 |
|
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. 
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.
