ALLIANCE PROMOTION FAMILY NOW SUPPORTS STEREOGRAPHICS SIMULEYES VR 3D
EYEWEAR

High-Performance 3D Graphics on Home PC Made Possible by ProMotion

San Jose, CA -- February 12, 1996 -- Alliance Semiconductor Corporation
announced today that its ProMotion graphics and video accelerators will
support StereoGraphics Corporation's latest stereo vision eyewear product,
SimulEyes VR for multimedia programs and games on home PCs. 

Alliance now provides a reference design for a ProMotion-based Multimedia
User Interface (MMUI) adapter card with direct support for StereoGraphics
eyewear. In addition, SimulEyes VR-ready ProMotion accelerators are
sampling now to OEM graphics hardware suppliers. 

SimulEyes VR stereo vision eyewear transforms home multimedia PCs into
stunningly realistic 3D environments with eye-catching visual effects by
adding true depth perception for game play. SimulEyes VR eyewear fits over
most glasses for maximum comfort, weighs only a few ounces and is simple
to install. 

While SimulEyes VR is designed to operate with a variety of different
graphics accelerators, the direct-connect reference design will allow a
ProMotion and SimulEyes VR combination to be less expensive than one based
on an ordinary graphics controller. 

"The movement in the PC graphics industry to integrate stereo vision
support in silicon will facilitate unparalleled realism in 3D games and
multimedia software at an affordable consumer price," said Dick Martin,
StereoGraphics' president and CEO. "Alliance's feature-rich ProMotion
accelerator family with built-in SimulEyes VR support will help establish
stereo vision as a mainstream feature in PC systems." 

"Graphics adapters which combine Alliance's ProMotion acceleration with the
SimulEyes VR system will make for stunning stereo vision 3D gaming on
standard PCs," said Sid Agrawal, Alliance's vice president of marketing.
"ProMotion's high-performance, low-cost graphics and game acceleration is
an ideal partner to StereoGraphics' 3D eyewear." 

ProMotion Graphics and Video Accelerators

Alliance's ProMotion family of graphics and video controllers are
high-performance, integrated Windows accelerators with built-in hardware
acceleration for MPEG-I motion video playback and scaling. ProMotion
controllers are designed to seamlessly accelerate graphics and multimedia
applications under Windows 95, Windows 3.x and other operating
environments. 

ProMotion controllers support high resolutions and refresh rates for
displays of up to 16.7 million colors. They feature PCI Local Bus host
interface, and support for I to 4 megabytes of DRAM memory. Even with only
1 megabyte of display memory, ProMotion controllers can accelerate
full-screen, 1024x768x8-bit or 800x600x16-bit graphics and motion video
playback.
