My dad recently gave me the original Apple ii plus that he bought and I learned to program on. It wouldn't boot and after some troubleshooting, I found the highest range of RAM had a bad chip. I replaced the entire bank of 8 chips (as I saw was recommended on one of these forums) and it worked! I bought some new 5.25" floppies and was able to create some new disks using the Apple Disk Server (awesome resource!) The power suplly is working but I proactively ordered a capacitor replacement kit.
So everything is going great - my 17 year old even started writing programs on it because they love the challenge :)
And then the letter A stopped working :( I popped the key cap off and blew out the dust and I tried the hit-it-1000-times-trick but it's still not working.
I am an eletrcial engineer by training and learned to solder when I was 12. So I'm up for the task - I simply cannot find replacement switches.
Anyone no where I can source Apple ii plus key switches short of buying a spare apple ii plus? Or is there some other technique for repairing a switch I haven't found in my google searches yet? (I do have contact cleaner but I'm unclear where exactly to use it - do I need to remove the switch and take it apart?)
