Radius Announces First 24-Bit, Accelerated Display Interface for New Apple
Macintosh Centris Computer 

First fully featured 7-inch graphics display interface works with all NuBus
Macintosh Computers

SAN JOSE, Calif., February 9, 1993 -- Radius Inc. (NASDAQ-RDUS) today
announced two new PrecisionColor interfaces for Apple Macintosh computers
that provide fully featured graphics display functions in a 7-inch
NuBus-sized card. The new cards provide full 24-bit video and graphics
acceleration at a variety of resolutions and are the first to conform to
the 7-inch NuBus form factor first used on the Macintosh Centris 610
computer system from Apple Computer, Inc..

This new space saving form factor requires a smaller NuBus card than any of
those currently on the marketplace. Radius' new PrecisionColor interfaces
also use less power and produce less heat than conventional cards.

"Apple continues to innovate computer platforms with the introduction of
new machines including the Macintosh Centris 610, which requires a smaller
NuBus card size," said Mary Coleman, Radius vice president of marketing.
"Our advanced ASIC design has allowed us to pack all the performance of an
accelerated 24-bit video card into this new form factor, delivering
photorealistic display capabilities to users of both current and future
Apple systems. These new interfaces save space within the computer,
require less power for operation and run cooler than any other card
available with their capabilities."

Specific features of the new cards include:

* 24-Bit Color -- Displays up to 16.7 million colors on-screen for stunning
photo-realistic images.

* Complete NuBus Compatibility -- The PrecisionColor boards work with all
Apple Macintosh, Macintosh Quadra, and Macintosh Centris computers with
NuBus expansion capability.

* Instant Resolution Changing -- "On-the-fly" resolution switching allows
640x480 detail or 1152x870, 2-page viewing with a single mouse click.

* Universally Compatible -- Support for virtually any 14-inch to 21-inch
monitor at resolutions ranging from 640x480 to 1152x870 with minimum
screen flicker and highest quality image.

* On-Board Acceleration -- Custom ASIC circuitry accelerates commonly used
QuickDraw functions to enhance screen performance many times over
non-accelerated graphics boards.

* System Performance Acceleration -- Provides major system performance
improvements when used in tandem with the Radius Rocket accelerator by
providing display-list processing, CPU and graphics acceleration, as well
as QuickDraw acceleration.

Price and Availability

The PrecisionColor interface cards are scheduled to be available starting
March 1, 1993. The PrecisionColor 24X/1152, which provides display
resolutions of up to 1152x870 carries a U.S. list price of $1849, while
the PrecisionColor 24XK/1024, supporting resolutions of up to 1024x768,
