[QUOTE="Vipersan, post: 1028775, member: 325666"] got another crazy idea in my head atm .. The non commodore project. I recently unearthed an AppleII Europlus ..which ..truth be told I had never seen running.. it was gifted to me broken over 20 years ago ... and has sat in my loft all this time.. So ..after digging it out and cleaning I set about restoring it. So far I've repaired the main board..and the floppy drive controller card.. ..plus one of the floppy drives.. not sure about the other ..this may be beyond salvage. none the less ..it now boots and gives a mono video output. I managed to find a dos disk to boot ..but ..disaster .. over 50% of the keyboard is non functional..and replacements are nigh on impossible to find. I donned my thinking cap ..and tried to think my way around this dilemma. I think I have a solution which may work. I'll reconstruct the keyswitch contacts ..outside the switch body ..like superman wears his underpants on the outside.. I'm having some success ..and am waiting for some conductive rubber tubing (didn't even know this existed) ..which might provide the missing piece to the jigsaw.. I'll send you a pic of the hopefully working replacement in due course..but for now..this is what I have in mind. ..The metal washer to be replaced with a conductive rubber washer ...thus utilising the burgered switches internal return spring. rgds Evan [/QUOTE]
