Re: Zx81
Back in the 1980s a mate of mine took the PCB out of a ZX81 and housed it in a keyboard from an old computer system that was being removed from a commercial premises.
He did the pass thru mod and hid the power supply in the keyboard as well.
He had to peel the keypad to look at the tracks in order to copy them onto the back of the key-switches in his new keyboard.
It worked fine.
