AST RESEARCH ANNOUNCES FIRST 386SL NOTEBOOK COMPUTER WITH BREAKTHROUGH
TECHNOLOGY FOR COMPLETE SYSTEM UPGRADEABILITY

Upgradeability and PCMCIA Slots Equip Next Generation Notebook for
Limitless Computing

Irvine, Calif., September 21, 1992 -- AST Research Inc., the pioneer in
upgradeable personal computers and manufacturer of the award-winning
Premium Exec notebook, today announced the PowerExec, a fully upgradeable
386SL notebook computer that provides up to six and one-half hours of
battery life through integrated "intelligent" power management.

Prominent innovative features of the AST PowerExec include:

* Upgradeable processor to 32-bit/3 volt 486 processor

* First upgradeable display to ultra STN color and/or TFT active matrix
color

* Two Type II industry-standard PCMCIA slots provide increased flexibility
and expansion capability

* Optional AST SmartPoint cableless trackball pointing device connects to
built-in hot shoe which is ergonomically-designed into the front of the
keyboard

* Monochrome model 123W (120-MB hard drive) and passive color model 163W
(160-MB hard drive) come standard with Windows 3.1 and SmartPoint
cableless trackball

* Battery life of up to 6.5 hours with 90 minute recharge

* Supports optional Alkaline batteries which can provide an additional 1.5
hours of battery life

* Heuristic Algorithms provide breakthrough intelligent power management
features that adapt to the user's work habits

* Removable hard drive provides data security, flexibility of multiple hard
drives and easy hard drive upgrades

The PowerExec 3/25SL runs at 25-MHz and combines next-generation
technology, complete system upgradeability, intelligent power management,
and absolute value that provide maximum usability to the end user. The
PowerExec notebook is available with a monochrome or color display.

"What the PowerExec offers is a complete notebook solution with
upgradeability and intelligence built in to protect the end user's
investment," said Dan Sheppard, director of portable systems marketing.

First Notebook to Offer Upgradeability to 3 Volt 32-Bit 486 Processors and
Active Matrix Color Displays

PowerExec represents a new generation of notebook computers. The system's
processor board is easily upgradeable to higher-performance 486 32-bit
processors with 3-volt technology for longer battery life. "The ability to
upgrade provides increased performance when needed and insurance for users
concerned about quickly changing technology," said Sheppard.

Another upgradeable feature is the PowerExec's LCD display. The 9.5-inch
monochrome display is easily upgradeable to either 9.5-inch F-STN passive
matrix color or available in Q4, 9.5-inch TFT Active Matrix color. The end
user who initially selects the passive color display may also upgrade to
the new 9.5-inch Active Matrix when available.

PowerExec's passive color display offers improved contrast over first
generation color notebooks as well as enhanced viewing angle and increased
brightness to provide an affordable alternative to TFT Active Matrix
color.

AST's new Flash BIOS provides a fast and convenient way to upgrade the
notebook's firmware. End users can now be up and running quickly with new
BIOS enhancements.

The First Notebook to Feature Two Industry-Standard Slots

The PowerExec features two, Type II PCMCIA Expansion Slots. PCMCIA is the
new industry standard for portable computer expansion and connectivity
solutions which opens up the architecture of the notebook computer and
offers innovative options not offered with proprietary expansion slots.
Similar to desktop ISA boards, PCMCIA credit card-sized cards offer a
variety of options to allow end users to customize their PowerExec. For
instance, the increased flexibility provided by the two slots allows end
users to configure their notebooks with a modem and SCSI adapter while on
the road or a modem and networking card while in the office. AST offers
PCMCIA compatible networking options including Token Ring and Ethernet, as
well as a SCSI adapter and three modem options.

The First Notebook to Provide Up To Six and One-Half Hours of Battery Life

Longer battery life is a result of improved battery design, system design
and power management. The PowerExec's Nickel Metal Hydride battery pack,
more efficient backlight and power supply designs, the use of lower-power
components and a host of intelligent power management features, allow the
PowerExec to offer exceptionally long battery life from a notebook
computer weighing less than six pounds. At up to six and one-half hours,
the PowerExec provides substantial battery life which exceeds that of many
competing notebook computers.

AST SmartSleep, an enhanced suspend state, functions as a bookmark by
saving a mirror image of memory to the hard disk drive and automatically
shutting off the system. When the user resumes working, he will return via
a quick-boot to the exact point of activity when the system was shut off.
Most importantly, SmartSleep functions within all operating environments
such as DOS, Windows, and OS/2, for instance.

With four to six and one-half hours of battery life, there is less need for
the end user to carry a spare battery, reducing the total travel weight of
the system to 7.3 pounds, compared to 8.6 pounds for the Compaq LTE
Lite/25 with an extra battery. Total travel weight includes an AC adapter
and power cord.

The notebook also provides PowerCharge, a "quick charge" of the battery in
merely 90 minutes. The real breakthrough is the intelligent "power-on"
charging or SmartCharge which allows the notebook to divert power that
isn't being used by the system's components to the charging circuitry,
providing an extremely rapid charging time of two to three hours with the
system on. This compares to older technology notebooks which required a
charge of up to 16 hours.

For emergency use, the notebook can be operated using 12 AA alkaline
batteries providing up to one and one-half hours of battery life. A
convenient on-screen fuel gauge, built into the BIOS, gives the user an
accurate display of battery usage.

HotSwap feature allows the user to exchange the system battery with the
system turned on in the suspend mode, without losing any data.

The First Notebook to Conserve Battery Life by Learning and Adapting to
User's Work Habits 

The PowerExec uses heuristic algorithms to monitor the user's work habits
to learn when to power-off idle peripherals, conserving battery life.
Whenever there is keyboard inactivity, hard disk drive and display "time
outs" are activated. The system goes back to full-power mode once work
resumes. In this sense, the PowerExec is the only notebook computer
capable of adjusting its performance based upon what it has learned.

Multiple Levels of Anti-Theft Security Render the PowerExec Useless if
Stolen

The PowerExec is the only notebook computer which becomes unuseable if
stolen. AST provides the ability to establish two unbreakable passwords,
one for the end user and another for an MIS administrator. For ultimate
protection, AST has eliminated any "hidden" overrides to password
protection. There are no hardware jumpers in the system to disable
password protection. AST supplies a specially designed ROM security key,
SmartKey, with each PowerExec which functions as a third password.

The PowerExec is designed to support the Kensington Microware cable lock
for added physical security. For added security, the PowerExec also locks
into the PowerStation docking station with a key lock.

Removable Hard Drive Provides Increased Functionality for the End User

Another innovative feature that the PowerExec offers is the removable hard
drive. This feature allows the end user to easily upgrade the system to a
larger hard drive whenever necessary. The benefit of added security by
removing and storing the hard drive, as well as the flexibility of
unlimited space by using multiply hard drives to store software programs
and data are provided to enhance the PowerExec's usability. The end user
has the convenience of removing and retaining the hard drive during
service.

Fast and Convenient Data Exchange with Desktop Computers

An innovative drive bay adapter designed by AST, allows any desktop
computer to accept the PowerExec's removable hard drive making data
transfer easy and convenient. The receptacle fits into one 5.25-inch
half-height drive bay. The PowerExec provides an expansion bus connector
that supports AST's PowerStation and EasyPort.

Innovative Quick-Connect and Docking Station Options Enhance the
PowerExec's Usability

The PowerStation docking unit offers a complete connectivity solution for
mobile professionals who require the ease-of-use of one computer.
Affordably priced at $449, the PowerStation combines the flexibility of
notebook computing with the familiarity of traditional desktop computing.

The PowerStation features two ISA 16-bit slots and provides access to one
5.25-inch drive bay and one slimline 5.25-inch drive bay for extra
storage, as well as a drive bay with a tape backup device. The
PowerStation features a monitor stand that can accommodate high-resolution
monitors weighing up to 70 pounds.

The EasyPort provides an ideal solution for the end user who requires the
convenience of a notebook at home and in the office. With an affordable
suggested list price of $99, the EasyPort replicates the ports of the
PowerExec enabling quickconnect funtionality without the need to hook-up
power and port cables.

The PowerExec features a choice of hard drives to suit the end users
particular computing needs. Standard monochrome models are the PowerExec
3/25SL Model 63 (60-MB hard drive) list priced at $2,395 and 3/25SL Model
123/W (120-MB hard drive and bundled with Windows 3.1 and AST SmartPoint
trackball) with a suggested retail price of $2,795. Standard color models
are the PowerExec 3/25SL-Color Model 83 (80-MB hard drive) with a list
price $3,495 and 3/25SL-Color Model 163/W (160MB hard drive and bundled
with Windows 3.1 and AST SmartPoint trackball) retail priced at $3,895.
All models come standard with DOS 5.1.

"We expect street prices for the PowerExec to be competitive with those of
direct marketers who are still offering first-generation technology,"
Sheppard said.

The anticipated street price may range from under $2,100 for the PowerExec
3/25SL Model 63 to slightly above $2,400 for the 3/25SL Model 123/W. The
expected street price on the color models may range from under $3,100 for
the PowerExec 3/25SL-Color Model 83 to under $3,400 for the 3/25SL-Color
Model 163/W.

Both monochrome and FSTN color PowerExecs are available in Model 3 (no hard
drive) configurations and can be purchased by resellers with a choice of
60MB, 80-MB, 120-MB or 160-MB hard drives to customize the units.
