Stac Announces OS/2 Version of Stacker



     Chicago, April 6, 1992 -- Stac Electronics announced today

at COMDEX/Spring '92 that a new version of its award-winning data

compression software is being designed for OS/2* 2.0, IBM's 32-

bit operating system for 386SX PCs and above.

     Stacker for OS/2 will allow users to start their systems

with OS/2 or DOS and access their existing Stacker drives without

any modification while running either operating system.  It will

also be 100% compatible with Stac's line of coprocessor boards

for maximum speed and compression ratios.

     The OS/2 version of Stacker, like the entire Stacker line of

data compression software and coprocessor boards, doubles a

computer's storage capacity with the Stacker LZSTM technology,

which is instantaneous, continuous, and totally transparent to

the user.

     "Stac has received strong demand from its installed base for

an OS/2 version of Stacker," said Gary Clow, Stac's president.

"We have been quietly engaged in developing Stacker for OS/2 for

more than a year now, and this summer we will supply a beta

release to the 300,000 OS/2 2.0 beta testers."

     Clow said Stacker for OS/2 will be available later this year

through Stac OEMs, the company's existing retail channels or

ordered directly from Stac by calling (800) 522-7822.  All

Stacker products come with free technical support.

     Stacker OS/2 will join the Stacker line of products that now

includes Stacker 2.0 software for laptop, notebook and portable

computers, and Stacker AT/16 and Stacker MC/16 compression

coprocessor boards for desktop systems.

     OS/2 2.0 offers true multitasking and will provide the

broadest selections of applications in the industry, running DOS,

Windows and 16- and 32-bit OS/2 applications unchanged, according

to IBM.

     Stac Electronics, based in Carlsbad, California, is the

leading supplier of high-performance data compression software

and silicon.  The company's products, designed for corporate-wide

compression applications, are sold direct from the company and

through traditional retail and OEM sales distribution.
