There is an optional pretty easy modification we can do when building the
existing design, to make a more reasonable port_en touch point.
Cut the trace from C1 to R3.
Install R3 over the cut trace.
Solder bridge the two pads of the original R3 location.
Now the unused pad of R3 is a nice big ta

I ordered six boards and corresponding parts, plus two of the Macronix flash

I have to say, this worried me when I first read it, but not as much anymore as

I have gotten REXCPM working on my bench. I built the first unit with just
1MB of SRAM, while it is capable of 2MB.
I am able to bank switch, read and write. That's pretty much it. I have
some additional verification to do still, and making sure that the SRAM is
protected during power cycl
Perhaps I should remind everyone at this point that I wrote a program

other time zone change.

Stephen, yes - that works perfectly. The situation I was describing above
is after a CTRL-BREAK-RESET total wipe of the M100 after I have wedged it
completely - then reload RAM from REX.

At some point in REX I included a feature to maintain clock setting through

Peter,
The current clock in the M100 does just fine usually. Unless it sits for a
long time. My request for another one is just me being lazy. (sort of).
I use my m100 in strange ways and often I have issues where it crashes or
locks up and requires a total system reset.
Most of my activities wit
Yup. If you have a clock, you know what time it is.
If you have more than one clock, you don't... :)

Hey John,
To move RAM images around I"m using REX, creating a backup of the RAM image
and saving it to "disk" or in this case Mcomm or my NADS. I like Mcomm
because the directory it saves everything in on the phone is automatically
backed up (by another application) to dropbox right now. Then I lo

Wow. This sounds very cool! I've never actually run CP/M, and I'm not sure
that running it on Model-T is super exciting (probably just because I

flexible flash/ram storage. Specifically, 4MB of flash and 2MB of SRAM.
