           DATA I/O REPORTS SIXTH CONSECUTIVE QUARTER OF PROFITABILITY

Redmond,  Washington (April 23, 2004) -- Data I/O(R) Corporation (NASDAQ:  DAIO)
today  announced a net income for the first quarter of 2004 of $296,000 or $0.04
per share,  compared to a net income of  $317,000,  or $0.04 per share,  for the
first quarter of 2003. Revenues for the first quarter of 2004 were $6.8 million,
up 11% compared to $6.2 million for the first quarter of 2003.

Gross  margins  increased by $276,000 in the first quarter of 2004 compared with
the same period of 2003. This was primarily due to the higher sales level and an
increase in the  aftermarket  sales mix.  Operating  expenses were higher in the
first quarter of 2004 compared to the first quarter of 2003 due primarily to the
company's  strategic  investments  in Asia  and in a new  venture  in  in-system
programming  (ISP)  under  development,  as  well  as the  unfavorable  currency
translation  impact of  European  based  operating  costs.  The  company's  lean
manufacturing  processes continued to show results helping to reduce inventories
by $555,000 during the quarter.

During the quarter, the Company added Joe Murdica as Vice President of Sales for
the Americas and Asia. He joined in the introduction, at the APEX trade show, of
the new PS-288FC automated programming system along with several other products.
This month,  the  Company  formed a new  subsidiary  in Brazil  specifically  to
support Siemens ICM handset production in Manaus.

"I am  pleased  to report  profitable  revenue  growth at the same time that the
company is making a significant  investment to position itself to take advantage
of the  growth in the Asian  market for our  products,"  stated  Fred Hume,  the
company's  President  and CEO. "As the  geographical  center of the  electronics
manufacturing industry has shifted to Asia, we have redeployed resources to that
region and are adding staff  locally.  This will allow us to service and support
our customers  there in their time zone. We have also invested in  strengthening
our sales  organization  globally in  recognition  of the improving  climate for
capital equipment."

Second  Quarter  2004  Forward-Looking  Statement:  Management  is  committed to
long-term  profitable  growth and believes  that the  financial  results for the
current quarter will be generally in line with the previous quarter. The Company
remains in a strong  financial  position with a cash and  short-term  investment
position of $6.1 million and no debt at the end of the first quarter.


Web-Cast  Conference  Call:  The Company has  scheduled  a  conference  call for
Friday,  April 23, 2004 at 8:30 a.m.  Pacific Time  regarding  its first quarter
results and a business update that will be broadcast on the web. Please see Data
