IBM PS/2 (Model 50) - Technical specifications
Applicable to: World-Wide
IBM Personal System/2 Model 50
General information
Machine type: 8550
Announce date: April 2, 1987
Excerpt from the original announcement letter;
"The Personal System/2 Model 50 (IBM 8550) introduces advanced design and technology and a new MICRO CHANNEL (TM) ARCHITECTURE to provide significant price/performance enhancements for desktop computing and workstations. The 10MHz INTEL 80286 microprocessor offers application growth capabilities and is designed to maintain software compatibility with most current IBM personal computer programs. A high level of feature integration on the system board reduces optional adapter requirements. When configured with the new analog displays, the IBM 8550's new integrated Video Graphics Array (VGA) provides enhanced performance, increased display functions, and increased color availability. The system includes a 1.44MB, 3.5-inch diskette drive and a 20MB fixed disk drive. Besides the new mouse, memory, math co-processor, and diskette drive options, new connectivity options (dual asynchronous, multi-protocol, and modem adapters, and other options) allow the IBM 8550 to communicate with a variety of hosts and networks."
