You can attach up to two floppy disks to the PCM-5890's on-
board controller. You can use any combination of 5¼" (360 KB
and 1.2 MB) and/or 3½" (720 KB, 1.44 MB, and 2.88 MB) drives.
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 3½" drives) and a printed-circuit board connec-
tor (usually used for 5¼" drives).
1. Plug the 34-pin flat-cable connector into CN14. Make sure
2. Attach the appropriate connector on th eother end of the cable
3. If you are connecting a 5¼" floppy drive, line up the slot in the
If you need to make your own cable, you can find the pin assign-
ments for the card's connector in Appendix C.

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. Also,
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 sesire, connect the B: drive to the connectors in the
middle of the cable as described above.
