VALID TO BUY $120 MILLION OF SUN MICROSYSTEMS EQUIPMENT 
 
Includes New SPARC-based Systems
  
 
MOUNTAIN VIEW, Calif. --  August 15, 1989 --  Sun Microsystems today
announced that Valid Logic Systems, a leading supplier of elecronic
design automation (EDA) tools, has agreed to purchase $120 million of
Sun equipment through November of 1990.  Covering Sun's entire product
line, this is one of the largest purchase agreements for Sun equipment
to date and the largest from any EDA vendor.

"We believe this is the largest EDA deal, ever," said Ed Zander, vice
president of corporate marketing at Sun.  "This market is very
important to Sun, since 85 percent of EDA vendors make their products
available on our systems.  Agreements with leading vendors like Valid
have made our growth in this area possible."

In the planned purchase are new products introduced recently by Sun,
including RISC-based SPARCstation (TM)  1 desktop systems and
SPARCstation 330 and 370 deskside workstations.  Valid was one of the
first companies to commit to the new Sun systems, placing a $4.6
million order on the day of their introduction.  Valid plans to use the
systems for internal product development and for resale, along with
Valid software, to customers in the United States, Europe and the Far
East.

"We have seen strong demand among our customers for Sun's SPARC (TM)
systems," said Dick Albright, director of marketing for integration
products at Valid.  "The SPARCstation family gives new levels of
performance to users of our advanced EDA tools, particularly our
integrated circuit and printed circuit board design tools, which take
advantage of Sun's GX graphics technology," he said.

Nearly 60 percent of Valid's second quarter sales were SPARC-based RISC
systems, reinforcing its position as the number one supplier of
RISC-based EDA products, he added.

Valid, one of Sun's major resellers, is a leading supplier of EDA tools
on Sun systems.  Valid's products are used as part of Sun's internal
EDA environment and contributed to the board-level design of the
SPARCstation 1.

The SPARCstation 1 can deliver 12.5 MIPS in a package smaller than an
IBM PC while offering many ease-of-use features.  Its processing power
and optional graphics capabilities enable the SPARCstation 1 to be used
throughout the electronic design process.

The SPARCstation 330 and 370 are the highest-performance systems Sun
offers, delivering 16 MIPS and 2.6 MFLOPS.  They provide the large
amounts of memory (up to 56 megabytes), extra disk storage and
expansion needed for a variety of high-end EDA applications.  In
addition, they are designed so that specialized subsystems and
high-speed accelerators can be added.

Sun Microsystems, Inc., headquartered in Mountain View, Calif., is a
leading worldwide supplier of network-based distributed computing
systems, including professional workstations, servers and UNIX(R)
operating system and productivity software.
