Hi, all.

Anybody know how to repair a non-ADB keyboard? The "R" key on my keyboard unfortunately does not work. I'm trying to use drakar's NeXT-to-USB adapter, and it works great except for this silly "R" key issue. Smile

Thanks.

You will probably need to replace the key switch if it's just one key. There are a couple contact points to desolder and then you pull it out.

Here you can find more pic of the internal key switch:

The Alps key switches are very common, if I'm not mistaken you can use a Mac keyboard for spares (read at my link to see which keyboards are compatible).

You should also be able to order new compatible ones from Matias http://matias.ca/switches/quiet/

I ordered some two years ago with the intention to build my own mechanical keyboard design (but never found enough time to design it) - so if anyone needs a single keyswitch, let me know (I'm located in Germany, so sending the switches overseas probably won't make too much sense).

If it's not something mechanically broken with your keyswitch, I guess chances are good that - as long as you are able to de solder it - you can open and clean it with some dedicate product and restore its functionality by gently tweaking the leaf spring.
I did it today on some Alps switches from an old Apple IIe, from dead key to fully functional in a couple of hours.

Thanks, guys. I'll try to take a look at it sometime in the next couple weeks.
