IBM Personal System/2 Model 80

General information
Machine type: 8580
Announce date: April 2, 1987

Excerpt from the original announcement letter;

"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."
