Hello everyone. I was playing around with my Kaypro 10 recently, and the keyboard took an unfortunate spill. When I picked it up, I noticed that the ESC key had broken off at the post. :mad: Is there a good way of repairing these switches, or any known sources of available parts? I have a Kaypro 2X which was involved in a flood that I could possibly scavenge parts from, but I'd rather not resort to that if at all possible. Thanks in advance!

I believe they are standard cherry switches and "back in the day" used to replace them.

It should be easy to find a new switch.

I would look long and hard before doing the obvious and glue it back.

The Kaypro used a switch with a + shaped plunger.

Thanks for the reply. I'm not sure who made the key switches in these keyboards, though I've seen references to a company called "SMK" in this forum post (https://deskthority.net/photos-f62/vintage-find-2-nos-maxi-switch-kaypro-replacement-keyboards-t5563.html), along with photos and more info here (https://deskthority.net/wiki/SMK_vintage_linear). Most of the Cherry switches I've seen around were of the MX type, which was introduced after the Kaypro 10 was released, so these SMK switches would seem to be it. Is there a known source for these SMK switches? Can Cherry MX-type switches be adapted to work in their place? Again, thanks!

Most of the keyboard switches were interchangeable - mainly had to make sure of post design.

Desolder the broken one and check dimensions and where the solder tabs are located.

I believe most electronic suppliers sell them and have detailed spec sheets to compare dimensions. I tend to user mouser.com.
