Charles, Tandy Assembly will be Oct.31-Nov. 2 this year in Springfield, OH.
I hope you can make it!

Everything works as expected except that pin 7 on the cassette port is
ground! so the only spare is pin 8. Use that one!
I'll post something in the personal folders at club100...

The smallest number of parts I have so far found is runCPM
(https://github.com/kklis/RunCPM) on a Teensy 3.5 or 3.6. It is an
emulated version of CP/M V2.2 (uses a Z80 emulation) but it can be compiled
on the ubiquitous Arduino IDE. Of course it can also be run on quite a few
other platforms.

I don't mean to hijack the conversation but I would like to find out more
about Tandy Assembly, which I understand is an annual event held in
Springfield Ohio in September. I think I'd like to attend.
And let me add my
It's funny (long time lurker, first/second time poster), I was wanting to
build a low-chip-count CP/M machine based on some schematics, and was
completely floored that this is being made for the M100! I have a M100 and
a stack of M200s I bought from Tandy Assembly that I still need to fix, but
I'm
This CP/M solution is going to be absolutely amazing! Is someone planning
to show this at Tandy Assembly? I wasn't planning to have a table this
year, but if this is going to happen before September, I might want to
change my mind and plan to demo this sucker!

Very cool Steve. For M100 CP/M we can use this for external 80x24 video
keeping the RS-232 port free for TPDD which is used for migrating files
from the net.

Tonight I hope to fire characters at it using this mod.

Neat; will have to check it out.
Sounds like the perfect answer to redirecting the video to an external
terminal/display while leaving the RS-232 port available.
And if you're going to use 'real' RS-232 you'll probably have to invert it
anyway.

yah interesting. Almost the same approach.
I think it is wise to take the TTL signal from the output of the schmidt
trigger buffer, rather than from the CPU itself. So in M100 use case that
would be inverted TTL.
But overall, the same.

Interesting Steve,
As I was looking at that I couldn't help but think of the TTL output that the
NEC8201 has available on Pin 1 of the cassette port. Looks like you may
achieved something very similar.
For input you could always look to the BCR port. The two could be used in
conjunction to
I've been toying with using the cassette port to send serial data, for use
with an external device that only takes input data. Kinda the opposite of
the BCR port.
The point being - to save the RS-232 port for bidirectional comms.
After some experiments, I think it is quite useful. I have been
