I only saw the cassette ports (next to the keyboard ports) on the very
early IBM PC's which were generally the ones that were shipping I think
with only 64K installed. Then the later shipped IBM PC's with fully
installed memory no longer had the cassette ports (some of the cases had
a plastic cover over the port, then the cases completed had the cassette
port hole omitted completely and that was it on those...

Most PS/2 machines have it. Only the absolute latest ones, like the

think it only disappeared completely when IBM stopped using BIOS that
were written specifically for each machine and moved to something
"standardized".
They don't have the cassette port, though, of course.

ROM BASIC is present on the PC, XT/Portanble and AT at least. I have
no idea if it was fitted to any PS/2 machines. Could you elaborate? I've never found a

Including ROM BASIC that writes
and reads cassette tapes?
