Hi
Anyone knows availability of expansion extender for zx81? And also prototype expander pcb I can prototype with?
There used to be on sellmyretro but no longer available.
Something like the green pcb in attachment that allows connecting additional standard expansion modules in addition to the prototype i am doing
Thx

Re: Zx81 expansion pcb
That's my old picture when I used wire wrapping.
You could get a connector for the ZX Spectrum, and cut it to size for the ZX81.
I use the connector made for wire wrapping, but I connect it to Dupont cables, and on to breadboard.
