Excellent, Wayne.

I'd like to compliment you on the great conversions to PDF that you do.
The text recognition really reduces the size and improves the quality,
and you have clearly done a fine job of fixing the recognition errors.

Interesting.  The authors have apparently developed their own
lexicon for the Disk ][ formats, quite different from the conventional
one (perhaps invented for "Beneath Apple DOS"?).  For example,
their "timing bytes" are usually referred to as "self-sync bytes" (or
"sync bytes", or even "sync nibbles", since they are not data bytes).

I suspect that since there was so little "official" Apple documentation
of the disk recording scheme, many people who reverse-engineered
it simply created their own nomenclature.  This no doubt flourished
in the copy-protection creating and copy-protection defeating
communities.  ;-)
