That's okay.  Neither have I.  ProDOS has NOT required 64K from day one.
Any version 1.0 would boot and run in a 48K machine.  That's not to say
that you could DO much with it.  BASIC.SYSTEM wouldn't run in 48k, and not
much else would either.  The ProDOS exerciser, Filer, Convert, etc. would
run in a 48K machine, as would the macro assembler (Apple's port of the
DOS tool kit assembler to ProDOS).  You could also WRITE assembly language
programs to run in 48K as long as they respected the bitmap of protected
memory areas (something a lot of programs STILL don't do).
