- Yea, but if you don't decode it, it's likely to get pretty big.
- Most PCM style recordings do get pretty big. It would be interesting
- to investigate the hardware and see just what you could get away
- with in terms of sampling rates, etc. Also, being able to decode
- the tapes might make it possible to restore programs where sections
- of the tape have become illegible. Most of the old machines aborted
- when they hit an error. If you could write a PC program to load
- the whole tape, you could probably correct most one character
- errors, or maybe use two corrupted copies to fill in the gaps
- that each has. You could also clean up a marginal recording,
- maybe the tape has stretched some and the frequency shifts a little.
- You could make the program smart enough to detect and correct these
- problems and produce a "perfect" program tape.
