FDD Connector (CN4)
You can attach up to two floppy disks to the PCM-6892's on-board
controller and use any combination of 5.25" (360 KB and 1.2 MB)
and/or 3.5" (720 KB, 1.44 MB, and 2.88 MB) drives.
The PCM-6892 CPU card comes with a 34-pin daisy-chain drive
connector cable. On one end of the cable is a 34-pin flat-cable
connector. There are two sets of floppy disk drive connectors, one
in the middle, and one on the other end. 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).
