Standard Configuration

Your system is cabled using a dual channel on-board IDE
Controller and dual on-board Symbios Logic SYM53C876
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).
