Commodore 128 Keyboard Repair

The RETURN key on my Commodore 128 stopped working recently so I decided to investigate why and try to fix it.

SPOILERS: The conductive part of the plunger for the RETURN key had worn off (probably because I cleaned it too thoroughly previously) and I managed to replace it with a spare part salvaged from an Amiga 500 keyboard.
