4.12 Parallel Interface LPT
The parallel interface is a standard IDC socket connector with a spacing of 2.54 mm. The port address
and the interrupt are set via the BIOS setup.
The parallel port may be selected in BIOS-setup to interface to a standard PC floppy drive, but a special
cable is required for such operation. Please contact your sales representative for such a cable.
