Keep you posted about what? My adventures in CP/M assembly, or my adventures in VDP World?

What I need to do is setup a tool chain under CP/M. Text editor, assembler, debugger. Dave's page has some good starters. Thing is, I'm also after a Tatung Einstein and that is very similar to the MTX, albeit without the brilliant assembler built into BASIC (although it has an implementation of BBC tba sic! and that has inline assembly!).

I know they both use the dreaded VDP (is that a sexual disease?) and it's likely they have the same sound chips. So, apart form the port addresses, it should be easy to write routines for both; that is, use one machine as a dev platform and run code on both. That's what the Tattie was used for mostly, to develop Z80 code for Spectrum games.

So, here I am, clutching a copy of "CP/M The software Bus", and looking forward to when I have this dev environment sorted out...

There are some more CP/M books of somewhat dubious provenance here too :-

Newword in non document mode for a editor
M80 / L80 to assemble and link
VDEB for the debugger

Not exactly the most modern of setups and a lot of net searching for the syntax later you can write code.

If you attach 2 monitors, there's nothing to stop you writing code using the 80 column display, and generating output with the VDP on the other screen.

And, in yet another shameless plug for the website . . .

There a couple of tools available here :-

Plus an assembler by one of the MTX "club" (Bill Brendling) here :-
