The tape drive was actually a useful idea, which should have been continued
all the way throughout the PS/2 line. It allowed whoever was using the
computer to actually make use of the ROM BASIC. The floppies aren't
available in ROM BASIC, and once a program is typed in, there's no way to
save it. The cassette drive worked in the same way that the cassette drive
in TRS-80's did. It acted as the storage device in ROM BASIC. In fact, I
don't even think the PC came with a cable to connect it to a tape deck. You
had to run down to RadioShack and pick up a TRS-80 cassette cable.
I think I actually have an entire 60-minute tape full of PC-BASIC programs
(somewhere). I think one of the not-so-smart things that IBM did was to
remove the cassette interface and to keep the now-useless ROM-BASIC in
there.
