DIY Mechanical Keyboard

Post by code-surfer-dev »

I recently built a prototype mechanical keyboard using Gateron Blue key switches which I am using on a ZX81 & TS-1000. Anyone interested can check out my blog:

There are two parts. I would love to get your thoughts and feedback. Thanks!

I'm deep into state machines, truth tables, Karnaugh maps and CPLDs. :-)

I just programmed a GAL as a five bit tristate buffer to interface the DIY mechanical keyboard to the ZX81 via the expansion port, no where near as complicated :)

I am autodidact in this so I am slowly working myself through a text book and YouTube videos.

I didn’t think GALs were complicated enough to support tristate. Great to learn something new.
