Thanks. After cleaning, very light rust. Lots of hair though!
This is what I started with:
Case and space bar have yellowing. Lots of sharpie marks all over the keys, maybe a pc emulator was on this unit? I got most of the markings off but on they keyboard case, it yellowed around the writing!
I checked all the switch, 4 needed de-oxit and started to work again.
3 keys when put on would stick. On closer examination of the stem:
I noticed some keys stuck before I removed them so don't think it was me as I use a key puller straight up. I guess this was either me removing keys, or old age. The tolerance is so tight, the plastic pushes out and binds is my guess.
Any thought on fixing these? I can find new switches but I have to purchase 100 of them in bulk
Anyone interested in buying switches off of me if I go this route? Super glue the stem? trim the black plastic so the stem wont bind?
Is it worth trying to save the old dog?
