Some good info and references have already been
posted, but another
place to look is "Beneath Apple ProDOS" (the follow-up to "Beneath Apple
DOS"). It covers GCR, nibblizing and the state machine, and includes a
dump of the PROM. It references "Understanding The Apple II", which I do
not have, so I don't know if their content is orthogonal.
I expected the info in BAP to be identical to that in BAD, so I didn't
bother looking. Shame on me. I'll check out my copy of BAP to see if
there are any additional insights. Thanks for the tip!
Also, I remember hearing that there's some info in
the manual that came
with the Disk ][.
None. I've looked. Or at least, I've looked in the DOS Manual, which
came with the Disk ][. Was there any other? Perhaps one of those smaller
booklets that Apple used to send out with their hardware in the 1977-1978
timeframe?
