ZX81 Mechanical Keyboard
That is a sweet keyboard.<p>It is rather better than my homemade one from 1982<p><a href="https://twitter.com/njcw/status/1368566103933337603" rel="nofollow noreferrer">https://twitter.com/njcw/status/1368566103933337603</a><p>My dad gave me a old keyboard from something and I traced the zx81 PCB to discover how it was wired, then rewired the new keyboard the same.<p>I connected it by burning a hole in the case with my soldering iron to poke the wires through!<p>It was a dream compared to the membrane keyboard.
