Another even more compact format would be to simply represent the stream

Monitor's cassette write routine.
OK, if this is the case on the Apple then fine. On the Commodore it is
most definitely not the case, most tapes had a short standard format
booter, which then used its own routines for loading the rest of the
tape, talking directly to the hardware. Are you sure this was not done
on any Apple tapes?
Not to my knowledge. Because disk drive arrived so promptly on the
Apple scene, only a relatively small number of cassette titles were
made--probably less than a few hundred.
My local Computerland sold only about 15 titles in early 1981. I'm
sure that many more were available by mail order, but the market for
them was relatively small, with even fewer surviving until now.
Does anyone have any non-Apple-standard Apple cassettes? (And what
would be the point, since it would hardly make them less copyable,
and the Apple cassette interface was about as fast as could be
reliably done, at 1500 bits/sec.)
