2.2 Floppy Drive Connector (CN3)
You can attach up to two floppy disk drives to the PCA-6181's
onboard controller. You can use any combination of 5.25" (360 KB / 1.2
MB) and/or 3.5" (720 KB / 1.44/2.88 MB) drives.
The card comes with a 34-pin daisy-chain drive connector cable. 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). You can use
only one connector in each set. The set on the end (after the twist in
the cable) connects to the A: floppy drive. The set in the middle
connects to the B: floppy drive.
2.3 Parallel Port (CN4)
The parallel port is normally used to connect the CPU card to a printer.
The onboard parallel port can be accessed through a 26-pin flat-cable
connector, CN4. The card comes with an adapter cable which lets you
use a traditional DB-25 connector. The cable has a 26-pin connector on
one end and a DB-25 connector on the other, mounted on a retaining
