Andy, I've resurrected a shop-worn M102 myself, added the REX module, and it looked promising! Now, I'm sending out "SOS" that the REX has added a new feature...tiled cursor that erases menu options temporarily, and up/down keys stopped.
Does that sound like a glitch, or static whoopy?

Well a couple weeks ago I was cruising eBay and ran across a busted T102 and snatched it up cheap. Completed the following to fix it up: - Restored normal functionality by re-soldering the DC jack. - Burned y2k ROM, thanks to GregS for pointing out the file location. I was planning to burn on a stash of old 27c256s, but appears I've used all of those, rather than eBaying surplus I simply ordered an AT27C256R-70PU-ND from Digikey for $1.38. This also saved me 2mA. - Swapped the leaking NiCad for a 4F Supercap, Digikey part 4704PHBK-ND. - Swapped the original 32.768k crystal for a Digikey part 300-8763-ND, which is 4PPM part, though I didn't test the original this new part should help keep better time. - Followed the 8-Bit Guy's YouTube's guide to "Retro Bright" the yellowed plastic, which turned out great aside from slightly damaging the Tandy T102 black plastic emblem by getting it too warm. :crying: Anybody have one of these laying around? I was utilizing a halogen lamp to warm the solution, got it too close... Though I don't have any specific plans for the T102 (right now it's calculating prime numbers), I've already acquired a T200, which will receive similar treatment! I'm really glad to see communities like this still active, brings back such great memories! I might even start a retro Z80/68000/etc or similar build, fun times ahead. Many thanks to all and have a great day. Andy
