I had a similar panic moment not long ago. I ran to the list asking for
help and then did a hard rest and was fine. I try to point it out to
everyone whenever I can now.

put that in the troubleshooting flowchart in the service manual, though.

Swap the leads around on the meter :) the black wire to the -ve voltage and the
red to gnd.
You could also try a cold boot, just in case. Hold ctrl-break and power on.
The NiCd battery is in good health?

after replacing my patch wire the screen is still blank (don't think it's

The Teensy + USB dev card + SD Adaptor should work OK, but it may need a full
RS232 I/F + driver. The Arduino Mega is more than enough so should be fine on
a Teensy. I pushed it to an ESP12 which was fun :)

It is a good set of tools that are very easy to navigate. I have ported it to
quite a few platforms now with excellent results. It just works :)

I used the FatFS http://elm-chan.org/fsw/ff/00index_e.html file system for the
SD card, it is much more flexible and avoids the nasty file and directory
rename issues. It will easily fit in a Mega – I think it was about 18K or less
compiled.
The Arduino SD.h has a few bugs in it that have
Nice work, I’ve been waiting for something to come along that would enable
internal SD support ala uIEC on the C64.
I’ll have to see if a teensy plus an SD adapter would be the right combo for a
compact setup, but I don’t see any conflicts right off the bat.
Cheers!

When you turn on the M100 does the screen come on all black? The way the LCD
controllers work is that they will turn 'ON" every LCD segment upon power
up. When the M100 boots it will send a 'clear' signal to the LCD
controllers. If you don't see the solid black screen it is an indication of

Hello!
As several of you already know, I've been working on a TPDD emulator that
runs on an Arduino Mega and uses an SD card for mass storage. I've gotten
the emulator to the point where I feel comfortable releasing it for testing
purposes.
Here is my GitHub page:
You may have already checked but make sure the –5V is good and that the
contrast pot is working sometimes they do not work so the screen is in low
contrast mode = not visible but still working. You should be able to see the
screen go almost entirely black as you turn the contrast pot or the

Glad to hear it's working in the 102.. What I have heard is that you have
to totally cold boot the 100 to get it to work if you have used any other
rom software or bank system with it.. Try that!

Greg,
I received my REX from you over a week ago, and was able to install the REX on
the M102 just fine, working great, but the M100 wouldn't finish the "call"
command, and I would try reseating, checking the pins, being very careful to be
grounded, so on. Treated the M102 just as carefully,
