Section 1 Abstract
Silicon Graphics designs, manufactures, and markets computational systems used by
engineers, scientists, and animation professionals for design and analysis of 3D
objects and for general-purpose technical computing.  By employing RISC technology
and proprietary VLSI components to provide both high-performance computing and
high-performance graphics, Silicon Graphics continues to deliver the most powerful
systems for engineering and scientific applications.

1.1 The POWER Series(tm) Systems

POWER Series systems are available in four categories:

o   POWER Station(tm) servers use advanced processor technology from Silicon

o   IRIS PowerVision(tm) systems combine the same POWER Series parallel processing
     technology with the revolutionary VISION graphics subsystem.

o   IRIS RealityEngine(tm) Systems offer parallel CPU technology and the most
     advanced interactive graphics in the world.

o   POWER Center Servers and graphics systems provide the most expandable
     packaging for server and graphics applications.

Combining up to 15 new, proprietary VLSI parts with the innovative POWERpath
architecture allows the POWER Series to increase dramatically both the compute
power and graphics available in deskside systems.

Any Silicon Graphics IRIS-4D(tm) super workstation may be upgraded to any POWER
IRIS system with the fully compatible 4D/VGX or 4D/RealityEngine upgrade.  The
33 MHz multiprocessor and 40 MHz CPU subsystems may be combined without
restriction.  The standard configuration CPU subsystems include any one of the

o   One 33 MHz RISC processor and one floating point coprocessor

o   Two 33 or 40 MHz RISC processors and two floating point coprocessors

o   Four 33 or 40 MHz RISC processors and four floating point coprocessors

o   Eight 33 or 40 MHz RISC processors and eight floating point coprocessors

All POWER Series systems also include a fully semaphored, threaded UNIX(R)
(IRIX(tm)) kernel and:

o   8-256 MB ECC memory

o   320 MB-27.3 GB formatted disk capacity
