Hi,

Does anyone have technical information of the IBM cassette tapes
used to load diagnostic programs in systems like the IBM System/7,
IBM System/3 and the original IBM PC 5150 ?

I am looking for the used frequencies (fsk), the data speed,
the format, etc etc.

Thanks for all your replies.

Regards
