Hi John,
This would be a challenge considering cheap SD card readers are USB and
there is nothing to drive USB from the Model T. So to use such a
device, a custom board with controller, software, etc. woud need to be
developed. This is exactly what NADSBox is, except instead of
controlling
Hiraghm,
Please keep me posted. I did find mu old Radio Shack CCR-82 cassette player
/ recorder and it cables to plug into the M100. But I have to look for
documentation on how to save and load files to and from cassette player /
recorder that is plugged into my TRS 80 Mode M100.
It would be nice
Hi Jan -
There are several such schemes out there, but $5 takes the palm!
Very nice, thanks...
Gentlemen,
Me thinks THIS is the cheapest thing where you can
build a TPDD-emulator upon:

a $5,- Raspberry Pi! (Even if it would be 10 or 15, it would be
dead-cheap!)
Load the OS, recompile LaddieAlpha, autorun, an
The keyboard is incredible. I can write down stuff in meetings without looking
at it. Indeed: I've started to use M102 in the office. Still occasionally, but
the usage is increasing.
For text file transfer to Windows and back, I'm using PuTTY and a serial USB
adapter.

Well, for me, the killer features of the M100 are a) great keyboard, and b)
runs forever on a set of AAs. Obviously, add ons don't affect the keyboard,
but anything that perturbed the things battery life wouldn't be worth it,
imho.

I'm still working on getting my Android devices to talk to my M100 via
the BlueM module.
They talk, but I'm working on creating a service and a broadcaster which
would allow one to use the M100 as a keyboard for the Android device.
I want to learn to implement the TPDD protocol, but it doesn't
I think doubling the speed of the processor might be too much however. I
know that is convenient - to make a /2 circuit. It is an experiment.
I found the original OKI datasheet for MSM80C85ARS indicates that it can
support a clock period of 320 nsec minimum.
There are faster processors that are r
I'd want to take a look and understand how the downstream parts would react
to the faster I/O and memory timing. The RAM and ROM systems are basically
asynchronous - they look for edges and respond accordingly. So long as
they are fast enough it should be ok.
The PIO chip - unclear there, but I b

thank you for your comments/ideas. I?ll do further investigations in that
