I may just do it. I have a working 102 and one that works sans some bad lines on display due to a bad display driver chip. It is fixable if I can find a spare chip for sale as a drop-in replacement. I don't want to sacrifice it if it is largely fixable. I've been looking for a dead one on ebay for less than $20 but people want crazy money for even a dead one. If I can get my hands on a dead 100, 102 then I'll get started reverse engineering the board in CAD and see how it goes. I may ask the bitchin crew if someone has a dead 100 they're willing to donate. Daniel
