Follow these steps to connect the cables:
1. If you are installing a diskette or tape drive, go to step 2. If
you are installing a hard disk drive, skip to step 3.
2. Locate the diskette drive ribbon cable. (One end is connected
to the main system board and the other end,
labeled FDD 1,
is attached to the top diskette drive.) To connect diskette
drive B, use the connector
labeled FDD 2.
To connect a tape
drive, use the connector labeled
TAPE DRIVE ONLY.
The interface extending from the back of the drive has
gold contacts on both sides. Align the cable connector with
the interface so that the plastic divider on the connector
lines up with the gap in the interface, as shown below.

Make sure the connector fits properly onto the drive interface
and then push it into place. Then go to step 4.
Caution
If you do not align the connector correctly, you could
severely damage your diskette drive when you push it in.
