IBM PS/2 (Model 57 SLC) - Technical specifications


IBM Personal System/2 Model 57 SLC

Inside the 8557slc

General information
Machine type: 8557
Announce date: February, 1992

Excerpt from the original announcement letter;
"PS/2 Model 57 SLC complements and enhances the PS/2 family of Micro Channel systems with the integration of the IBM 386SLC 20MHz microprocessor which includes 8K of internal cache as well as the internal cache controller. The PS/2 Model 57 SLC system offers up to 88% performance improvement over the 57SX. Also included are a fixed disk drive, a 2.88MB media sense diskette drive, 16-bit video graphics array (VGA), a small computer systems I/O interface (SCSI) and 4MB of memory housed in the same versatile 5-slot/4 bay mechanical package as the IBM PS/2 57SX. Two models (8557-055 and 8557-059) are offered with disk capacities of 80MB (Million Bytes) and 160MB (Million Bytes) respectively. The system is designed to allow the flexibility of horizontal or vertical operation and ships with a stand which is required for use in the vertical orientation. Five 16-bit Micro Channel slots allow users to expand and customize system function. A fixed disk and diskette drive are installed in each system and two expansion bays are available to accept additional 5.25-inch and/or 3.5-inch diskette drives, fixed disks, tape, CD-ROM or other devices. The SCSI controller is integrated in the planar, therefore no slot is required to attach up to seven SCSI devices (including the standard fixed disk). Two additional SCSI devices may be installed internally and the remainder externally via the external connector. "
