Hi all, read only member so far, located in Ukraine. Not long ago I became interested in vintage computers/calculators, so naturally I bought a couple of Model 100 and 102. One of the M100 had a LCD problem - missing vertical line, no cleaning/zebra strip swapping helped, so I think there's a problem with trace on the glass substrate or failed driver chip. While trying to fix it I broken a couple of metal "ears" on the metal frame that holds screen... One of the T102 came with extensive motherboard damage from leaked batteries, I tried to repair traces, but couldn't make it work. On the other one there's corrosion in LCD connector(screen PCB side).
So out of 4 machines I got 2 fully functional. Now I'm looking for one damaged screen for M100 with fresh metal frame and working T102 motherboard, preferably without corrosion.
