In the US, IBM NEVER sold a cassette cable. But the pinout was the same
as the TRS-80 1 and 3.

Radio Shack here used to say that THEIR cassette recorder (CTR-80?) was
the best for it, and the only one that would work reliably. Their
explanation was that it wouldn't work right with a higher fidelity, that
it needed the amount of "blur" of the signal that theirs did!

I always found the TRS-80 cassette to be an almost entirely WRITE-ONLY
medium. Success with reading back tapes was as elusive as successful CD
burning with the eatly 2X CDRs.

There was once an outfit that marketed a PC to PC communications package
through the cassette ports. That died immediately on release of the XT.
There had been similar stuff with Coco.
