Been poring through Beneath Apple DOS and 2 different disassemblies just
trying to figure out, first of all, what code I'm going to have to
rewrite.

Again the idea is to make a minimally invasive graft into DOS 3.3 that
just translates File Manager calls to ProDOS calls, and probably gut the
RWTS.

What will be your destination file system? ProDOS or DOS 3.3?
I mean: do you want to access DOS 3.3 disks from a ProDOS volume or do
you want to access DOS 3.3 files stored on a ProDOS volume?

The characteristics of the file system are so different that I have no
clue how you could handle DOS 3.3 filenames on a ProDOS volume:
allowed characters and filename lengths are sooooo different!

Good luck with that one! That can be done (DOS.MASTER or Copy II plus
convert program)

Well, patching filenames is easier than rewriting code wholesale. xD

I was going to try to keep as much of the code as possible to make rewriting it easier, figuring I could start just by plugging in replacement "open", "read", "write", "close", "catalog", "check filetype" etc., which I have at least some of.
