The Personal System/2 Model 80 (IBM 8580) enhances the System/2 family
of systems by offering a new level of performance in personal computing
for both commercial and compute-intensive environments.
This system is highlighted by the new MICRO CHANNEL(TM) ARCHITECTURE
with a 16 MHz 80386 32-bit microprocessor, high density memory technology,
and a wide range of integrated features.
With the capability of supporting up to 16 Mb of high speed (80 ns)
real memory, over 140 Mb of disk storage, advanced graphics, and an
optional 16 MHz 80387 Math Co-Processor, this system opens up a wide
range of application opportunities.
Designed to meet the requirements of the multitasking environment,
the IBM 8580 provides a full 32-bit large system architecture and function
within an individual workstation.
Its increased speed and high reliability coupled with a wide selection
of connectivity options provide the function required to support large
server, gateway or multiuser applications.
