Industry Standard Interface (non-SCSI)
The computer interface will consist of either two cables with a 50-pin card edge
connector on each, or a single cable branching out into two 50-pin card edge
connectors. The card edge connectors must be connected to J1 and J2 at the rear of
the tape drive (sometimes referred to as J101 and J102 respectively). Connector
locations are shown in Figure 1-10.

There are three removable cable entry covers attached to the rear chassis panel
with two Phillips screws each.

When using a round interface cable, remove all cable entry covers, pass the
cable through the upper opening and attach the connectors to the PCBA. Then
replace all three cable-entry covers, routing the cable through the slot in the
upper cover.

When using flat ribbon cables, remove and store the two lower cable entry
covers. The upper cable entry cover remains in place.

Connect the cables to J1 and J2 as shown on the decals.
NOTE
Be sure to turn the tape drive off before attaching the interface cables.
