Figure 3-9 System Board Cable Connectors

Diskette Drive Signal Cable

A two-connector diskette drive signal cable comes attached to the system board and to the
standard 1.44-MB diskette drive. A three-connector cable is required for adding a second
device.

The colored edge of the cable goes to pin 1 on the cable connector. Align the red edge of
the cable with pin 1 (the notched end) on the drive connector.
