A mechanical keyboard that’s compatible with the Sinclair ZX81, as well as the ZX81+38 modern recreation of that machine. This repository contains all the design files as well as various exported versions and images. Please carefully review any files before you use them to order hardware!
In case you were, like me, wondering about the ZX81plus38, here’s a description:
There’s also a detailed development blog: https://revspace.nl/ZX81plus38_simple_to_build_ZX-81_clone. If you’re not in for long reads, there’s alternatively a YouTube playlist.
