A somewhat 'crude' but simple thing you can try is to listen to the
audiotape sound of the tape you created which you say was successful.
Then listen audibly to the tapes you're trying to recover. If the pitch
seems to match for the most part it isn't a speed problem. If you have
an oscilloscope, look at the amplitude of the signal out of the cassette
drive of the new 'working' tape and compare to the one you're trying to
I haven't done this, but there are decent tools nowadays for what could
be called 'high performance audio editing' that you can throw at the
problem, if you use your sound card to digitize the audio to a WAV file.
I use Cool Edit 2000 (much less expensive than full-bore Cool Edit,
probably no longer available) for audio work. There are a LOT of
powerful tools for fiddling with audio now that we have all the
horsepower for DSP that a modern pee-cee provides.
Somebody should develop an 'audio datacassette emulator' for the kind of
thing you're trying to do. I have a T/S 1000 that I'd use more if I had
something like that to use with it. Ideally it would even have a
'remote on' input, i.e. the TRS-80 Model 1 could turn the drive on and
