my name is Michael and I made a dream come true ... 36 years later ....
At the age of 14 (in 1985) I wanted an Apple IIe so bad. Now 36 years I got one of eBay with ten non working ALPS log stem keys.
Nothing brocken, nothing damaged but non working.
I took out the 10 keys, rebent that little spingy thing and gave that brass plates a thorough wash with what we germans call "Tuner Spray 900" for delicate contacts.
It works, when I press the key it is a perfect zero ohms contact but when I release the switch it becomes a kind of capacitor and after exactly 19.7 seconds after being released that key starts to go in a kind of "rapidfire" that can only be stopped by pressing that key again and then .....
Can anybody tell me a link or show me pictures of a totally disassembled key that can give me a hint what kind of cleaning does not make those keys "capacitors" ?
All other hints and links to keyboard adaptors (PS/2) are also welcone.
The Appe ist a Apple IIe standard, ALPS long stem keys and a keyboard with noch electronics on it.
Thanks in advance.
