Which one, the original or the Tindie version? I thought the Tindie version (
U$52.00`+ S ) is out of stock?

doh that's the one I ordered... will have to do a run of the other boards
then :) and put it in my store when you get it all figured out I'll get that in
motion

yes, I am basing this off the original design not the one on Tindie.
The tindie design uses new firmware, and a faster clock. Not doing that
work.

Hi Steve,
Did it ultimately end up essentially identical to the original except for
the DE-9? (The original board has a 4-pin low voltage TTL header).
I ask because I have a few extra of the original board just in case
someone wants to do it the hard way, assuming any firmware upgrades will be
compatible.

regarding the kit.
The kits available don't have a convenient RS-232 connector.
I redesigned the PCB to support a DB-9 connector. If you can wait,
I'll have that ready soon.
If not, then I think you can go for Tindie ($$$) or the source that
Geoff cites on his site.

Where did you find it, Greg? I haven’t been able to find a kit.

next update:
I have a beta version of the VT100 driver working now. It's
pretty neat to have a modern display hanging off of the M100!
The current version works with the "stock VT100 adapter" with a
few issues. What needs to happen next is a software load for the VT100 adapter
that provides a few extra commands that the M100 needs.
The VT100 driver works just like Microsoft Disk Basic, in that
it integrates with the M100 OS to enable direct access to an external CRT.

update:
Towards the goal of a next-generation video solution for
M100, I have some progress to share.
Recall this thread where I suggest that the "Geoff VT100
adapter" as the hardware to focus on.
First, I have a "beta" VT100 driver solution, which is
closely based on Microsoft Disk-Basic (minus the disk stuff).
While still buggy, I can now drive the VT100 board, and
attached VGA monitor from BASIC.
Secondly, in order to really support M100, the software
component in the VT100 emulator board needs to be extended. I'm working on
that. This does imply that the "Geoff VT100" board, as it was originally
designed, won't work perfectly for M100. But, I'll post the updated software
image so anyone with this board already can update their board.
I'll keep posting updates as this progresses.

As some of you may recall, it is fairly straightforward to
access an 80x24 screen in CP/M through the use of the M100 serial port, and an
external VT100 emulator.
This device:
http://geoffg.net/terminal.html
is a great example of how to connect a modern VGA flat
screen display to the M100. However, this exact design isn't really
convenient, as the serial data has to be connected with a custom cable. (see
the little white 4 pin header).
I've decided to make a variant of this design that has a
DB-9 connector on it, for serial data, so that it can be easily connected to
the M100.
I'll be making kits available for this design, and the
price will be 30$ US. Hopefully by making this affordable and easier to
connect, this can become the defacto solution to 80x24 display!
This solution will work with CP/M right away, but the next
task will be - how to use this solution with Model T natively. This will take
some software work. A port of the "DVI software" to leverage serial
communication to the VT100 adapter is one way to do this.
This solution is also compatible with the "BCR serial port"
modification which allows for serial data transmission at up to 120kbits/sec.
A nice solution to exernal video that frees up the real RS-232 port of the
laptop for comms.
I'll be updating the REX wiki with some information on
this. Kits aren't ready just yet. I'm waiting for my boards to arrive.
cheers
Steve
