2.16 Floppy Drive Connector (CN3)

With two options on floppy drive you could simply adopt any of the combinations
of 5.25" (360 KB and 1.2 MB) and/or 3.5" (720 KB, 1.44 MB, and 2.88 MB)
drives onto the mainboard.
A 34-pin daisy-chain drive connector cable is required for a dual-drive system. On
one end of the cable is a 34-pin flat-cable connector. On the other end are two
sets of floppy disk drive connectors. Each set consists of a 34-pin flat-cable
connector (usually used for 3.5" drives) and a printed-circuit board connector
(usually used for 5.25" drives).
Wire number 1 on the cable is normally red or blue, and the other wires are usually
gray.
Connecting the floppy drive
1. Plug the 34-pin flat-cable connector into CN3. Make sure that the red or blue
wire corresponds to pin 1 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 5.25" 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 3.5" floppy drive, you may have trouble
determining which pin is pin number 1. Look for a number printed on the circuit
