In answer to your first question, Will - it’s actually both. There's the desktop app that lets you use your PC as a terminal (which is the screen shot you linked to), but there's also an adapter that lets you connect the M100 directly to a VGA monitor (the MVT100

How did you test the contrast pot? You'll want to turn the machine off, and use a multimeter to test the resistance between the wiper and each of the terminals (they're each connected to R10 and R77) on the pot... and of course, make sure you're taking the measurements from the ends of the resi

Re: [M100] Possible M100 prototype.

I don't think you're wrong - all of my M100s are 110CH1X. 1010 certainly seems to be an earlier revision of the board. Just curious - what's the date code on the CPU? I can't make it out with the cap in the way. Also, if you're up for dumping the ROM, it would be interesting to compare it to a

Re: [M100] rexcpm battery

Great work! To make sure I’m following - the REXCPM relies on having a ground path through the socket, so the idea is to swap out the 3-wire JST connection for a 4-wire version, which adds the ground pin... And you’re saying the only reason it works outside the unit right now without the ground
