Glad you asked; I actually tried making a new post in the projects thread, but apparently it ate my post or something, because I don't think it's showing.
Anyway, so far I've got the keycaps clean (rubbing alcohol scrubdown followed by an Oxi-Clean bath), but I need to know the thing works first, so I'm looking to build a Soarer converter via Teensy. I've got mostly everything I need, but since I'm an absolute n00b at soldering, I still don't know anything about what to use for wires from the DIN-5 connector to the Teensy, etc. So my first priority is getting that arranged and working.
Once I can actually determine that it works, I'm looking at going into the metal sheets/foam/etc. and taking everything apart to see what needs fixing. For starters, I know that I need to sand the rust off the top metal sheet and I'll probably give it a painting once that's done. Haven't really thought father ahead--baby steps, and all that.
But yeah, I'm stoked. First buckling spring and I'm hoping to make it a project I can be proud of. One thing at a time, I guess.
