Floppy disk drive on LPT1
The LPT1 parallel port can also be used as a floppy disk drive port. Octagon has a
2060 LPT-to-Floppy Adapter cable (part #6470) that plugs into the LPT connector
on the 2060 HDC-18-SBC-Multiport cable, and provides a standard 34-pin
connector on the other end. Table 6–2 shows the wiring diagram of the 2060 LPT-
to-Floppy Adapter cable.
Note that only the LPT-to-Floppy cable part # 6470 can be used with this card, as
the floppy pin out from the LPT port differs from other cards.
