I have the ProDOS Tech Ref from the beginning, and it had about thirty
pages of notes with it.  I don't have it in front of me, but this is what I
remember...

ProDOS 1.0 worked with 48K.  Beneath Apple ProDOS by Worth and Lechner
(sp?) showed how to load ProDOSinto the lower 48K, so you could dbug
through ProDOS with Bugbyter (remember that thing?).  ProDOS 1.1 also
worked in 48K, but maybe I'm wrong about that...  The notes (nicely
typeset) that corrected the initial version of the proDOS tech ref said
something like "1.0 could work in 48K, but we scraped the idea, so go out
and get a 16K RAM card if you have a II+."  These notes had/have the 64K
memory maps, and said "disregard the 48K stuff; it won't work."

To recap: 1.0 worked in 48K, but anything 1.1 or later won't.  I say this
because Apple's ProDOS Technical Reference Manual had the 48K info in it,
but the corrections pages systematically told you to replace all references
to ProDOS in 48K with 64K only information.  I never got the ProDOS 1.4
update, so I've been using the old Apple reference and Beneath Apple ProDOS
sinse 1985... Pretty sad...
