Re: [M100] REXCPM & M100 CP/M

Hi
80c85 for sure
64 kB RAM for CP/M  ( dont need any more than this)
~2 or 4 MB of disk space (depending on which model you buy)

How much memory will be available to CP/M?

Is this using the native 80C85?

Yes, either a real VT-100 or perhaps more common today an serial-VGA

I too purchased one of these to use as a terminal for a single-board CP/M

Two notes: I bought my kit with the Microchip PIC pre-programmed.  The kit
came from "Silicon Chip" magazine, which is an Australian publication.
There was about a month in turnaround time as a result.

I also have a copy of the magazine with the original article if anyone is

Thanks Philip -- looking forward to seeing y'all's work!

So is a "serial-VGA conversion board" basically a hardware-based terminal
emulator with VGA output similar to the project board you pointed out?

What is the existing REXCPM board?  I am not familiar with it.

That will work with M100 CP/M. Same CP/M command (Stat) will redirect 
'screen' output to the printer port if you like.
In fact you can redirect keyboard input from the serial as well, so you

Yeah this does look interesting.  Somewhat offtopic, I just switched my
work laptop from a MacBook to a Dell running Windows (for now) which
only has USB C ports.  I could use a dongle to convert my old USB A to
serial cable but ordered a new USB-C to DB9 converter to keep things
simple.  I also had to find a new Windows serial terminal app  since I
was just using he macOS terminal before.  Then I had to test the new
hardware/software combo to ensure I can interface with all the various
networking equipment I'm responsible for in the event of an
emergency.  It'd be nice to have a simple hardware solution like this
just hanging out in the event that it is needed independent of what my
work PC happens to support at any point in time.

It's about time I chimed in here with my side of deal - which is 
producing a CP/M operating system for M100. This works with Steve's 
REXCPM board and is a RAM-based system instead of floppy disks, so no 
DVI necessary, just a REXCPM board. We have CP/M fully up & running on 
real M100s and have been enjoying testing by playing Zork! The software 
side is almost done, I'm currently  doing documentation. Steve & I have 
chatted and we're aiming for hardware & software to be available for 
everyone within 2-months.


What CP/M brings to the M100 world, apart from languages (C, Pascal, 
Forth, compiled Basics, etc) and masses of application software is "easy 
80 x 24 display". It is trivial in CP/M to direct output to the M100 
RS-232 connector, and connect a terminal (or terminal emulator) to get 
80 x 24. (Note: this *only* applies to CP/M mode, it wont allow your 
native M100 software to display 80 x 24!) So the idea is if you're going 
to do some M100 CP/M work at a desk, then plug in a VGA LCD screen that 
has a serial-VGA conversion board attached and enjoy 80 x 24. All low 
cost/energy/resource & small footprint stuff these days. A M100 with 80 
x 24 display & megabytes of fast disk is a joy to use. Then, when you 
want to go mobile, you can still use M100 CP/M, just with the M100 40 x 
8 display.


Will keep you all updated closer to the time.
