"EVANS & SUTHERLAND BRINGS 3D GRAPHICS EXPERTISE
TO THE PERSONAL COMPUTER

SALT LAKE CITY, March 2, 1995
Evans & Sutherland Computer Corporation (NASDAQ: ESCC) today announced
Freedom Graphics(tm) for the Personal Computer. Freedom Graphics is
the first product to bring the 3D graphics technology of E&S to the
personal computing environment.

Freedom Graphics is an implementation of the specialized features that
3D graphics applications require for smooth, fast execution. Users
can produce impressive realistic images with the product's rich
feature set and high-performance graphics for Windows/NT(r)
applications.

The graphics card supports the OpenGL(r) software application
programming interface and is designed to accelerate OpenGL in the PC
environment. Freedom Graphics is a PCI bus-based card that
incorporates the same technology as the Freedom Series graphics
accelerators which supply high-end graphics for the world's largest
workstation vendors. Ideal markets to take advantage of the extensive
feature set of Freedom Graphics are CAD, Industrial Design,
Simulation, Visualization, Animation, Entertainment and Game
Development. Supported PC processors include MIPS(tm), Pentium(r) and
Power PC(tm).

"The interest being generated by Freedom Graphics is extraordinary,"
said Jim Oyler, President and CEO of Evans & Sutherland. "Freedom
Graphics allows a low-cost PC-based system to achieve the performance
of a much more expensive workstation. This is going to be an
explosive market in the very near future."

Evans & Sutherland is the only 3D graphics vendor with a product line
that spans the entire computing industry from the personal computer up
to multi-million dollar flight simulators and location-based
entertainment systems.

"We are pleased that Evans & Sutherland has applied their knowledge
and experience in high-performance real-time 3D graphics to the PC
marketplace," said Tom Coull, President of Sense8 Corporation.
"WorldToolKit and Freedom Graphics will offer a definitive
hardware-accelerated solution for texture-mapped virtual reality
applications."

Freedom Graphics' feature set includes real-time 3D graphics rendering
and animation, hardware based 24-bit texture acceleration, scalable
texture memory up to 16 MBytes, bi-linear and tri-linear MIP-mapping,
specular highlights, fast set-up calculations, full scene
antialiasing, transparency and depth cueing. The additional
experience of E&S with OpenGL will also result in significant
performance advantages for applications using the OpenGL library from
E&S.

According to Ian Reid, Vice-President of Marketing at Advanced Visual
Systems, "Freedom Graphics offers a new level of capability for the PC
user and AVS/Express allows any PC developer to take immediate
advantage of features such as hardware texture-mapping and
transparency. It's the ideal combination."

Freedom Graphics performance under Windows/NT and OpenGL is 300,000
triangles/second. The card will list price at $2450 with second
quarter availability through OEMs and VARs. Freedom Graphics was
first shown at Fall Comdex '94 in Las Vegas.

The significance of Freedom Graphics lies in its delivery of a
graphics feature set at unsurpassed performance levels. Advanced
features such as texture mapping are still unavailable from any other
vendor for under $10,000. Freedom Graphics also provides performance
not yet seen in the 3D PC graphics market. Nearest competitors for
performance provide minimal feature sets and are only available at
much higher prices.

Evans & Sutherland is a leader in advanced 3D graphics and
visualization systems for science, industry, education, and
entertainment. The Graphics Systems Division provides graphics
hardware and software solutions that are sold and supported by DEC,
HP, IBM, and Sun Microsystems. Evans & Sutherland was founded in 1968
and is based in Salt Lake City, Utah.

Freedom Graphics(tm) for the Personal Computer

High-Speed Realism from Evans & Sutherland

Evans & Sutherland pioneered the computer graphics industry over 25
years ago. Since then our graphics know-how has been engineered into
everything from multi-million dollar flight simulators to high-end
graphics accelerators for workstations. Now, the same technology used
in those high-end workstations is available for the personal computer
with Freedom Graphics. Freedom Graphics is a 3D graphics card that
delivers high-performance, workstation-class 3D graphics for your
Windows NT applications. Freedom Graphics is a masterful
implementation of the specialized features that 3D graphics
applications require for smooth, fast execution. Users will be
impressed by the realistic images they can produce with the
well-crafted feature set.

PRODUCT DESCRIPTION

The Freedom Series graphics from Evans & Sutherland, the world's fastest
graphics technology, is now available on AlphaStation workstations.
Providing both dominating performance, as well as new capabilities, such as
texture mapping in hardware, Freedom Series excels in applications such as
visual simulation, high-end mechanical design and styling, and high-end
geographic information system applications like petroleum reservoir
modeling.

Freedom Series offers raw power plus superb image quality. Advanced graphics
features include anti-aliasing of points, lines, and polygons to eliminate
the stair step raster artifacts. Shaded image display capabilities combine
speed with both shading and lighting models. In addition to doing the
familiar gouraud shading at incredible speed, Freedom Series provides
advanced lighting models for more realistic images. Freedom Series graphics
provides a 24-bit Z-buffer, as well as an 8-bit Alpha buffer to support
transparency effects.

Freedom Series also supports in hardware a technology called texture
mapping. Texture mapping involves taking a texture, such as wood grain,
brick, or even an entire tree, and mapping it onto a surface. Texture
mapping produces extremely realistic images that begin to approach
photorealistic images--images that are indistinguishable from a photograph
of an actual scene. There are several algorithms used for texture mapping.
The simplest algorithms produce raster artifacts, similar to the jaggies
from lines. There are several ways of improving image quality and
performance, and the leading algorithms for this use are tri-linear
interpolation and MIPmapping. Freedom Series graphics supports both of these
capabilities in hardware.

Freedom Series is targeted at the AlphaStation 600 and the AlphaStation 250
systems. On the AlphaStation 600, Freedom Series uses the PCI64 bus to
provide a full 64-bit high bandwidth interface between the AlphaStation and
the Freedom Graphics module. The Freedom Series graphics also supports the
standard 32-bit PCI interface used on the AlphaStation 250.

Features of the Freedom Series include:

* Extremely high performance
