190-057 IBM PERSONAL SYSTEM/2 MICRO CHANNEL SCSI ADAPTER WITH CACHE
       The PERSONAL SYSTEM/2 MICRO CHANNEL SCSI ADAPTER WITH CACHE is
a 32-bit bus master adapter that provides expandability for all
Personal System/2 (R) (PS/2 (R)) Micro Channel (TM) Architecture
systems.  This Small Computer System Interface (SCSI) adapter can be
installed in either a 16- or 32-bit card slot, has a 16.6MB burst
transfer rate, 512KB Cache buffer, and adheres to the Small Computer
System Interface (SCSI) that supports connection for multiple
internal and/or external SCSI devices.  These devices include SCSI
high performance fixed disk drives, scanners, CD-ROM drives, and
other SCSI peripherals.
       The PS/2 MICRO CHANNEL SCSI ADAPTER EXTERNAL TERMINATOR is a
plug required to terminate the SCSI bus at the external port on the
SCSI adapter.  The external terminator is installed at the SCSI
adapter port when no external SCSI devices are attached.
       STATEMENT OF DIRECTION:  IBM intends to support the PS/2 Micro
Channel SCSI Adapter with Cache in the PS/2 Models 8555 (061), 8565,
8570, 8573 (061 and 121) and 8580 by the AIX (R) PS/2 operating
system.
