Well, what
tape reader was 5150 compatible?
Just about any cheap mono audio cassette recorder?
The pinout of the IBM cassette socket was (as Fred said) the same as the
TRS-80 Model 1 (and Model 3, Model 4, CoCo, M100, M200, etc). You could
use the Radio Shack cable which had a 5 pin DIN plug on one end (to fit
the computer) and 3 jack plugs (phone plugs to you?) on the other. One
for the remote control, one for singnal from the computer to the tape,
the last for the signal from the tape to the computer.
Is this cable still
available somewhere?
I'd like to test cassette support on my 5150 and take some
screenshots...
