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.

Methinks you are doing that backwards. You should be booting into
Prodos, loading the Dos 3.3 file then doing a kind of emulation where
your ouput checks for disk commands when running your binary programs.

...well, that's basically what I was planning to do. Take a DOS 3.3
image, patch it, wrap it into a SYS file.

Ok I found my short code for executing disk commands.
2000: A2 08 BD 0E 20 9D 00 02 CA 10 F7 4C 03 BE
200E: C3 C1 D4 C1 CC CF C7 8D 00 00
It is so short I entered it from my iPhone. -_-
All you would need to do is monitor output for a CTRL-D character,
check the incoming command which would terminate with an $8D
character, then jump to this short routine with the se command.
At least that sounds easy in theory.
