Mike Haas and I had both been over this guys stuff at least three times then I decided to go through the stuff one more time while Mike went and got the car. That's when I found the VIP. Needless to say, Mike was quite upset! It's amazing how many times you can look through the same stuff and still find something that you previously overlooked.

It would probably work. I have a few KIM-1 cassette
programs
(most at 3x normal speed) posted as WAVs at
http://www.learnmicros.com. (And a few songs that KIM sings
too,
also as WAVs.) :)
This seems to be 100% reliable once you get the levels
right.
As an aside, none of those recordings came from a recorder,
but
directly from a "C" program which generated the WAV samples.
Probably the worst case would be you'd need an RC low-pass
filter between the playback device and your cassette input,
to simulate the low-pass characteristics of a voice-grade
tape recorder.
Undoubtedly, you'd have to experiment with the sample rate
and stuff. I found 16 Khz mono with 8 bit samples works
fine
for KIM at 3x speed (half-hypertape.) I couldn't figure out
how to generate half a wave in my "C" program, so I stopped
at 3 x normal speed. Hypertape's still da fastest for KIM.
