A project that went in with the intention of a few 'quick fixes' and ended up being several days of 'clean 38 years of grime out of it' and while I was in there, a new OLED screen, new ROM and new battery. There's no real demos here - I'll save that for another time and there's plenty online already; this just covers the trials of the repair and restoration process.
Couldn't have done this without a few incredible resources:
