Time to do some proper Alps switch comparison..
Already have Apple keyboards w/ orange, cream complicated Alps, just got a Chicony w/ “Monterey” blue alps-mount SMKs, and a bag of Matias quietclick switches.
In the mail, from ebay, combined ~$116 shipped:
1) IBM 5140 “laptop”. Hopefully brown Alps & green half-width Alps
2) Texas Instruments keyboard from a 924. Hopefully green Alps
3) MTek K104. Either complicated white Alps or white alps-mount SMKs.
4) Leading Edge DC2014. Hopefully complicated blue Alps.
We’ll see how they turn out when they arrive. I figure anything I don’t end up liking, I can clean up and probably re-sell for at least the same I paid.
