Like many others, the cable for my 102 keyboard has seen better days. When I got the unit, a swath of keys didn't work, so I re-seated the connector, also while trying to reverse the snow-plowing that had occurred previously. I got it to work and it worked for a few months, but recently it failed again. I tried re-seating it but then the plastic backing fell off and the wires seemed even worse.
After MUCH searching I found a (mostly) drop-in replacement: Mouser has an 18-pin 1.25mm pitch FFC cable, "D-style" (a.k.a. "opposite") orientation: https://www.mouser.com/ProductDetail/Molex/15168-0250?qs=N2VrfF4LzQfZl7gQv3Ba6g%3D%3D&countryCode=US¤cyCode=USD I installed the cable and it worked okay, but I found it was loose on both sides, so I used a playing card as a shim and now all the keys work again. Yay! Unfortunately I could only get it in the 229 mm length (9 inches) instead of the stock 150 mm (6 inches) that comes on the M102. That's OK, since it's the "ultra flexible" variety I was able to just sort of stuff it under the keyboard. Hope this helps someone save their 102 too! -David
