This connector is for the provided floppy disk drive (FDD) signal cable. Insert
one end of the cable to this connector, then connect the other end to the
signal connector at the back of the floppy disk drive.
Pin 5 on the connector is removed to prevent incorrect cable connection when
using an FDD cable with a covered Pin 5.

The LPT (Line Printing Terminal) connector supports devices such as a
printer. LPT standardizes as IEEE 1284, which is the parallel port interface on
