Decided I needed to do something about the rust on the metal frame. It appeared to have spread while I was waiting for replacement key switches.

All keys working fine now.
Wow looks great, seems they all get like this, the paint all crappy. How much work as it to desolder all the key switches?

These things must be dust magnets, without a doubt this is the most disgusting keyboard I have ever cleaned, and I clean my daily one once a year and that gets pretty gross.

It is somewhat tedious but it actually went faster than expected.

Yours looks pretty good! Not seeing any rust.

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?

Maybe just super glue and switch it with another rarely used key like HELP ?

That being said, if new switches are available it sounds like a good idea to grab some before supplies run out.

My A1000 keyboard and spacebar are yellower than cheese :( but the normal keys have kept their original colour. They must have used a different plastics.

Hopefully one day someone will do a kickstarter for new A1000 keyboards!

These feel kinda pricey to me, but since you need 3 you can get that many @$12.60/ea here.

I remember being shown a site - I think maybe in Germany - that sold "brand new" switches that would work, but the shipping would be pretty terrifying these days I'm sure.

I tried repairing switches myself and it did not go well. Not worth the effort to me. If you can get them, I say replace the switches.

I personally have enough replacement switches to redo my whole keyboard at this point. I just need to set aside some time.

Just purchased a bunch of mechs. Playing the waiting game for now ;)
