE-RoadRunner.

During 2003, 2002 and 2001, we made expenditures for research and development of
$4,639,000, $5,331,000 and $6,740,000,  respectively,  representing 18.8%, 23.3%
and  25.1% of net  sales,  respectively.  Research  and  development  costs  are
expensed as incurred.

Patents, Copyrights, Trademarks, and Licenses

Intellectual  property  rights  applicable to various Data I/O products  include
patents,  copyrights,  trade  secrets  and  trademarks.  Data I/O also relies on
patents,  copyrights,  trade secrets and trademarks to protect our  intellectual
property,  as well as product  development  and marketing skill to establish and
protect our market position. We also grew our patent portfolio over the past few
years as we developed  strategic  technologies like the  ProLINE-RoadRunner  and
FlashCORE that are critical to our connected strategy.

We attempt to protect our rights in  proprietary  software  products,  including
TaskLink and other software products, by retaining the title to and copyright of
the  software  and   documentation,   by   including   appropriate   contractual
restrictions  on use  and  disclosure  in our  licenses,  and by  requiring  our
employees to execute  non-disclosure  agreements.  Our software products are not
normally sold separately from sales of programming  systems.  However,  on those
occasions where software is sold separately,  revenue is recognized when a sales
agreement  exists,  when  delivery  has  occurred,  when  the  fee is  fixed  or
determinable, and when collectibility is probable.

Because of the rapidly  changing  technology  in the  semiconductor,  electronic
equipment  and  software  industries,  portions of our products  might  possibly
infringe upon existing patents or copyrights, and we may, therefore, be required
to obtain  licenses or  discontinue  the use of the  infringing  technology.  We
believe that any exposure we may have regarding possible  infringement claims is
a reasonable  business  risk  similar to that assumed by other  companies in the
electronic   equipment   and  software   industries.   However,   any  claim  of
infringement,  with or  without  merit,  could  be  costly  and a  diversion  of
management's attention,  and an adverse determination could adversely affect our
reputation,  preclude  us from  offering  certain  products,  and  subject us to
substantial liability.

Employees

As of December 31, 2003, we had 127 employees,  of which 31 were located outside
the U.S. We also utilize independent  contractors for specialty work,  primarily
in research and development, and utilize temporary workers to adjust capacity to
fluctuating  demand.  Many of our employees are highly skilled and our continued
success will depend in part upon our ability to attract and retain employees who
can  be in  great  demand  within  the  industry.  None  of  our  employees  are
represented by a collective  bargaining  unit and we believe  relations with our
employees are favorable.

Environmental Compliance

Our  facilities  are subject to numerous  laws and  regulations  concerning  the
discharge of materials or otherwise relating to the environment. Compliance with
environmental laws has not had, nor is it expected to have, a material effect on
our  capital  expenditures,   financial  position,   results  of  operations  or
competitive position.

Cautionary Factors That May Affect Future Results

Data  I/O's  disclosure  and  analysis  in  this  Annual  Report  contains  some
forward-looking  statements.  Forward-looking  statements  include  our  current
expectations  or  forecasts  of future  events.  The reader can  identify  these
statements by the fact that they do not relate strictly to historical or current
facts.  In  particular,  these  include  statements  relating to future  action,
prospective products, new technologies,  establishing foreign operations, future
performance  or results of current  and  anticipated  products,  sales  efforts,
expenses,  outsourcing  of functions,  outcome of  contingencies,  and financial
results.

Any or all of the  forward-looking  statements  in this Annual  Report or in any
other public  statement  made may turn out to be wrong.  They can be affected by
inaccurate   assumptions   we  might  make,   or  known  or  unknown  risks  and
uncertainties can affect these forward-looking  statements.  Many factors -- for
example,  product  competition  and product  development -- will be important in
determining future results.  Moreover,  neither Data I/O nor anyone else assumes
responsibility  for the  accuracy  and  completeness  of  these  forward-looking
statements. Actual future results may materially vary.

We undertake no obligation  to publicly  update any  forward-looking  statements
after the date of this Annual  Report,  whether as a result of new  information,
future events or otherwise.  The reader should not place undue  reliance on such
forward-looking  statements.  The reader is  advised,  however,  to consult  any
future  disclosures Data I/O makes on related subjects in our 10-Q, 8-K and 10-K
reports to the SEC and press  releases.  Also,  note that Data I/O  provides the
following cautionary discussion of risks,  uncertainties and possible inaccurate
assumptions  relevant to our  business.  These are  factors  that we think could
cause  Data  I/O's  actual  results  to  differ  materially  from  expected  and
historical results. Other factors besides those listed here could also adversely
affect  Data  I/O.  This  discussion  is  permitted  by the  Private  Securities
Litigation Reform Act of 1995.



RISK FACTORS

Development, Introduction and Shipment of New Products

Data I/O  currently is developing  new  engineering  and  automated  programming
systems.  Significant technological,  supplier,  manufacturing or other problems
may delay the development, introduction or production of these products.

For example, we may encounter these problems:

o technical  problems in the development of a new programming system platform or
  the robotics for new automated  handing systems

o inability to hire qualified personnel

o delays or failures to perform by third parties involved in our development
  projects

Delays in the development,  completion and shipment of new products,  or failure
of customers to accept new products, may result in a decline in sales in 2004.

Variability in Quarterly Operating Results

Data I/O's operating  results tend to vary from quarter to quarter.  Our revenue
in each quarter  substantially depends upon orders received within that quarter.
Conversely,  our  expenditures  are based on  investment  plans and estimates of
future revenues. We may, therefore,  be unable to quickly reduce our spending if
our revenues decline in a given quarter. As a result, operating results for that
quarter  will  suffer.  Our  results of  operations  for any one quarter are not
necessarily indicative of results for any future periods.

Other  factors,  which may cause our quarterly  operating  results to fluctuate,
include:

o increased competition

o timing of new product announcements

o product releases and pricing changes by us or our competitors

o market acceptance or delays in the introduction of new products

o production constraints

o labor or material shortages

o the timing of significant orders

o war or terrorism

o customers' budgets

o adverse movements in exchange rates, interest rates or tax rates

o cyclical nature of demand for our customers' products

o general economic conditions in the countries where we sell products

Due  to all of the  foregoing  factors,  it is  possible  that  in  some  future
quarters,  our  operating  results  will be below  expectations  of analysts and
investors.

Rapid Technological Change

Product technology in Data I/O's industry evolves rapidly, making timely product
innovation  essential to success in the marketplace.  Introducing  products with
improved  technologies or features may render our existing products obsolete and
unmarketable.  Technological  advances that may  negatively  impact our business
include:

o new device package types, densities, and technologies requiring hardware and
  software changes in order to be programmed by our products

o electronics equipment manufacturing practices, such as widespread use of
  in-circuit programming

o customer software platform preferences different from those on which our
  products operate

o more rigid industry standards, which would decrease the value-added element
  of our products and support services

If we cannot  develop  products  in a timely  manner  in  response  to  industry
changes,  or if our products do not perform  well,  our  business and  financial
condition will be adversely affected. Also, our new products may contain defects
or errors  that give rise to product  liability  claims  against us or cause our
products to fail to gain market  acceptance.  Our future success  depends on our
ability to successfully  compete with other  technology  firms in attracting and
retaining key technical personnel.

Economic and Market Conditions

Our business is highly  impacted by capital  spending  plans and other  economic
cycles that affect the users and  manufacturers  of ICs.  These  industries  are
highly  cyclical and are  characterized  by rapid  technological  change,  short
product  life cycles,  fluctuations  in  manufacturing  capacity and pricing and
gross margin  pressures.  As we experienced in 2003 and the past few years,  our
operations   may  in  the   future   reflect   substantial   fluctuations   from
period-to-period  as a consequence of these industry patterns,  general economic
conditions  affecting  the  timing of orders  from  major  customers,  and other
factors affecting capital spending.  These factors could have a material adverse
effect on our business and financial condition.

History of Losses

We have  incurred  net losses in two of our last  three  fiscal  years.  We will
continue  to examine our level of  operating  expense  based upon our  projected
revenues.  Any planned  increases  in  operating  expenses  may result in larger
losses in future periods if projected revenues are not achieved. As a result, we
may need to  generate  greater  revenues  than we have  recently  to achieve and
maintain  profitability.  However, we cannot provide assurance that our revenues
will increase and our strategy may not be successful resulting in future losses.

Affects of Restructuring Activities

Our  previously   implemented   restructuring   plans  may  yield  unanticipated
consequences,  such as increased burden on our administrative,  operational, and
financial resources and increased responsibilities for our management personnel.
As a result, our ability to respond to unexpected challenges may be impaired and
we may be unable to take advantage of new opportunities.

In addition,  many of the  employees  that were  terminated  possessed  specific
knowledge or expertise,  and that  knowledge or expertise may prove to have been
important to our operations.  In that case, their absence may create significant
difficulties,  particularly if our business experiences  significant growth. Any
failure by us to properly manage this rapid change in workforce could impair our
ability to efficiently  manage our business,  to maintain and develop  important
relationships with third-parties,  and to attract and retain customers. It could
also cause us to incur higher operating costs and delays in the execution of our
business plan or in the reporting or tracking of our financial results.

Need for Additional Funding

Our  past  revenues  have  been  and our  future  revenues  may  continue  to be
insufficient  to support the expense of our  operations and any expansion of our
business. We may therefore need additional equity or debt capital to finance our
operations.  If we are unable to generate  sufficient cash flows from operations
or to obtain funds through  additional debt or equity financing,  we may have to
reduce some or all of our development and sales and marketing  efforts and limit
the expansion of our business.

We believe our existing cash and cash equivalents will be sufficient to meet our
working capital  requirements  for at least the next twelve months.  Thereafter,
depending on the  development of our business,  we may need to raise  additional
cash for working capital or other expenses. We may also encounter  opportunities
for  acquisitions or other business  initiatives  that require  significant cash
commitments,  or  unanticipated  problems  or  expenses  that could  result in a
requirement for additional cash before that time.

Therefore,  we may seek  additional  funding  through  public or private debt or
equity  financing or from other sources.  We have no commitments  for additional
financing,  and we may experience  difficulty in obtaining  funding on favorable
terms,  if at all. Any financing we obtain may contain  covenants  that restrict
our freedom to operate our business or may require us to issue  securities  that
have  rights,  preferences  or  privileges  senior to Data  I/O's  Common  Stock
("Common Stock") and may dilute your ownership interest.

Competition

Technological  advances have reduced the barriers of entry into the  programming
systems  markets.  We expect  competition to increase from both  established and
emerging  companies.  If we fail to compete  successfully  against  current  and
future sources of competition,  our profitability and financial performance will
be adversely impacted.

Dependence on IC Manufacturers

We work  closely  with  most  semiconductor  manufacturers  to  ensure  that our
programming   systems  comply  with  their  requirements.   In  addition,   many
semiconductor  manufacturers  recommend our programming systems for use by users
of their programmable devices. These working relationships enable us to keep our
programming systems product line up to date and provide end-users with broad and
current  programmable device support.  Our business may be adversely affected if
our relationships with semiconductor manufactures deteriorate.

Dependence on Suppliers

Certain parts used in our products are currently  available from either a single
supplier or from a limited number of suppliers. If we cannot develop alternative
sources of these components,  if sales of parts are discontinued by the supplier
or we experience  deterioration in our relationship with these suppliers,  there
may be delays or reductions  in product  introductions  or shipments,  which may
materially adversely affect our operating results.

Because we rely on a small number of suppliers for certain parts, we are subject
to  possible  price  increases  by these  suppliers.  Also,  we may be unable to
accurately forecast our production schedule. If we under estimate our production
schedule,  suppliers may be unable to meet our demand for components. This delay
in the supply of key components may  materially  adversely  affect our business.
Over  estimation  of  demand  will lead to excess  inventories  that may  become
obsolete.

The non-automated  programming  system products we acquired when we acquired SMS
in  November  1998  are  currently  manufactured  to  our  specifications  by  a
third-party  foreign  contract  manufacturer.  We may not be able  to  obtain  a
sufficient  quantity of these  products if and when needed,  which may result in
lost sales.

Reliance on Third-Party Distribution Channels

Data  I/O  has  an   internal   sales  force  and  also   utilizes   third-party
representatives,  and distributors.  Therefore, the financial stability of these
distributors is important. Highly skilled professional engineers use most of our
products.  To be effective,  third-party  distributors must possess  significant
technical,  marketing  and sales  resources  and must devote their  resources to
sales  efforts,  customer  education,   training  and  support.  These  required
qualities limit the number of potential third-party  distributors.  Our business
will suffer if we cannot  attract and retain a  sufficient  number of  qualified
third-party distributors to market our products.

International Operations

International sales represented 70% of our net revenue for the fiscal year ended
December  31, 2003.  We expect that  international  sales will  continue to be a
significant  portion of our net revenue.  International sales and operations may
fluctuate due to various factors, including:

o migration of manufacturing to low cost geographies

o regulatory requirements and any changes to these requirements

o tariffs and taxes

o difficulties in staffing and managing foreign operations

o longer average payment cycles and difficulty in collecting accounts receivable

o fluctuations in foreign currency exchange rates

o impact of the Euro

o compliance with applicable export licensing requirements

o product safety and other certification requirements

o difficulties in integrating foreign and outsourced operations

o political and economic instability

The European  Community and European  Free Trade  Association  have  established
certain electronic emission and product safety requirements ("CE"). Although our
products  currently  meet  these  requirements,  failure  to obtain  either a CE
certification  or a waiver for any product may  prevent us from  marketing  that
product in Europe.

We operate subsidiaries in Germany, China and Canada. Our business and financial
condition  is  sensitive to currency  exchange  rates or any other  restrictions
imposed on their currencies. Currency exchange fluctuations in Canada, China and
Germany may adversely affect our investment in our subsidiaries.

Protection of Intellectual Property

Refer to the section  "Patents,  Copyrights,  Trademarks and Licenses" in Item 1
above.

Acquisitions

We may pursue  acquisitions  of  complementary  technologies,  product  lines or
businesses. Future acquisitions may include risks, such as:

o burdening management and our operating teams during the integration of the
  acquired entity

o diverting management's attention from other business concerns

o failing to successfully integrate the acquired products

o lack of acceptance of the acquired products by our sales channels or customers

o entering markets where we have no or limited prior experience

o potential loss of key employees of the acquired company

o additional burden of support for an acquired programmer architecture

Future acquisitions may also impact Data I/O's financial position.  For example,
we may use significant  cash or incur  additional  debt,  which would weaken our
balance sheet. We may also capitalize  goodwill and intangible  assets acquired,
the impairment of which would reduce our profitability. We cannot guarantee that
future acquisitions will improve our business or operating results.

Dependence on Key Personnel

Refer to the section "Employees" above.

Potential Volatility of Stock Price

The stock prices of technology  companies  tend to fluctuate  significantly.  We
believe factors such as  announcements  of new products by us or our competitors
and quarterly variations in financial results may cause the market price of Data
I/O's Common Stock to fluctuate substantially.  In addition,  overall volatility
in the stock market,  particularly in the technology  company  sector,  is often
unrelated  to  the  operating   performance   of  companies.   If  these  market
fluctuations continue in the future, they may adversely affect the price of Data
I/O's Common Stock.

Item 2.  Properties

In May 1997, Data I/O completed the sale of the land and building comprising our
Redmond,  Washington  corporate  headquarters  and it is  currently  leasing the
96,000 square foot building on a 10-year  leaseback  agreement with an option to
renew the lease for an  additional  10 years.  This lease  required  base annual
rental  payments in 2003 of  approximately  $1,138,000.  See Note 7 of "Notes to
Consolidated  Financial  Statements."  As part of our  1999  restructuring  plan
implementation,   we  vacated   one  floor  of  the  leased   Redmond   facility
(approximately  25,000  square feet) and sublet the majority of this space for a
period  of 28 months  beginning  January  1,  2000,  at a rate of  approximately
$33,000 per month through April 2002.  The sublease  terminated in June 2002. We
have not been  successful  in  subleasing  this space and believe the market for
this space is currently quite limited.

In addition to the Redmond facility,  approximately  9,000 square feet is leased
at five  foreign  locations,  including  our Canadian  sales and service  office
located  in  Mississauga,   Ontario,   German  sales,  service  and  engineering
operations  located in Munich,  Germany,  and three sales and service offices in

Item 6.  Selected Financial Data

During 2004, Data I/O identified  elimination  calculation  omission errors that
had resulted in the  understatement  of  inter-company  expense  eliminations on
foreign  subsidiary  demonstration  inventory  equipment  depreciation,  with  a
corresponding  overstatement of demonstration  inventory  equipment  accumulated
depreciation at December 31, 2004. The errors,  which had occurred over a period
of more than five years, overstated depreciation (international selling) expense
associated with  demonstration  inventory  equipment in service in the Company's
foreign subsidiaries. Because the cumulative impact of this error as of December
31,  2003  resulted  in  a  $112,000  error,  the  Company's  previously  issued
consolidated financial statement for the year ended December 31, 2003, 2002, and
2001 have been restated.

The following selected consolidated  financial data has been restated and should
be read in conjunction with the consolidated  financial statements and the notes
thereto and the information contained herein in Item 7, "Management's Discussion
and Analysis of Financial  Condition and Results of  Operations."  See Note 3 to
the consolidated financial statement for further discussion of this matter.

Data I/O adopted SEC Staff Accounting  Bulletin No. 101, Revenue  Recognition in
Financial  Statements  (SAB 101) in the  fourth  quarter  of fiscal  year  2000,
effective  beginning  of the first  quarter of fiscal  year 2000.  The pro forma
information  in the table below  reflects  the  adoption of SAB 101.  Historical
results are not necessarily indicative of future results.

Item 7.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations

FORWARD-LOOKING STATEMENTS

Management's  Discussion  and  Analysis of Financial  Conditions  and Results of
Operations  presented  below  reflect  certain  restatements to  our  previously
reported operating results for the year ended December 31, 2003.

During 2004, the Company  identified certain errors related to the inter-company
profit eliminations  associated with demonstration  inventory equipment amounts.
Because  the errors  resulted in a  cumulative  overstatement  of  demonstration
inventory equipment accumulated  depreciation and a corresponding  overstatement
of depreciation (international selling) expense, the Company's previously issued
consolidated financial statements for the year ended December 31, 2003 have been
restated.  The  Selling,   General  and  Administrative  expenses  discussed  in
Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations have been adjusted to reflect the restated numbers. See Note 3 to the
consolidated financial statement for further discussion of this mater.

This Annual Report on Form 10-K includes  forward-looking  statements within the
meaning  of the  Private  Securities  Litigation  Reform  Act of 1995.  This Act
provides a "safe harbor" for  forward-looking  statements to encourage companies
to provide  prospective  information  about  themselves as long as they identify
these statements as forward-looking and provide meaningful cautionary statements
identifying important factors that could cause actual results to differ from the
projected results.  All statements other than statements of historical fact made
in  this  Annual  Report  on  Form  10-K  are  forward-looking.  In  particular,
statements  herein regarding  industry  prospects and trends;  future results of
operations  or  financial   position;   integration  of  acquired  products  and
operations;  market  acceptance of our newly  introduced  or upgraded  products;
development,  introduction  and shipment of new products;  establishing  foreign
operations;  and any  other  guidance  on  future  periods  are  forward-looking
statements. Forward-looking statements reflect management's current expectations
and are inherently  uncertain.  Although Data I/O believes that the expectations
reflected  in  these  forward-looking   statements  are  reasonable,  we  cannot
guarantee  future results,  levels of activity,  performance,  achievements,  or
other  future  events.  Moreover,  neither  Data  I/O nor  anyone  else  assumes
responsibility  for the  accuracy  and  completeness  of  these  forward-looking
statements.  Data I/O is under no duty to  update  any of these  forward-looking
statements  after the date of this Annual  Report.  The Reader  should not place
undue reliance on these  forward-looking  statements.  The following discussions
and the section entitled  "Business - Cautionary  Factors That May Affect Future
Results"  describes  some,  but not all, of the  factors  that could cause these
differences.

OVERVIEW

In 2003,  our  primary  goal was to manage the  business  to achieve  profitable
operations,  while  developing  and  enhancing  products  to drive  revenue  and
earnings growth.  Our challenge  continued to be the weak and uncertain economic
environment with its limited capacity related demand and weak capital  spending.
We expect that demand for capacity should improve, based on forecasted increased
unit  sales  for the  semiconductor  industry,  which  should  provide  improved
business opportunities for Data I/O.

The restructuring actions that were initiated in 2001 and continued in 2002 were
completed in 2003.  This brought our  quarterly  breakeven  point down below the
level  of net  sales  that  we  were  experiencing  in  2003,  resulting  in our
turnaround  and  profitability.   We  are  continuing  our  efforts  to  balance
increasing  costs and  strategic  investments  in our business with the level of
demand and mix of business we expect.

We are focusing our research and  development  efforts in our  strategic  growth
markets, namely new programming technology and automated programming systems for
the  manufacturing  environment,  particularly  extending the  capabilities  and
support  for  our  FlashCORE  architecture  and  the  ProLINE-RoadRunner  and PS
families.  To better  support our customers in their  geographic  areas and time
zones, we have expanded  device support  operations in Germany and India and are
in the process of setting up a new device support center in Shanghai, China.

Our  customer  focus  has  been  on  strategic  high  volume  manufacturers  and
programming  centers and the  combination  of our newer  products  with the NAND
Flash and  microcontroller  support  to gain new  accounts  and  break  into new
markets,  such as  microcontrollers  for the  automotive  market.  We are in the
process of setting up a new subsidiary in China,  expanding our China operations
to take advantage of the growth of manufacturing in China. We also increased our
efforts in 2003 to partner with the semiconductor  manufacturers to better serve
our mutual customers.

BUSINESS RESTRUCTURING PROGRESS

During  2003,  we completed  the  restructuring  that began  during 2001,  which
included  actions taken to reduce our breakeven  point and realign Data I/O with
our market opportunities.  We required this operational repositioning because of
the impact of the economic slowdown and the decline in capital spending across a
high number of customer groups on general demand for programming  equipment over
the past few  years.  At the end of 2003,  our  quarterly  breakeven  point  was
approximately  $6.2  million  in net sales  with 127  employees  worldwide.  Our
breakeven  point  increased in 2003,  primarily due to cost increases  resulting
from the impact of the weaker  dollar on foreign  currency  based costs and from
personnel costs due to salary  increases,  incentive  compensation and selective
hiring of individuals with critical skills to help position us as the continuing
technology leader in our market.

During 2002, we recorded  restructuring  charges of $632,000 in connection  with
our  actions to reduce our  quarterly  breakeven  point  from  approximately  $7
million of net sales at the beginning of 2002 to  approximately  $5.7 million at
the end of 2002. We achieved most of these  reductions by reducing our personnel
from 155 at the beginning of 2002 to 125 at the end of 2002.

During 2001, we recorded  restructuring charges of $1,211,000 in connection with
a number of strategic  restructuring actions to reduce our breakeven point. This
restructuring  included the following:  a reduction in our global workforce from
224 at the  start  of the  year to 155 at the  end of  2001;  discontinuance  or
reallocation of numerous  projects and activities not essential to our long-term
goals; streamlining activities to decrease discretionary marketing, distribution
and  promotional  expenses,  consolidation  of  numerous  functions  across  the
organization  to create a team,  which was more  productive  and able to respond
faster to global customer needs; and closure of a facility in Germany and moving
our operations to other locations within Data I/O.

At December 31, 2003 all restructuring  expenses  associated with the activities
detailed  above had been paid and the excess  expense  accrual  of  $39,000  was
reversed during 2003.

CRITICAL ACCOUNTING POLICY JUDGMENTS AND ESTIMATES

The preparation of financial statements in accordance with accounting principles
generally  accepted  in the  United  States  of  America  requires  that we make
estimates  and  judgments,   which  affect  the  reported   amounts  of  assets,
liabilities, revenues and expenses, and related disclosures of contingent assets
and  liabilities.  On an  on-going  basis,  Data I/O  evaluates  our  estimates,
including those related to sales returns, bad debts,  inventories,  investments,
intangible assets, income taxes, warranty  obligations,  restructuring  charges,
contingencies such as litigation, and contract terms that have multiple elements
and other complexities typical in the telecommunications  equipment industry. We
base our  estimates  on  historical  experience  and other  assumptions  that we
believe are reasonable under the  circumstances.  Actual results may differ from
these estimates under different assumptions or conditions.

Data I/O believes the following  critical  accounting  policies  affect the more
significant  judgments and estimates  used in the  preparation  of our financial
statements:

Revenue Recognition:  Sales of our semiconductor  programming equipment products
requiring  installation  by us that is other than  perfunctory are recorded when
installation   is  complete,   or  at  the  later  of  customer   acceptance  or
installation,  if an  acceptance  clause is  specified  in the sales  terms.  We
recognize  revenue from other product  sales at the time of shipment.  We record
revenue from the sale of service and update contracts as deferred revenue and we
recognize it on a  straight-line  basis over the  contractual  period,  which is
typically one year. We establish a reserve for sales returns based on historical
trends in product  returns and  estimates  for new items.  If the actual  future
returns differ from historical levels, our revenue could be adversely affected.

Allowance for Doubtful  Accounts:  We base the  allowance for doubtful  accounts
receivable on our assessment of the collectibility of specific customer accounts
and the aging of accounts  receivable.  If there is a  deterioration  of a major
customer's  credit  worthiness  or actual  defaults  are higher than  historical
experience,  our  estimates  of the  recoverability  of amounts  due us could be
adversely affected.

Inventory  Provisions:  We base inventory  purchases and commitments upon future
demand  forecasts  and historic  usage.  If there is a  significant  decrease in
demand for our  products  or there is a higher  risk of  inventory  obsolescence
because of rapidly changing technology and customer  requirements,  Data I/O may
be required to increase our inventory provision adjustments and our gross margin
could be adversely affected.

Warranty  Accruals:  Data I/O accrues for  warranty  costs based on the expected
material and labor costs to fulfill our warranty  obligations.  If we experience
an increase in warranty claims, which are higher than our historical experience,
our gross margin could be adversely affected.

-----------------------------------------------------------------------------------------------------------------------------


2003 vs. 2002
Data I/O  experienced  a turnaround  in sales during 2003,  with a resurgence in
sales of automated system products. In particular, automated systems aftermarket
products  and PS300  FlashCORE  and related  upgrades,  which  were new in 2003,
drove the sales growth. Our non-automated systems continued a trend of declining
sales in older products;  however, FlashPAK, which was new in 2002, grew 292% in
2003, partially  offsetting the decline.  Also contributing to the non-automated
system decline was the loss of a low cost programmer  line. ICE Technology,  our
former supplier of the line, ceased business.  In 2003, sales related to the Ice
Technology products were approximately $50,000, compared to $250,000 in 2002.

International sales grew, particularly in Europe, while sales in the U.S. market
continued to decline.  The U.S.  dollar  continued  to weaken in 2003,  which we
believe  assisted our export  sales,  due to  increased  buying power of foreign
currencies  and  the  favorable   effect  of  currency   translation  for  sales
denominated in foreign currency, and in particular the Euro. We see a continuing
trend in migration  of customers  moving  manufacturing  operations  to low-cost
geographies,  thereby increasing international sales opportunities. The weakened
U.S. dollar,  especially compared to the Euro, is expected to continue to assist
our export sales.

We are continuing the transition to a common programming architecture for all of
our products.  This allows us to consolidate device support on a single platform
and provides  substantial cost benefits to Data I/O. The recently  introduced 
PS288   FlashCORE   automated   programming   system   incorporates  this common
architecture.  In 2003,  we also  introduced  NAND and  microcontroller  support
FlashCORE  architecture,  the TF-30  Tray  Feeder  System,  and a version of our
ProLINE-RoadRunner  designed for Panasonic machines. We expect these products to
increase our revenues;  however, partially offsetting this increase is the trend
of declining sales of our older product lines.

2002 vs. 2001
Data I/O sales  declined for the year 2002  compared to 2001.  However,  for the
third and fourth  quarters of 2002,  sales  increased  over the same quarters in
2001.  We attribute  the overall  decline to the  continued  economic  downturn,
especially in capital spending.  Sales declined in all product  categories,  but
the declines were offset in part by increased sales from our  ProLINE-RoadRunner
and  new  FlashPAK  product  lines.  Sales  declined  in  both  in  the  US  and
international markets with the Americas and Europe declining the most.

-----------------------------------------------------------------------------------------------------------------------------


2003 vs. 2002
Gross  margins  increased in both dollars and as a percentage  of sales for 2003
compared  to 2002.  The  increase  in gross  margin  dollars was due to both the
increase in revenue dollars as well as the savings related to our  restructuring
actions.  The  restructuring  efforts  lowered  our  annual  breakeven  point by
implementing  cost  reductions  as well as lowering  inventory  reserve  charges
compared  to 2002.  The  continued  product  mix  shift  towards  higher  margin
automated systems aftermarket continued to be a favorable factor in 2003.

2002 vs. 2001
Gross margin  decreased in dollars due primarily to the decline in sales volume.
Gross margin  increased as a percentage  of sales  primarily  due to the savings
from the restructuring and  implementation of cost reductions,  as well as lower
inventory  reserve and  warranty  charges.  The  product mix towards  additional
ProLINE-RoadRunner  and related  aftermarket  products  also  improved the gross
margin as a percentage of sales. The restructuring efforts lowered our breakeven
point  by  bringing  cost  and  operation   expenditures,   primarily  personnel
reductions, in line with the revenue levels we experienced at the end of 2002.

-----------------------------------------------------------------------------------------------------------------------------


2003 vs. 2002
Research and development  ("R&D") spending for 2003 as compared to 2002 declined
both in  dollars  and as a  percentage  of  sales.  This  was  again  due to the
restructuring  actions,  primarily personnel reductions and cost control efforts
taken  over the past two  years.  During  2003,  Data  I/O's R&D  focused on the
FlashCORE  architecture,  expanding its capability to address newer technologies
like  NAND  Flash  support  for  M-Systems  DiskOnChip  technology  as  well  as
microcontroller  device  support.  New  products  in the PS family of  automated
systems  included  the PS300  FlashCORE,  the  TF-30  Tray  Feeder  system  and,
introduced  in  early  2004,  the  PS288   FlashCORE.    Also,  we  released  a
ProLINE-RoadRunner version for Panasonic machines.

2002 vs. 2001
R&D  spending  for 2002 as  compared to 2001  declined  both in dollars and as a
percentage of sales.  This was due primarily to the lower  headcount  related to
our  restructuring  actions  during 2001 and 2002.  During 2002,  Data I/O's R&D
focused  on the  new  FlashPAK  gang  programming  system  and  PS300  FlashCORE
automated  programming  system,  which  integrated the programming  architecture
first introduced in the  ProLINE-RoadRunner.  We also released the following new
products: ProLINE Infinity, a ProLINE-RoadRunner utilizing an automated handler;
ProLINE-RoadRunner Variable Capacity Options; TF-20 Tray Feeder System; and High
Insertion Socket Adapters.

We  believe  it is  essential  to invest  in R&D to  significantly  enhance  our
existing products and to create new products as markets develop and technologies
change. We are focusing our R&D efforts in our strategic growth markets,  namely
new   programming   technology  and  automated   programming   systems  for  the
manufacturing  environment,  particularly extending the capabilities and support
for our FlashCORE architecture and the ProLINE-RoadRunner. In 2004, we expect to
add personnel and project related costs, so R&D spending is expected to increase
in 2004.

----------------------------------------------------------------------------------------------------------------------------


2003 vs. 2002
Selling,  General and Administrative  ("SG&A") expenses decreased by $539,000 in
2003  versus the prior  year due  primarily  to the  restructuring  actions  and
reduced marketing expenses. Partially offsetting this decrease was our increased
facility  costs due to  increased  rent and loss of a  sub-tenant;  profit-based
bonuses; and increased selling costs due to currency translation with the weaker
US dollar and commissions.

2002 vs. 2001
SG&A  spending  decreased  by $1.5  million  in 2002  versus  the prior year due
primarily to the restructuring  actions.  We reduced our expense by lowering our
bad debts  reserve due to  collection  of accounts  receivable,  incurring  less
retirement  plan  costs  and  lower  commissions,   partially  offsetting  these
reductions were higher rent and insurance costs.

----------------------------------------------------------------------------------------------------------------------------


2003 vs. 2001
Interest  income for 2003  increased  as compared to 2002  primarily  due to the
increase in cash, cash equivalents and marketable securities.

2002 vs. 2001
Interest  income for 2002  decreased  as compared to 2001  primarily  due to the
reduction in interest rates that occurred during 2002 and 2001.

----------------------------------------------------------------------------------------------------------------------------


2003 vs. 2002 and 2002 vs. 2001
Income tax expense in all years relates to foreign  income taxes.  For financial
reporting  purposes,  Data I/O  established tax valuation  reserves  against our
deferred tax assets because of the  uncertainty  relating to the  realization of
such asset values.  We had valuation  allowances of $9.7 million,  $10.1 million
and $9.0 million at December 31, 2003, 2002 and 2001, respectively.

INFLATION AND CHANGES IN FOREIGN CURRENCY EXCHANGE RATES

Sales and  expenses  incurred by foreign  subsidiaries  are  denominated  in the
subsidiary's  local currency and translated  into U.S. Dollar amounts at average
rates of exchange during the year. We recognized  foreign  currency  transaction
losses of $81,000,  $150,000 and $222,000 in 2003, 2002 and 2001,  respectively.
The transaction losses resulted primarily from sales by our German subsidiary to
our main  customers,  which were  invoiced in US  dollars.  We hedge our foreign
currency  exposure  on sales  of  inventory  and  certain  loans to our  foreign
subsidiaries through the use of foreign exchange contracts. See Note 1 of "Notes
to Consolidated Financial Statements."

----------------------------------------------------------------------------------------------------------------------------


In 2003,  cash and  marketable  securities  increased by  $1,275,000,  primarily
resulting from funds  generated by operations.  Key elements of working  capital
changes reflected the increase in business:  inventories  increased by $131,000;
accounts  receivable  increased  by $726,000;  and accounts  payable and accrued
expenses together increased  $274,000.  The increase in accounts receivable also
reflects the longer  collection period typically  associated with  international
sales.

We estimate that capital  expenditures for property,  plant and equipment during
2004 are planned to be approximately  $700,000.  Although we expect to make such
expenditures, we had no significant outstanding purchase commitments at December
31, 2003. Such expenditures are expected to be funded by existing and internally
generated funds or lease financing.

As a result  of our  significant  product  development,  customer  support,  and
selling and marketing efforts, Data I/O has required substantial working capital
to fund our operations.  Over the last few years, we restructured our operations
to lower our costs and  operating  expenditures  to lower our  breakeven  point,
preserve our cash position and return to profitable operations,  as reflected in
our 2003 results.  We believe that we have sufficient  working capital available
under our operating plan to fund our operations and capital requirements through
at least  December 31, 2004.  Any  substantial  inability to achieve our current
business plan could have a material  adverse  impact on our financial  position,
liquidity,  or results of operations  and may require us to reduce  expenditures
and/or seek additional financing.

Aggregate Contractual Obligations and Commitments

Data I/O has purchase  obligations for inventory and production costs as well as
other obligations such as capital  expenditures,  service contracts,  marketing,
and development agreements.  Arrangements are considered purchase obligations if
a  contract  specifies  all  significant  terms,   including  fixed  or  minimum
quantities to be purchased,  a pricing  structure and approximate  timing of the
transaction. Most arrangements are cancelable without a significant penalty, and
with short notice,  typically  less than 90 days.  Any amounts  reflected on the

SHARE REPURCHASE PROGRAM

Under a previously announced share repurchase program, Data I/O is authorized to
repurchase  up to  1,123,800  shares of our  outstanding  Common  Stock.  We may
execute  these  purchases  through open market  purchases at  prevailing  market
prices, through block purchases or in privately negotiated transactions,  and we
may commence or discontinue  at any time. As of December 31, 2003,  Data I/O has
repurchased  1,016,200  shares under this repurchase  program at a total cost of
approximately $7.1 million.  Data I/O has not repurchased shares under this plan
since the second quarter of 1997, although it still has the authority to do so.

NEW ACCOUNTING PRONOUNCEMENTS

During 2001, the Financial Accounting Standards Board (FASB) issued Statement of
Financial  Accounting  Standards (SFAS) No. 143 "Accounting for Asset Retirement
Obligations"  and,  during 2002, the FASB issued SFAS No. 146,  "Accounting  for
Costs Associated with Exit and Disposal  Activities".  The adoption of SFAS Nos.
143  and  146  during  fiscal  2003  did  not  have  a  material  impact  on our
consolidated financial statements.

In November  2002,  the  Emerging  Issues Task Force (EITF)  released  Issue No.
02-16,   "Accounting   by  a  Customer   (including  a  Reseller)   for  Certain
Consideration  Received from a Vendor",  applicable to Data I/O for arrangements
entered into beginning in fiscal 2003.  Data I/O records  vendor  allowances and
discounts in the income  statement  when the purpose for which those monies were
designated is fulfilled.  As such,  the adoption of EITF No. 02-16 during fiscal
2003 did not have a material impact on our consolidated financial statements.

In November 2002, the Emerging Issues Task Force reached a consensus  opinion on
EITF 00-21,  "Revenue  Arrangements with Multiple  Deliverables."  The consensus
provides that revenue arrangements with multiple  deliverables should be divided
into separate units of accounting if certain criteria are met. The consideration
for the  arrangement  should be allocated to the  separate  units of  accounting
based on their relative fair values, with different provisions if the fair value
of all deliverables are not known or if the fair value is contingent on delivery
of specified items or performance  conditions.  Applicable  revenue  recognition
criteria  should be considered  separately for each separate unit of accounting.
EITF 00-21 is effective for revenue  arrangements entered into in fiscal periods
beginning  after  June 15,  2003.  Entities  may elect to report the change as a
cumulative  effect  adjustment  in  accordance  with APB Opinion 20,  Accounting
Changes. Data I/O has adopted the provisions of the statement,  which has had no
material impact.

In January 2003, the FASB issued  Interpretation 46,  "Consolidation of Variable
Interest  Entities"  (FIN  46).  FIN 46  interprets  ARB No.  51,  "Consolidated
Financial  Statements," as amended by FASB Statement No. 94,  "Consolidation  of
All Majority-Owned Subsidiaries," which requires the preparation of consolidated
financial  statements when one entity has a controlling  financial interest in a
second  entity.  FIN 46 specifies  disclosures  that are required for  financial
statements  issued after January 31, 2003 but prior to the effective date of the
Interpretation  for entities  created  before  February 1, 2003 and interests in
those entities  acquired  before that date, as well as disclosures  that will be
required  for  financial  statements  of primary  beneficiaries  and others with
variable  interests in variable  interest  entities  issued after the  effective
date. The FASB has published a revision to  Interpretation 46 to clarify some of
the provisions of FIN 46 and to exempt certain entities from its provisions. The
adoption of this interpretation did not have a material impact on our results of
operations or financial position, as we do not have variable interest entities.

In April 2003, the FASB issued Statement No. 149, "Amendment of Statement 133 on
Derivative  Instruments  and  Hedging  Activities."  The  Statement  amends  and
clarifies  accounting for derivative  instruments,  including certain derivative
instruments  embedded  in other  contracts,  and for  hedging  activities  under
Statement 133. Data I/O has adopted the  provisions of the statement,  which has
had no material impact.

In May  2003,  the FASB  issued  Statement  No.  150,  "Accounting  for  Certain
Financial  Instruments with Characteristics of both Liabilities and Equity." The
statement  requires that certain  financial  instruments,  which under  previous
guidance were accounted for as equity, must now be accounted for as liabilities.
This  statement  is  effective  for all  financial  instruments  entered into or
modified after May 31, 2003." The adoption of SFAS No 150 during fiscal 2003 did
not have a material impact on our consolidated financial statements.

Item 7A.  Quantitative and Qualitative Disclosure About Market Risk

With respect to our foreign  currency  exchange rate risk, we currently use only
foreign currency hedge derivative  instruments,  which, at a given date, are not
material.  However,  Data I/O is exposed to interest  rate risks.  We  generally
invest in high-grade  commercial  paper with original  maturity  dates of twelve
months or less and  conservative  money market funds to minimize our exposure to
interest  rate  risk on our  marketable  securities,  which  are  classified  as
available-for-sale  as of December 31, 2003 and  December  31, 2002.  We believe
that the market risk arising from holdings of these financial instruments is not
material.

principal  cash  flows  and the  related  weighted  average  interest  rates (in
thousands):

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

--------------------------------------------------------------------------------

To the Board of Directors and Stockholders
Data I/O Corporation

We have  audited  the  accompanying  consolidated  balance  sheets  of Data  I/O
Corporation  as of December  31,  2003,  and 2002 and the  related  consolidated
statements of operations,  stockholders'  equity, and cash flows for each of the
three years in the period ended December 31, 2003.  These  financial  statements
are the  responsibility of the Company's  management.  Our  responsibility is to
express  an  opinion  on  these  financial  statements  based on our  audits.

We conducted our audits in accordance  with the standards of the Public  Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements  are free of material  misstatement.  The Company is not  required to
have,  nor were we  engaged to perform  an audit of its  internal  control  over
financial reporting.  Our audit included  consideration of internal control over
financial  reporting  as  a  basis  for  designing  audit  procedures  that  are
appropriate  in the  circumstances,  but not for the  purpose of  expressing  an
opinion on the  effectiveness  of the Company's  internal control over financial
reporting.  Accordingly,  we express  no such  opinion.  An audit also  includes
examining,  on a test basis,  evidence supporting the amounts and disclosures in
the  financial   statements,   assessing  the  accounting  principles  used  and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.  We   believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the financial  position of Data I/O  Corporation  as of
December 31, 2003 and 2002, and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 2003, in conformity
with accounting principles generally accepted in the United States of America.

As discussed in Note 3, the Company's  consolidated  financial  statements as of
and for the year ended December 31, 2003 have been restated.

Our audits  were  conducted  for the  purpose of forming an opinion on the basic
financial  statements  taken as a whole.  The  financial  statement  schedule as
Schedule II is  presented  for  purposes  of  additional  analysis  and is not a
required  part  of the  basic  financial  statements.  This  schedule  has  been
subjected to the auditing procedures applied in the audit of the basic financial
statements  and, in our opinion,  is fairly  stated in all material  respects in
relation to the basic financial statements taken as a whole.

statements, amounts that are based on estimates and judgments, which it believes
are reasonable under the circumstances.

                              DATA I/O CORPORATION

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations

Data I/O Corporation ("Data I/O") designs,  manufactures,  and sells programming
systems  used  by  designers  and  manufacturers  of  electronic  products.  Our
programming  system products are used to program  integrated  circuits ("ICs" or
"devices" or  "semiconductors")  with the specific unique data necessary for the
ICs contained in various products, and are an important tool for the electronics
industry  experiencing  growing  use of  programmable  ICs.  Customers  for  our
programming  system  products  are located  around the world,  primarily  in the
United  States,  Europe  and the Far  East.  Our  manufacturing  operations  are
currently  located in the United States.  An outside supplier located in Germany
currently manufactures our Sprint non-automated programming system.

As a result  of our  significant  product  development,  customer  support,  and
selling and marketing efforts in a period of weak capital spending, Data I/O has
required substantial working capital to fund our operations.  We believe that we
have sufficient  working capital  available under our operating plan to fund our
operations  and capital  requirements  through at least  December 31, 2004.  Any
substantial inability to achieve the current business plan could have a material
adverse impact on our financial position, liquidity, or result of operations and
may require us to reduce expenditures and/or seek additional financing.

Principles of Consolidation

The  consolidated   financial  statements  include  the  accounts  of  Data  I/O
Corporation and our  wholly-owned  subsidiaries.  All  significant  intercompany
accounts and transactions have been eliminated in consolidation.

Reporting Period

In 2001, Data I/O converted to reporting on a calendar year-end basis. The first
quarter of 2001 covered the period December 29, 2000 to March 31, 2001.

Use of Estimates

The  preparation  of the  financial  statements in  conformity  with  accounting
principles   generally  accepted  in  the  United  States  of  America  requires
management to make estimates and assumptions that affect the reported amounts of
assets and  liabilities  and disclosure of contingent  assets and liabilities at
the date of the financial  statements,  and the reported amounts of revenues and
expenses  during the reporting  period.  Actual  results could differ from those
estimates.

Stock-Based Compensation
Data I/O has  stock-based  employee  compensation  plans that are described more
fully in Note 13. Data I/O applies APB Opinion 25,  Accounting  for Stock Issued
to Employees,  and related  Interpretations  in accounting for our plans.  Stock
expense in 2003,  2002,  and 2001  would have been the result of options  issued
with an exercise price below the underlying  stock's market price. The following
table  illustrates the effect on net income (loss) and earnings (loss) per share
if Data I/O had applied the fair value recognition  provisions of FASB Statement
123, Accounting for Stock-Based Compensation, using the assumptions described in
Note 13, to our stock-based employee plans.

Foreign Currency Translation

Assets and  liabilities of foreign  subsidiaries  are translated at the exchange
rate on the  balance  sheet  date.  Revenues,  costs  and  expenses  of  foreign
subsidiaries are translated at average rates of exchange  prevailing  during the
year.  Translation  adjustments  resulting  from this  process  are  charged  or
credited to stockholders'  equity,  net of taxes.  Realized and unrealized gains
and losses resulting from the effects of changes in exchange rates on assets and
liabilities  denominated  in foreign  currencies  are included in  non-operating
expense as foreign currency transaction gains and losses.

In an effort to minimize the effect of exchange rate fluctuations on the results
of our  operations,  Data I/O hedges portions of our foreign  currency  exposure
through the use of forward exchange contracts, none of which are speculative. At
December 31, 2003,  we had a notional  value of  approximately  $623,000 in five
foreign exchange contracts outstanding,  the fair value of which was a liability
of  $31,000.  The  contract  terms are 43-90  days.  The  hedges  are  perfectly
effective, as currency, settlement date and amount of the underlying receivables
and of the forward contracts  coincide,  and as spot rates are the same for both
the hedge and the hedged item.

Cash and Cash Equivalents

Cash and cash equivalents are highly liquid investments with maturities of three
months or less at date of purchase.

Marketable Securities

Data I/O generally invests in debt securities with original maturities of twelve
months  or  less  and  money  market  funds,  all of  which  are  classified  as
available-for-sale  securities and recorded at fair value,  as defined below. We
record  unrealized  holding  gains  and  losses,  net of any  tax  effect,  as a
component of accumulated other comprehensive  income (loss) within stockholders'
equity.  We report interest earned in  non-operating  income as interest income.
Marketable  securities  are  classified  in the  balance  sheet as  current  and
noncurrent  based on maturity dates and our expectation of sales and redemptions
in the following year.

Fair Value of Financial Instruments

The carrying value of cash, cash equivalents,  marketable securities and forward
exchange  contracts  approximates  fair  value.  The fair  value  of Data  I/O's
marketable securities is based upon the quoted market price on the last business
day of the fiscal year plus accrued interest, if any.

Accounts Receivable

The majority of Data I/O's  accounts  receivable  are due from  companies in the
electronics manufacturing industries.  Credit is extended based on an evaluation
of a customer's financial condition and, generally,  collateral is not required.
Accounts  receivable  are  typically  due within 30 to 60 days and are stated at
amounts due from customers net of an allowance for doubtful  accounts.  Accounts
outstanding  longer than the contractual  payment terms are considered past due.
Data I/O determines our allowance by considering a number of factors,  including
the length of time trade  accounts  receivable are past due, Data I/O's previous
loss history,  the customer's current ability to pay our obligation to Data I/O,
and the condition of the general  economy and the industry as a whole.  Data I/O
writes off  accounts  receivable  when they become  uncollectible,  and payments
subsequently  received on such  receivables  are credited to the  allowance  for
doubtful  accounts.  Interest is allowed to accrue,  according  to our  standard
sales terms, beginning on the day after the due date of the receivable. However,
interest income is subsequently  recognized on these accounts only to the extent
cash is received,  or when the future  collection of interest and the receivable
balance is considered probable by management.

Inventories

Inventories  are  stated  at the lower of cost or  market  with  cost  being the
currently  adjusted  standard  cost,  which  approximates  cost  on a  first-in,
first-out basis.

Property, Plant and Equipment

Property, plant and equipment,  including leasehold improvements,  are stated at
cost and  depreciation  is  calculated  over the  estimated  useful lives of the
related  assets  or  lease  terms  on the  straight-line  basis.  We  depreciate
substantially  all  manufacturing  and office equipment over periods of three to
seven years. We depreciate leasehold  improvements over the remaining portion of
the lease,  or over the  expected  life of the asset if less than the  remaining
term of the lease.

Long-lived and other assets are evaluated on an annual basis for impairment.  In
this  connection,  we reviewed  the  expected  cash flows to be generated by the
Sprint  product  line to  determine  that  they  are  adequate  compared  to the
remaining net book value of long-lived assets from the SMS acquisition.

Revenue Recognition

Sales of Data  I/O's  semiconductor  programming  equipment  products  requiring
installation by us that is other than perfunctory are recorded when installation
is  complete,  or at the later of customer  acceptance  or  installation,  if an
acceptance  clause is specified in the sales  terms.  We recognize  revenue from
other product sales at the time of shipment.  We record revenue from the sale of
service and update  contracts  as  deferred  revenue  and we  recognize  it on a
straight-line  basis over the  contractual  period.  Sales were  recorded net of
associated sales return  reserves,  which were $300,000 and $450,000 at December
31, 2003 and 2002, respectively.

Data  I/O  previously  recognized  revenue  from  product  sales  at the time of
shipment,  or at customer  acceptance,  if an acceptance clause was specified in
the  sales  terms.  Effective  December  31,  1999,  we  changed  our  method of
accounting for product sales requiring Company  installation,  when installation
is other than  perfunctory,  to recognize  such  revenues when  installation  is
complete,  or at  the  later  of  customer  acceptance  or  installation,  if an
acceptance  clause is  specified  in the sales  terms.  We believe the change in
accounting  principle  is  preferable  based on  guidance  provided in SEC Staff
Accounting  Bulletin  No.  101  (SAB  101),  Revenue  Recognition  in  Financial
Statements.  This change in accounting  principle  did not impact taxes,  as all
affected jurisdictions had net operating loss carryforwards.

Data I/O's  software  products are not normally  sold  separately  from sales of
programming  systems.  However,  on  those  occasions  where  we  sell  software
separately,  we recognize revenue when a sales agreement  exists,  when delivery
has occurred, when the fee is fixed or determinable,  and when collectibility is
probable.

Research and Development

Research and development costs are expensed as incurred.

Advertising Expense

Data I/O expenses  advertising  costs as incurred.  Total  advertising  expenses
related to continuing operations were $248,000,  $468,000, and $487,000 in 2003,
2002, and 2001, respectively.

Warranty Expense

Data I/O records a  liability  for an estimate of costs that it expects to incur
under our basic limited  warranty when product  revenue is  recognized.  Factors
affecting our warranty liability include the number of units sold and historical
and anticipated rates of claims and costs per claim. We periodically  assess the
adequacy of our warranty  liability based on changes in these factors.  Data I/O
normally  warrants our products  against defects for periods ranging from ninety
days to one  year.  The  FlashPAK,  which  we  recently  introduced,  carries  a
three-year  warranty on some components.  We provide currently for the estimated
cost  that may be  incurred  under  our  product  warranties.  Data I/O  records
revenues on extended  warranties on a  straight-line  basis over the term of the
related warranty contracts. Service costs are expensed as incurred.

Earnings (Loss) Per Share

Basic earnings  (loss) per share exclude any dilutive  effects of stock options.
Basic earnings (loss) per share are computed using the  weighted-average  number
of common shares  outstanding  during the period.  Diluted  earnings  (loss) per
share are computed using the weighted-average number of common shares and common
stock equivalent shares outstanding  during the period.  Common stock equivalent
shares are excluded from the computation if their effect is antidilutive.

Earnings per share as presented on the statement of operations  exclude employee
stock options that were  antidilutive  of 1,141,412  and 1,115,508 in 2002,  and
2001, respectively.

Diversification of Credit Risk

Financial  instruments,  which potentially subject Data I/O to concentrations of
credit risk, consist primarily of trade receivables.  Our cash, cash equivalents
and marketable  securities consist of high quality financial  instruments.  Data
I/O maintains cash balances in financial institutions, which at times may exceed
federally  insured  limits.  We have not experienced any losses in such accounts
and believe we are not exposed to any  significant  credit risk on cash and cash
equivalents.  Our trade  receivables  are  geographically  dispersed and include
customers  in many  different  industries.  We believe  that any risk of loss is
significantly  reduced due to the diversity of our  end-customers and geographic
sales areas. We perform on-going credit evaluations of our customers'  financial
condition and require collateral, such as letters of credit and bank guarantees,
whenever deemed necessary.

Derivatives

Data I/O  accounts  for our  derivatives  using SFAS No.  133,  "Accounting  for
Derivatives and Hedging Activities." This statement  establishes  accounting and
reporting  standards for  derivative  instruments  and requires  recognition  of
derivatives as assets or liabilities in the statement of financial  position and
measurement of those instruments at fair value.

Data I/O utilizes  forward  foreign  exchange  contracts to reduce the impact of
foreign currency exchange rate risks where natural hedging  strategies cannot be
effectively  employed.  All of our hedging  instruments  are fair value  hedges.
Generally,  these contracts have maturities less than one year and require us to
exchange foreign currencies for U.S. dollars at maturity.  The fair value of the
open hedge  contracts  as of December  31, 2003 is a liability of $31,000 and is
included in accounts payable on the balance sheet.

Data I/O does not hold or issue  derivative  financial  instruments  for trading
purposes.  The purpose of our hedging  activities is to reduce the risk that the
valuation of the underlying  assets,  liabilities and firm  commitments  will be
adversely  affected by changes in exchange rates.  Our derivative  activities do
not create foreign currency exchange rate risk because fluctuations in the value
of the instruments  used for hedging  purposes are offset by fluctuations in the
value of the underlying exposures being hedged. We are exposed to credit-related
losses in the event of  nonperformance  by  counterparties  to forward  exchange
contracts.  However,  we have entered into these  instruments with  creditworthy
financial institutions and consider the risk of nonperformance remote.

New Accounting Pronouncements

During 2001, the Financial Accounting Standards Board (FASB) issued Statement of
Financial  Accounting  Standards (SFAS) No. 143 "Accounting for Asset Retirement
Obligations"  and,  during 2002,  the FASB issued SFAS No.146,  "Accounting  for
Costs Associated with Exit and Disposal  Activities".  The adoption of SFAS Nos.
143  and  146  during  fiscal  2003  did  not  have  a  material  impact  on our
consolidated financial statements.

In November  2002,  the  Emerging  Issues Task Force (EITF)  released  Issue No.
02-16,   "Accounting   by  a  Customer   (including  a  Reseller)   for  Certain
Consideration  Received from a Vendor",  applicable to Data I/O for arrangements
entered into beginning in fiscal 2003.  Data I/O records  vendor  allowances and
discounts in the income  statement  when the purpose for which those monies were
designated is fulfilled.  As such,  the adoption of EITF No. 02-16 during fiscal
2003 did not have a material impact on our consolidated financial statements.

In November 2002, the Emerging Issues Task Force reached a consensus  opinion on
EITF 00-21,  "Revenue  Arrangements with Multiple  Deliverables."  The consensus
provides that revenue arrangements with multiple  deliverables should be divided
into separate units of accounting if certain criteria are met. The consideration
for the  arrangement  should be allocated to the  separate  units of  accounting
based on their relative fair values, with different provisions if the fair value
of all deliverables are not known or if the fair value is contingent on delivery
of specified items or performance  conditions.  Applicable  revenue  recognition
criteria  should be considered  separately for each separate unit of accounting.
EITF 00-21 is effective for revenue  arrangements entered into in fiscal periods
beginning  after  June 15,  2003.  Entities  may elect to report the change as a
cumulative  effect  adjustment  in  accordance  with APB Opinion 20,  Accounting
Changes. Data I/O has adopted the provisions of the statement,  which has had no
material impact.

In January 2003, the FASB issued  Interpretation 46,  "Consolidation of Variable
Interest  Entities"  (FIN  46).  FIN 46  interprets  ARB No.  51,  "Consolidated
Financial  Statements," as amended by FASB Statement No. 94,  "Consolidation  of
All Majority-Owned Subsidiaries," which requires the preparation of consolidated
financial  statements when one entity has a controlling  financial interest in a
second  entity.  FIN 46 specifies  disclosures  that are required for  financial
statements  issued after January 31, 2003 but prior to the effective date of the
Interpretation  for entities  created  before  February 1, 2003 and interests in
those entities  acquired  before that date, as well as disclosures  that will be
required  for  financial  statements  of primary  beneficiaries  and others with
variable  interests in variable  interest  entities  issued after the  effective
date. The FASB has published a revision to  Interpretation 46 to clarify some of
the provisions of FIN 46 and to exempt certain entities from its provisions. The
adoption of this interpretation did not have a material impact on our results of
operations or financial position, as we do not have variable interest entities.

In April 2003, the FASB issued Statement No. 149, "Amendment of Statement 133 on
Derivative  Instruments  and  Hedging  Activities."  The  Statement  amends  and
clarifies  accounting for derivative  instruments,  including certain derivative
instruments  embedded  in other  contracts,  and for  hedging  activities  under
Statement 133. Data I/O has adopted the  provisions of the statement,  which has
had no material impact.

In May  2003,  the FASB  issued  Statement  No.  150,  "Accounting  for  Certain
Financial  Instruments with Characteristics of both Liabilities and Equity." The
statement  requires that certain  financial  instruments,  which under  previous
guidance were accounted for as equity, must now be accounted for as liabilities.
This  statement  is  effective  for all  financial  instruments  entered into or
modified after May 31, 2003." The adoption of SFAS No 150 during fiscal 2003 did
not have a material impact on our consolidated financial statements.

NOTE 2 - PROVISION FOR BUSINESS RESTRUCTURING

During  2003,  we completed  the  restructuring  that began  during 2001,  which
included  actions taken to reduce our breakeven  point and realign Data I/O with
our market opportunities.  We required this operational repositioning because of
the impact of the economic slowdown and the decline in capital spending across a
high number of customer groups on general demand for programming  equipment over
the past few years.  At the end of 2003 our  breakeven  point was  approximately
$6.2 million in net sales with 127  employees  worldwide.  Our  breakeven  point
increased in 2003,  primarily due to cost increases resulting from the impact of
the weaker dollar on foreign  currency based costs and from personnel  costs due
to salary increases,  incentive compensation and selective hiring of individuals
with critical skills to help position us as the continuing  technology leader in
our market.

During 2002, we recorded  restructuring  charges of $632,000 in connection  with
our  actions to reduce our  quarterly  breakeven  point  from  approximately  $7
million of net sales at the beginning of 2002 to  approximately  $5.7 million at
the end of 2002. We achieved most of these  reductions by reducing our personnel
from 155 at the beginning of 2002 to 125 at the end of 2002.

During 2001, we recorded  restructuring charges of $1,211,000 in connection with
a number of strategic  restructuring actions to reduce our breakeven point. This
restructuring  included the following:  a reduction in our global workforce from
224 at the  start  of the  year to 155 at the  end of  2001;  discontinuance  or
reallocation of numerous  projects and activities not essential to our long-term
goals; streamlining activities to decrease discretionary marketing, distribution
and  promotional  expenses;  consolidation  of  numerous  functions  across  the
organization  to create a team,  which was more  productive  and able to respond
faster to global customer needs; and closure of a facility in Germany and moving
our operations to other locations within Data I/O.

At December 31, 2003 all restructuring  expenses  associated with the activities
detailed  above had been paid and the excess  expense  accrual  of  $39,000  was
reversed during 2003.

An analysis of the restructuring is as follows (in thousands):

NOTE 3 - RESTATEMENT OF FINANCIAL STATEMENTS

During  the  preparation  of our 2004  year-end  financial  statements  and more
specifically the inter-company profit elimination  associated with demonstration
inventory  equipment  amounts,  the Company identified  elimination  calculation
omission errors that had resulted in the understatement of inter-company expense
elimination   on   foreign   subsidiary    demonstration   inventory   equipment
depreciation,  with a corresponding  overstatement  of  demonstration  inventory
equipment accumulated  depreciation  (international  selling) expense associated
with the Company's foreign subsidiaries.

The  cumulative  impact of this error as of December  31,  2003,  including  the
related income tax effect, resulted in a $112,000 overstatement of demonstration
inventory equipment accumulated deprecation reserve and a $112,000 overstatement
of depreciation (international selling) expense. The income tax effects from the
cumulative  effect of this  error had no impact on income tax  expense  and only
impacted the related disclosure of net operating losses in carry forward and the
related valuation allowances.

The Company has evaluated  that the  adjustments  to the quarters other than the
fourth  quarter  are  immaterial  and that the entire  2003  adjustment  will be
reflected as a correction to the fourth quarter of 2003 in the amount of $65,000
and that accordingly no restatement is necessary for the interim  quarterly Form
10-Q filings.  The Company has determined that there were no material impacts on
the 2002 and 2001 Consolidated Statement of Operations.

The impacts of this  restatement on the financial  statements for the year ended
December  31,  2003  are  summarized  below  (in  thousands,  except  per  share
information):

At December 31, 2003, cost approximated market value for Data I/O's portfolio of
marketable securities and there were no significant  unrealized gains or losses.
The  marketable  securities  are all  classified as current  assets due to their
maturity  date or because of the available  for sale holding  intent,  as in the
case of corporate  bonds having a maturity  date in the second  quarter of 2005.
The cost of securities sold is determined by the specific identification method.

                                             =============      ==============


Reserves for excess and obsolete  inventory  were  $2,296,000  and $3,267,000 at
December 31, 2003 and December 31, 2002,  respectively.  The $971,000 decline in
the reserve related primarily to scrapping and disposal of the related inventory
and reversal of $96,000 in cost of goods sold.  Freight expense for incoming raw
materials  and  freight out for  product  shipments  is charged to cost of goods
sold.

Certain parts used in Data I/O's products are currently  available from either a
single  supplier or from a limited  number of  suppliers.  If we cannot  develop
alternative sources for these components,  or if we experience  deterioration in
our  relationship  with these  suppliers,  there may be delays or  reductions in
product  introductions or shipments,  which may materially  adversely affect our
operating results.

Because Data I/O relies on a small number of suppliers for certain parts, we are
subject to possible price increases by these  suppliers.  Also, we may be unable
to  accurately  forecast  our  production  schedule.  If  we  underestimate  our
production schedule,  suppliers may be unable to meet our demand for components.
This delay in the supply of key components may materially  adversely  affect our
business.

The non-automated  programming system products we acquired when we purchased SMS
in  November  1998  are  currently  manufactured  to  our  specifications  by  a
third-party  contract  manufacturer.  We may not be able to obtain a  sufficient
quantity of these products when needed, which may result in lost sales.

NOTE 7 - SALE - LEASEBACK

In May 1997, Data I/O completed the sale of the land and building comprising our
Redmond,  Washington,  corporate  headquarters.  The  sale  includes  a  10-year
leaseback of the building to Data I/O. The sale  represented an overall  pre-tax
gain to Data I/O of $5.6 million.  Of this amount, we recognized $2.3 million in
1997, with the remainder being amortized over the life of the lease.

Total amortization  recorded for 2003, 2002, and 2001 was $59,000,  $81,000, and
$969,000, respectively.

Investment In Product Lines: SMS

In November 1998,  Data I/O acquired SMS Holding GmbH. In related  transactions,
we  acquired  a  license  to  the   technology,   manufacturing   and  worldwide
distribution rights to Unmanned Solutions' AH 400 robotic handler, which is used
in the fine pitch automated  programming  system,  now the PS product family. Of
the total acquisition costs of these transactions, approximately $3.3 million of
developed  technology and other various  intangible assets are reported as Other
Assets in the accompanying  balance sheets and are being amortized  ratably over
the economic life of the specific assets acquired (three to five years). The net
book value of the assets capitalized in Other Assets related to this acquisition
is $0 and $59,000 at December 31, 2003 and 2002, respectively.

NOTE 11 - AGGREGATE CONTRACTUAL OBLIGATIONS AND COMMITTMENTS

Data I/O has purchase  obligations for inventory and production costs as well as
other obligations such as capital  expenditures,  service contracts,  marketing,
and development agreements.  Arrangements are considered purchase obligations if
a  contract  specifies  all  significant  terms,   including  fixed  or  minimum
quantities to be purchased,  a pricing  structure and approximate  timing of the
transaction. Most arrangements are cancelable without a significant penalty, and
with short notice,  typically  less than 90 days.  Any amounts  reflected on the
balance sheet as accounts payable and accrued  liabilities are excluded from the
below table.  Data I/O has no long-term  debt.  Data I/O has  commitments  under
non-cancelable operating leases and other agreements,  primarily for factory and
office space, with initial or remaining terms of one year or more as follows:

                                   ================         ================

Lease and rental expense was $1,476,000, $1,387,000 and $1,342,000 in 2003, 2002
and 2001, respectively. Data I/O has renewal options on substantially all of our
major leases.  The initial lease on the Redmond facility expires on December 31,
2006.  So long as we are not in  material  default of the terms of the lease and
there has not been a material adverse change in the financial  condition of Data
I/O, we have the option to extend the lease for an additional  five years on the
same  terms  as the  balance  of the  lease,  except  the  rent  shall be at the
then-prevailing  fair  market  rental  rate.  We will  also have the right for a
second five-year extension by giving written notice at least six months prior to
the end of the first extension.

As part of our restructuring plan implementation,  Data I/O vacated one floor of
our leased Redmond  facility  (approximately  25,000 square feet) and sublet the
majority of this space for a period of 28 months beginning January 1, 2000. This
sublease  ended in June 2002. We have not been  successful  in  subleasing  this
space since June 2002 and believe the market for this space is  currently  quite
limited.

NOTE 12 - STOCK AND RETIREMENT PLANS

Stock Option Plans

At December 31, 2003,  there were 1,595,215  shares of Common Stock reserved for
issuance of which 268,410 shares are available for future grant under Data I/O's
employee stock option plans. Pursuant to these plans, options are granted to our
officers and key employees  with exercise  prices equal to the fair market value
of the Common  Stock at the date of grant and  generally  vest over four  years.
Certain  options  granted  during  1998 and 1999  vest over two  years.  Options
granted under the plans generally have a maximum term of six years from the date
of grant,  except for  certain  options  granted in January  1999,  which have a
maximum term of ten years. On May 15, 2002, Data I/O's shareholders  approved an
amendment to the Data I/O  Corporation  2000 Stock Incentive  Compensation  Plan
increasing the number of shares  reserved for issuance under the 2000 Plan by an
additional 200,000 shares of Common Stock.

Employee Stock Purchase Plan

Under the Employee Stock Purchase Plan,  eligible  employees may purchase shares
of Data I/O's  Common  Stock at  six-month  intervals at 85% of the lower of the
fair  market  value  on the  first or the  last  day of each  six-month  period.
Employees  may purchase  shares  having a value not exceeding 10% of their gross
compensation  during an offering period.  During 2003, 2002 and 2001, a total of
194,477,  148,876,  and 119,212 shares,  respectively,  were purchased under the
plan at average prices of $0.61,  $0.87, and $1.66 per share,  respectively.  At
December 31, 2003, a total of 274,638 shares were reserved for future issuance.



Stock Appreciation Rights Plan

Data I/O has a Stock Appreciation Rights Plan ("SAR") under which each director,
executive  officer or holder of 10% or more of Data I/O's Common Stock has a SAR
with respect to each exercisable  stock option.  The SAR entitles the SAR holder
to receive cash from Data I/O for the difference between the market value of the
stock and the  exercise  price of the option in lieu of  exercising  the related
option. SARs are only exercisable following a tender offer or exchange offer for
Data I/O's  stock,  or  following  approval by  shareholders  of Data I/O of any
merger,  consolidation,  reorganization or other  transaction  providing for the
conversion or exchange of more than 50% of the common shares outstanding.  As no
event has occurred, which would make the SARs exercisable,  and no such event is
deemed probable, no compensation expense has been recorded under this plan.

Director Fee Plan

Data I/O has a Director Fee Plan,  not currently in use,  which had provided for
payment to directors who are not employees of Data I/O  Corporation  by delivery
of shares of Data I/O's  Common  Stock.  No shares were issued from the plan for
2003,  2002 or 2001 board  service and 151,332  shares  remain  available in the
plan.

Retirement Savings Plan

Data  I/O  has a  savings  plan  that  qualifies  as a cash or  deferred  salary
arrangement  under Section 401(k) of the Internal  Revenue Code. Under the plan,
participating  U.S.  employees  may defer their pre-tax  salary,  subject to IRS
limitations.  In fiscal  years 2003,  2002 and 2001,  Data I/O  contributed  one
dollar for each dollar contributed by a participant, with a maximum contribution
of 4% of a participant's  earnings. Data I/O's matching contribution expense for
the savings plan was approximately $161,000, $173,000 and $271,000 in 2003, 2002
and 2001, respectively.

Share Repurchase Program

Under a previously announced share repurchase program, Data I/O is authorized to
repurchase  up to  1,123,800  shares  of our  outstanding  Common  Stock.  These
purchases may be executed  through open market  purchases at  prevailing  market
prices, through block purchases or in privately negotiated transactions, and may
commence  or be  discontinued  at any  time.  In years,  prior to 2003,  we have
repurchased  1,016,200  shares under this repurchase  program at a total cost of
approximately $7.1 million. We have not repurchased shares under this plan since
the second quarter of 1997, although we still have the authority to do so.

NOTE 13- STOCK-BASED COMPENSATION

Pro forma information regarding net income and earnings per share is required by
SFAS 123, and has been  determined as if Data I/O had accounted for our employee
stock  options,  employee  stock purchase plan options and directors' fee shares
under the fair value method of that Statement.  The fair value for these options
was estimated at the date of grant using a  Black-Scholes  option-pricing  model
with the following weighted-average assumptions:

The valuation  allowance for deferred tax assets  decreased  $424,000 during the
year ended  December 31, 2003, due primarily to the 2003 net income that allowed
the  utilization of tax deferred assets  reducing the valuation  allowance.  The
valuation allowance for deferred tax assets increased $1,173,000 during the year
ended  December  31,  2002,  due  primarily  to  taxable  losses  and to  credit
carryforwards  generated  in  2002.  The net  deferred  tax  assets  have a full
valuation allowance provided due to uncertainty  regarding Data I/O's ability to
utilize such assets in future years. Credit  carryforwards  consist primarily of
research and  experimental  and alternative  minimum tax credits.  Net operating
loss carryforwards expire in 2019 to 2023. Utilization of net operating loss and
credit  carryforwards is subject to certain limitations under Section 382 of the
Internal Revenue Code of 1986, as amended.

NOTE 16 - SEGMENT AND GEOGRAPHIC INFORMATION

In 2003, one customer accounted for 18% of Data I/O's consolidated  revenues and
no other  customer  accounted for more than 10%. No customer  accounted for more
than 10% of consolidated revenues in 2002 and 2001. Major operations outside the
U.S.  include  sales and service  support  subsidiaries  in Germany,  Canada and
China.

We present  geographic  information of the  continuing  operations for the three
years ended December 31, 2003 in the table that follows.  Net sales, as shown in
the table below, are based upon the geographic area into which the products were
sold and  delivered.  Export  sales are subject to U.S.  Department  of Commerce
regulations, and to the market conditions in the countries in which the products
are sold. For purposes of the table below,  the profit on the transfers  between
geographic areas has been shown in operating income in the geographic area where
the final sale to non-affiliated customers took place. Certain general corporate
expenses are charged to the U.S. segment.  Identifiable  assets are those assets
that can be directly  associated with a particular  geographic area. All Company
financial  instruments,  consisting  of  cash  and  marketable  securities,  are
included in U.S. operations.

NOTE 17 - QUARTERLY FINANCIAL INFORMATION (unaudited)

The following table sets forth unaudited selected  quarterly  financial data for
Data I/O for 2003 and 2002. Although our business is not seasonal,  growth rates
of sales and earnings have varied from quarter to quarter as a result of factors
such as  stocking  orders  from  international  distributors,  the timing of new
product   introductions,   business  acquisitions  and  dispositions,   business
restructuring,  and  short-term  industry  and general  U.S.  and  international
economic  conditions.  Information as to any one or more quarters is, therefore,
not necessarily indicative of trends in our business or profitability.

NOTE 18  - LONG-TERM DEBT

As of December 31, 2003 and December  31, 2002,  Data I/O had no long-term  debt
outstanding.  Data I/O  established a foreign line of credit for 50,000 Euros in
February 2002 that was renewed in 2003, but we did not renew it in January 2004.




Item  9.  Changes  in and  Disagreements  with  Accountants  on  Accounting  and
          Financial Disclosures

Not Applicable

Item 9A.  Controls and Procedures

(a) Evaluation of disclosure controls and procedures.

Under the supervision and with the  participation  of our management,  including
our Chief Executive Officer and Chief Financial Officer,  Data I/O evaluated the
effectiveness  of the  design  and  operation  of our  disclosure  controls  and
procedures (as defined in Rule  13a-15(e) and Rule 15d-15(e)  under the Exchange
Act) as of the end of the period covered by this report (the "Evaluation Date").
Based upon that  evaluation,  the Chief  Executive  Officer and Chief  Financial
Officer  concluded that, as of the Evaluation Date, our disclosure  controls and
procedures  were effective in timely  alerting them to the material  information
relating to Data I/O (or our consolidated  subsidiaries) required to be included
in our periodic SEC filings and Form 8-K reports.

(b) Changes in internal controls.

There were no  significant  changes  made in our  internal  controls  or, to our
knowledge,  in other  factors that could  significantly  affect  these  controls
subsequent to the date of their evaluation.

During the  preparation  of our 2004  year-end  financial  statements,  Data I/O
identified  a  calculation  error that had  resulted  in the  understatement  of
inter-company expense eliminations on foreign subsidiary demonstration inventory
equipment  depreciation,  with a corresponding  overstatement  of  demonstration
inventory  equipment  accumulated  depreciation.  While  Data I/O  believes  the
impacts of this  calculation  error are not  material to any  previously  issued
financial  statement,  Data I/O determined that this calculation  error was most
appropriately  corrected  through  restatement  of previously  issued  financial
statements.

Process  changes  have since been  instituted  to  appropriately  eliminate  the
inter-company foreign subsidiary  demonstration inventory equipment depreciation
amounts.

See Note 3 to the  Consolidated  Financial  Statements  for the  impact  of this
restatement on previously issued financial statements.

our Code of Ethics at that  location.  In the  unlikely  event that the Board of
Directors  approves  any sort of waiver to the Code of Ethics for our  executive
officers or directors, information concerning such waiver will also be posted at
that  location.  In addition to posting  information  regarding  amendments  and
waivers on our  website,  the same  information  will be  included  in a Current
Report on Form 8-K within five business days following the date of the amendment
or waiver,  unless website posting of such amendments or waivers is permitted by

   b) any fraud,  whether or not material, that involves  management or other
      employees who have a significant role in the registrant's internal
      controls over financial reporting.
