I ran across a Advanced Diagnostics cassette tape for an IBM PC 5150.
I've never seen such a thing before. Besides the obvious
cassette-to-cassette copy (which I'm not equipped to do), how else would
one preserve this? A WAV file?

Might be worth seeing what the 8-bit Micro folks use. My thought is hook a
good cassette deck up to a PC soundcard. Obviously MP3 would be a bad file
choice :^)
:-) But that's exactly what I've done and seen others done. If you're
a purist, you capture the tape at 24-bit/48KHz so that you can feed it
without quality loss to the target machine. If you're more limited by
space, or want to do some "free cleanup" at the same time, you digitize
at 16-bit 32KHz and that also works.
I know of at least one person who has repaired bad tapes by grabbing the
file at 24/48 and then quantizing to an extreme level (like, 8-bit
22KHz) and also increases the volume a bit, both of which more clearly
"presses" the waveform closer to the digital signal that created it. He
writes that to a tape copy, and where the original won't load, the copy
loads just fine.
