after a bath, a Pioneer clicks no more

I completely disassembled the keyboard and replaced the plastic rivets with micro screws. I cleaned all the various layers of film that make up the keyboard and restored the damaged tracks with a conductive marker. It worked well. I guess the 48 has the same construction philosophy. You can find details here.

What a thorough work, thanks for documenting it! I don't plan anything of such complexity, at least not at the moment and this calculator. If anything bad happens to my main Pioneer, your restoration record will be invaluable! Once again thanks for it, I love when people do and write such things, IMHO it's the best part of this forum.

On a related note, I "plan" to repair of a 28s. I suspect the only thing bad there is the pressing foam, making not enough pressure. With all those hard-to-remove labels and rivets it's a job for someone as skillful and resourceful as you are, not for my butter fingers. Currently I'm at phase 1, plucking up courage; this phase has already been taking several months :-)
