Chapter 2 Installation Guide 23
Connecting the floppy drive
1. Plug the 34-pin flat-cable connector into CN10. Make sure that
the red wire corresponds to pin one on the connector.
2. Attach the appropriate connector on the other end of the
cable to the floppy drive(s). You can use only one connector
in the set. The set on the end (after the twist in the cable)
connects to the A: drive. The set in the middle connects to the
B: drive.
3. If you are connecting a 5¼” floppy drive, line up the slot in
the printed circuit board with the blocked-off part of the cable
connector.
If you are connecting a 3½” floppy drive, you may have
trouble determining which pin is pin number one. Look for a
number printed on the circuit board indicating pin number
one. In addition, the connector on the floppy drive connector
may have a slot. When the slot is up, pin number one should
be on the right. Check the documentation that came with the
drive for more information.
If you desire, connect the B: drive to the connectors in the
middle of the cable as described above.
If you need to make your own cable, you can find the pin assign-
ments for the board’s connector in Appendix B.
