Actually, M100 ROM routines will be available to CP/M apps. I propose a
memory address in BIOS where you poke a desired ROM address, then call a

Ok, good to know. I suppose 80 or 60x10 in CP/M would be a nice project.
The Amstrad NC100 CP/M certainly implements that (120x10 rather than 80x8).

Zero chance unless someone takes the time to port them. And it
REXCPM is planned to support the 40x8 LCD, and an external TTL serial
display (like a terminal emulator). No plan I know of to integrate the
LCD based high density characters.

Good to know! DX-Forth then is much better given its access to the CP/M
filesystem.
Any chance the 80x10 or 60x10 display enhancements will work with REXCPM?

I believe so as it's 8080-compatiable. What's more its built-in editor
(SED) is fully configurable with documentation & source, so we should be
fine with that too.

Oooh! 40x66 would be most helpful, especially for the terminal.
What CP/M terminal applications work? How about Forth?

Well, that would be possible as there are 60-column and 80-column
utilities for the M100, but they are difficult to read. I think the
uptake on this would be small as the alternative of external 80 x 24
(36) VGA wins hands down.
We do have loads of RAM, so a virtual 40 x 66 (or say 256) lines
Good to know! How about DX-Forth?

Yes, standard 8080 CP/M software works, which is most of it. However
Z80-specific software wont, VDE & Turbo Pascal come to mind. Instead of
VDE (a full-screen editor), I'm using Word Master as a full -screen

What we have available to us is a recent change I've proposed to re-use the
cassette port as a high speed serial link for external display.
Requires only a single wire be added to bypass the Tx filter on the
cassette port, and bridge the fast TTL signal onto pin 8 which is unused.
This does what
Also, is there any chance of resizing the font or making a virtual 80x24
window? I think I saw a NEC PC-8300 with an Option ROM giving 60x8 or 60x10

Oh wow! This already sounds so much better than klutzy (well, slow,
individual) xmodem transfers in ZCN on the NC100.
As far as full screen CP/M, this would be over the serial port? Is there a
parallel port alternative? It would be nice to keep the serial port for
dumb terminal usage.

Yes there will be a process to push out and reload the ram disk to an
external device, like LaddieAlpha or mComm.
There are also utilities with CP/M to allow loading individual files
from/to TPDD to/from the CP/M disk.

Hi Steve,
Thanks for sharing the info! Since the REXCPM has SRAM, will I be able to
back everything up with VirtualT or mComm?
Thanks again,

REXCPM itself plugs into the option rom socket.
In M100 and T102, you need an additional board
1) in M100, the adapter plugs into the system bus and connects via a 3 wire
cable to REXCPM. No soldering, plug and play.
2) in T102, the adapter plugs into the adjacent 8kRAM socket, and connects

For REXCPM, how much hardware modification is required? Does it need any
wires soldered to the motherboard?
I have a Model102, if there is a difference between 100 and 102 in this
regard.

I can comment on the hardware side of things. Standard REX does not
support CP/M as it is FLASH only.
REXCPM is different hardware. It uses Static RAM (either 2MB or 4MB) as
opposed to FLASH. In order to run CPM you need 64k of addressable RAM.
REXCPM does a few things to make that happen
1)
Hi all,
Just curious about the state of this new REXCPM! It sounds incredible! Does
it offer CP/M plus 4MB Flash RAM for storage? Does it change the number of
lines/columns on the display by using a smaller font (like NC100 ZCN)?
Could the regular REX also be configured to run CP/M?
