STACKER NOTE STACKER NOTE
Stac Unveils Stacker 3.0 for Windows and DOS

Stac Unveils Stacker for Windows and DOS. New Release Provides Tools for
Monitoring and Tuning Performance Enhancements.
CARLSBAD, Calif., October 26, 1992 - Stac Electronics (NASDAQ:STAC), the
leading supplier of high performance data compression for IBM PCs and
compatibles, today announced the availability of Stacker 3.0 for Windows
and DOS. This new version, which installs from Windows or DOS, enhances
Stacker's disk doubling capabilities with increased performance, data
security and new tools that enable users to monitor and tune the
compression and performance of their systems. "Stacker has been designed
for the Windows user who isn't necessarily out of disk space," said
Gary Clow, Stac's president and chief executive officer. "By
installing Stacker from the start, Windows users get the benefit of using
our new monitoring tools that function like the gauges on a car dashboard
to keep tabs on the disk drive."
Monitoring Gives Insights into Drive Performance: Stackometer
Windows users can monitor their systems with the new Stackometer, a set of
real-time gauges showing disk capacity, compression ratio and fragmentation
levels. The Stackometer can display any or all of a user's drives
simultaneously, providing useful feedback at a glance. DOS users can get
information on their systems with a new tool that gives drive statistics
based on the compression ratios of various file types.
Flexible Setup for Less Technical and Advanced Users Alike
"Stacker for Windows and DOS caters to the needs of a full range of
users,"said Anne Galdos, Stacker product manager. "We've made installation
much easier for less technical users who simply want to double their disk
capacity, and we provide the tools and functionality for advanced users who
want to customize and maximize system performance." Stacker now offers an
Express Setup that Stacks a system with minimal user interaction. This can
be accomplished from either Windows or DOS. In addition, Stacker provides
comprehensive, context-sensitive on-line help in both Windows and DOS.
Stacker's Custom Setup offers the more experienced user a host of
configuration options for maximum control These options include expected
compression ratio, cluster size, EMS support, and path statement
modification. Custom Setup also provides users the ability to tune their
systems from maximum speed or maximum compression.
Tuning: Customizing Compression for Optimal Performance
Stacker now allows users to maximize the performance of their systems by
tuning the speed and compression ratio. The default setting gives the
fastest performance and uses the least amount of memory. By changing the
settings, users can opt for more compression - up to 10 percent - with and
only a small decrease in speed. This means that on a 200 MB drive, users
can gain up to 40 MB of additional space. In a typical Windows
environment, this might mean being able to add two new applications. In
addition, users of faster machines may wish to maximize their systems for
compression, since for them the speed tradeoff is likely to be
imperceptible.
Password Protection
Users can password-protect Stacked drives for either read-only or
read/write access. This feature offers security for all files on a Stacked
drive. By choosing read-only, users can allow others to read files but not
to alter the data. Read/write access allows users full access to the data
providing they know the password.
Read and Write Stacked Floppies on Any System: Stacker AnywhereÖ
Stacker for Windows and DOS allows users to both read and write Stacked
floppies, Bernoulli disks, Syquest cartridges, Flopticals or any removable
media on any PC, even one where Stacker is not installed. With Stacker
Anywhere, data can truly be shared across all PCs easily and transparently.
Support for 2 Gigabyte Disk Drives
Stacker for Windows and DOS now supports Stacked drives up to 1 gigabyte in
size, yielding 2 gigabyte Stacker drives. Previous versions of Stacker
were limited to 512 megabytes per Stacker drive.
Faster and More Flexible Stacker Optimizer
Stacker's disk optimizer has been improved to provide a substantial
increase in speed. In addition, the optimizer has been enhanced, providing
visual representation of the defragmentation process on screen, similar to
popular disk utility products. A new quick defragmentation option has been
added to speed the process even further.
UnStack
With Stacker for Windows and DOS, users now have the ability to UnStack
compressed disks. Designed primarily for corporate software evaluators, the
UnStack command automatically returns the system to its original state.
Transparency
Stac has made several enhancements to make Stacker's operation even more
seamless than before. Stacker Setup recognizes Windows permanent swap
files and handles them automatically. The Automount feature means that
Stacked removable drives are immediately ready to use. Improved
synchronization means Stacker detects changes to a user's configuration,
and automatically updates system files.
Compatibility
As with all Stacker products, Stacker for Windows and DOS is compatible
with all standard disk drives, utilities, applications, memory managers and
caching programs.
Price and Availability
Stacker for Windows and DOS will begin shipping October 30. The suggested
retail price is $149. An upgrade release is available at a suggested
retail price of $49.95 through retail channels and direct from the company.
The upgrade release requires that an earlier Stacker version be previously
installed. Stacker for Windows and DOS version 3.0 is fully compatible
with all Stacker hardware.
