Brian,
Definitely. DDT is great. I'll be working through that next. I finally
got a program working and assembled - from the 2.2 manual - read chars
until *. Now, I just gotta get hello, world working.... I was sure, it
would work... oh, wait, when it says to CALL CPM, I bet it's not talking
about where CP/M is DE1EH... I bet it's that 0005H entry point... off to
explore.

If you just want to play, don't discount ddt in CP/M. Cheap and dirty
way to play with everything.

regarding file transfer, use

These programs access a "TPDD". Filenames are 8.3 format,
cheers

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: http://bitchin100.com/wiki/index.php?title=M100_CP/M
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.
