They can be fixed w/thorough cleaning[soaking] in diluted windex or 409[diluted] Rinse in degreaser [test it first] and sun-dry. If you want to go further,construct a ultrasonic bath with audio sig gen and tweeter or quartz transducer if you can find one. Now I've just done this and KB is OK,I need a source of conductive paint [that remotes use-the thin-film depo stuff] to repair the ribbon conductor end where coke has eaten it off. Haven't used this stuff for years.TIA Pete Peter Neal Neal Electronics 1905 E.
