the IBM PC itself or was it a diagnostic tape for a tape drive??? I have
several diag tapes for the Atari 410 which test the alignment and speed of
the Atari 410 tape drives, so this is why I ask.
It is diagnostics for the PC.
Almost, or maybe exactly, the same as the diagnostics on disk.
I have never seem the "Advanced Diagnostics" on tape, but have been told
that it existed.
Perhaps the reason that nobody is familiar with the IBM cassette drive
might be because there never was one?
But the PC DID come with a diagnostics tape. It was simply assumed that
the tape drive would be user provided. That way IBM was off the hook when
it didn't work.
