I never saw anybody use the cassette port for practical
purposes. In fact, I
never saw a cassette drive from IBM. Good trivia question. Has anybody >ever
seen one? I do remember reading something years ago about hobbyists >using
the cassette port for plugging in wierd hardware hacks.
I don't think IBM would have made cassette recorders.
IBM made a cassette adapter cable for the IBMPCjr, but I don't think
one was ever made for the PC.

The orignals were lower density like 320k each at first
but quickly
gone after XT came out with standard 360k drive or two, or floppy and
10mb HD.
It was DOS 2.0 that increased the formatted capacity from 320K to 360K.
