Hey there Belsamber. On the off chance you're still lurking about the PINE64 forums, I just wanted to tip my hat to you and say you've inspired me to do something quite similar to your Model 100 / PINE64 project.
In my case, however, I chose the Tandy 102's keyboard as it feels much better to my fingers. I happened to have a dead 102 in my stash of retrocomputers. While the keyboard is definitely preferable to me, I wasn't able to use the actual Tandy 102's case as it is quite a bit thinner than the TRS-80 Model 100 and wouldn't fit the 4-cell 18650 battery pack, PINE A64-LTS v2 board, and 8.8" 1920x480 display inside the case.
However, I *also* had a TRS-80 Model 100 that had a damaged motherboard. This just meant marrying the Tandy 102 keyboard with a Model 100 case. Not too big of a deal except it lacked a few of the holes in the PCB which must be used to affix the keyboard to the top-case of the M100. That was easily fixed with a drill, and lucky there weren't any traces close by. Also, there's only 18-pins instead of 20 on the 102's keyboard connector, and it is an edge connector instead of the JST type. With an edge cable recepticle, this was easily solveable and the wiring was mostly the same, just shifted a tiny bit.
I actually was able to reuse your keyboard strobing python script, and I highly appreciate the work you did putting that together.
Anyway, just wanted to say thank you for the inspiration. I probably should write it all up and snap photos and post a blog entry at some point..
Regards,
Voidwatcher
