The keyboard damage and subsequent repair is
interesting since I don't see
how it could've happened without breaking either the case or the keys
themselves; it's like something's punched right through the circuit board
and physically broken it, enough to push a section of it out by 2-3mm, and I
don't believe that someone would go to the trouble of replacing the top
section of the keyboard AND repair the circuit board.
The hole's been shored up with a hot glue gun and the tracks replaced with
nice blue wires soldered in....
Had this been a TRS-80 M3 or M4, I could understand it. There's a plastic
post in the case that seems to be designed to punch a nice hole in the
keyboard PCB (a horrible SRBP thing) if you drop something heavy on the
keyboard. Please don't ask how I discovered this ;-)
