Standard Configuration

Your system is cabled using a dual channel on-board IDE Controller
and dual on-board Symbios Logic SYM53C875 SCSI Controllers. The
on-board IDE controller supports the internally mounted CD-ROM as
its first (master) device and an optional internally mounted IDE tape
drive as its second (slave) device.
Controller A of the SCSI controllers attaches to a 68-pin 16-bit (wide)
SCSI connector interface and is capable of supporting a maximum of
four 1-inch high SCSI Ultra-wide hard disk drives or three 1.6-inch
high SCSI Ultra-wide hard disk drives. Controller B attaches to a 50-pin
8-bit (narrow) SCSI connector interface capable of supporting two SCSI
5.25-inch removable media devices.
Also, a 3.5-inch diskette drive is installed in all systems and interfaces
separately to the system board.
Referring to the Figure below, a 68-pin wide SCSI interface cable (C) is
connected to the SCSI connector (D) in the lower middle of the system
board. This cable connects to the rear of the hard disk drives (B). A
terminator (A) must be plugged into the end of this SCSI cable.
The IDE interface cable (I) is connected to the IDE connector (H)
towards the right edge of the system board. This cable connects to the
rear of the internally mounted CD-ROM drive (J).
Two optional internally mounted SCSI removable media devices (M) may
be connected to the SCSI controller connector (K).
