190-056 IBM PERSONAL SYSTEM/2 MICRO CHANNEL SCSI ADAPTER
       The PERSONAL SYSTEM/2 MICRO CHANNEL SCSI ADAPTER is a 16-bit
Micro Channel (TM) bus master adapter that provides expandability for
all Personal System/2 (R) (PS/2 (R)) Micro Channel (TM) Architecture
systems.  The Small Computer System Interface (SCSI) adapter provides
connection for multiple internal and/or external SCSI devices and has
a 8.3MB per second Micro Channel burst transfer rate.  The adapter
card may be installed in a 16- or 32-bit card slot and provides the
ability to connect SCSI high performance fixed disk drives, scanners,
printers, CD-ROMs and other SCSI peripherals.
       The IBM PS/2 CARD TO OPTION CABLE provides the capability to
attach the first external SCSI device to the Micro Channel SCSI
adapter.  The PS/2 Micro Channel SCSI Adapter Option Interface
Terminator, included with the PS/2 Card to Option Cable, is a
terminator that is installed on the last SCSI device to terminate the
SCSI bus.
       The IBM PS/2 OPTION TO OPTION CABLE is a standard SCSI cable
that provides the capability to attach an external SCSI device to
another external SCSI device.
       STATEMENT OF DIRECTION:  IBM intends to support the PS/2 Micro
Channel SCSI Adapter in the PS/2 Models 8555 (061), 8565, 8570, 8573
(061 and 121) and 8580 by the AIX (R) PS/2 operating system.
