It would also be interesting to know how many were turned out and by
who. It was easy to produce a few cassettes, just put up a bank of
them, hit record and wait till the beep or whatever at the end.
However turning out just a few from a commercial cassette operator would
be a challenge. I know out here in Irvine, Panasonic had a mastering
operation. They would use 10 or 12' diameter platters or reels of raw
tape material, and master all of them with a special heating process @
200ips.
The masters would then be put into a machine which could fill cassettes
and also sense electronic markers showing where the images were on the
full reel. I don't know how you'd get fewer than a 1000 from them.

I didn't know that -
I have IBM Diagnostics on Cassette tape that came with the machine.
I just found it strange that the diagnostics would come on cassette tape
but there was never an IBM cassette player. I guess there really was
a plan...

Well, what tape reader was 5150 compatible?
Just about any inexpensive audio cassette recorder. I used a cheap
one with the GE brand on it. AFAIK, IBM did not offer a connecting
cable between the 5 pin DIN and a recorder, but the one offered by
Radio Shack for its own machines worked just fine.
