Isn't the reason the original equipment came with rubber pads was to minimize
wear of the PCB contacts? When I was a kid, the only computer at home was a
Commodore PET (2001-N - 32K, 40 col., AKA 3032 in Europe) One of the most
loaded programs, by me and my 3 brothers, was the machine-language version
of Space Invaders. You move with the 4 and 6 number-pad keys, and fire with
A. Between all of us, we wore the gold off those three pads. I can only
imagine that copper or alumimum foil tape would do it much faster.
My solution to the damaged PCB was to A) buy a new keyboard back (at $35 from
the local dealer), B) salvage the old harness, C) build a frame from an old
Radio-Shack 150-in-1 electronic kit, D) install 3 genuine arcade buttons (about
$8 each at the time), and E) mount them in front of the computer. I wish I
had a picture of it, but it was perfect - with the second keyboard harness, I
was able to mount the buttons in parallel with the keyboard, letting us play
Space Invaders without damaging the new keyboard.
