I broke down and started reading the manuals (REXCPM, CP/M 2.2, etc).
It's starting to come together (again?)... I've inlined the answers I
figured out for posterity or the next clueless newb who comes along.

2. CP/M works from RexCPM, which is great, cuz CP/M recognizes more
memory:
64K CP/M 2.2 M100 CP/M + REXCPM 2MB 1.0
Yes, it does recognize more memory and it serves up an A: drive that's a
big chunk of that 2MBs. Solid. Talked about here:

My questions are as follows:
4. In CP/M, how do I get back to MENU?
Duh, F8 :).
5. When I start CP/M, is it just running CP/M against the M100's
memory or am I in some special whizbang virtual environment where I
have additional disks available somehow?
It's a whizbang environment for sure - 64K ram and a nearly 2MB A: drive.
As for my broken ASM, another duh, thanks John for the tip - I need to
write a CP/M friendly program that call it's routines and not the ROM calls.
CP/M seems the way to go, though. It kinda reminds me of RT11, but with
ASM instead of MACRO11. ed... well, after you figure out that you need
to retrieve the file contents into the buffer, it kinda makes sense -
nice video - I love ED:

Still need to figure out how to get files into and out of cp/m though...
Off to read some more.
