Another new project (IBM PCJr)

Henlo again,

I bought this abomination of a keyboard for 10USD since nobody likes them and will try to turn it into something more up to date (different switches maybe?)

Any ideas perhaps? I liked the style of CA66 keyboards to be fair. :D

This is off to a much better start than I was expecting honestly.

An abomination of a keyboard, indeed. I respect your technical ability for restoration, although I wouldn't bother with this thing.

Anyway, mind if I reuse your picture of the keyboard so I can make a shitpo... a post-mortem analysis of the PCjr's keyboard's layout? :)

The waving quality of those hand-drawn traces on that PCB though... :)

This board was made using imperial measuring system, but measured it using metric as accurately as possible. Here you go guys, for future reference:

Are you going to handwire the original controller?

Plan is pretty simple. Draw a new mounting plate for switches and install them on that. I am considering something from Kailh as they are available, cheap and in general providing a good soundtrack as for modern switches. I won't be building a pcb for it as I don't want to spend too much on this thing. And later, I will reuse some controller from a different board. That is the most reasonable idea in my opinion. Do you guys have any switch or technique recommendations?
