   Stac Launches Rescue Mission for DoubleSpace Users

__________________________________________________________________________

CARLSBAD, Calif., May 10, 1993 — Stac Electronics (NASDAQ:STAC), the

leading supplier of high performance data compression, today

announced a Special Edition of Stacker 3.1 for Windows & DOS.  The

program is designed to help users of MS-DOS 6.0 avoid a variety of

problems, including loss of data, that have been attributed to the

new operating systems DoubleSpace compression utility.

"With the growing number of reports of the possible problems that

users could encounter  with DoubleSpace, we felt we had no

alternative but to put together a rescue mission to go to the aid of

those 2 million or more MS DOS 6.0 users before its too late," said

John Bromhead, Stac’s director of marketing.  "We have developed

technology that can almost instantaneously retrofit all the benefits

of the Stacker File System to a DoubleSpace drive and hopefully

preserve both the users data and the good name and reputation of the

data compression industry."

The Special Edition installs the latest version of Stac’s

award-winning compression software, Stacker 3.1, on systems running

MS-DOS 6.0, and within minutes automatically updates the DoubleSpace

drive to include the proven safety features of the Stacker file

system.  All new files written to the updated DoubleSpace drive will

then utilize the proven Stacker LZS compression technology.  Users

also have the option to fully convert their existing Doublespace

drives to use Stacker LZS compression and realize even larger disk

capacity.

Scheduled to begin shipping in June, the Special Edition will be

available through retail channels for the suggested promotional price

of $49.95 through August 31 and for $99.95 after that.

Stacker 3.1 --- the most recent addition to the Stacker line of data

compression products for DOS, Windows, Macintosh and OS/2 computers--- 

is based on Stac’s patented LZS_, which is relied upon daily by more than 

4 million users worldwide.

Stacker 3.1 Special Edition is for MS-DOS 6.0 only.  The program

seamlessly integrates the Stacker LZS_ compression technology into

MS-DOS 6.0 by taking advantage of special operating system features. 

As a result, Stacker drivers are transparently loaded before

CONFIG.SYS and AUTOEXEC.BAT files.This eliminates any risk of

accidental deletion by the user and allows all standard DOS commands,

such as DIR and CHKDSK, to work directly on Stacker drives.

In addition to its superior compression and performance over

DoubleSpace,Stacker 3.1 Special Edition also provides the additional

Windows functionality and disk optimization features that have made

Stacker for Windows and DOS, the No. 1 selling utility, according to

PC/Computing, April, 1993.  These features, which evolved over three

generations of product development in response to user needs,

include:

o The Windows Stackometer_:  Graphical gauges that allow Windows

  users to monitor disk capacity, compression ratio and fragmentation

  levels continuously, in real time.

o Flexible Setup:  Express Setup installs Stacker with a few

  keystrokes or mouse-clicks; Custom Setup allows users to tailor

  Stacker for optimal system performance.

o Compression Tuning:  Allows users to optimize their systems for

  maximum speed (on older, slower computers) or maximum compression

  ratio (on newer, faster systems).

o Stacker Anywhere_:  Allows users to read and write to any removable

  media on any PC, even one where Stacker is not installed.

o Stacker Automount_: Makes Stacker removables immediately available for use.

o Two-gigabyte drives:  up to 1G drives, yielding 2G Stacker drives.

o Stacker Optimizer_: data quickly; offers a visual representation of process.

Stacker AutoProtect_:  Detects disk errors dynamically and at boot

time and immediately protects your Stacker volume.

o Stacker AutoRecovery_:  Automatically repairs errors on the disk.

o Stacker Security_:  Password-protects Stacker drives for read-only

  or read/write access.
