No ZX80?

This is a thread derived from "QL prototyping board..." There's are a couple of ways to do it. It depends if you just want to pass a. Yet back and forth or if you want to address a block of memory. It would need some hefty GPIO on the pi's side. I'll email you in a bit and we can talk more...

There's are a couple of ways to do it. It depends if you just want to pass a. Yet back and forth or if you want to address a block of memory. It would need some hefty GPIO on the pi's side. I'll email you in a bit and we can talk more about it. I'm interested in these discussions as well. Please us...

Sorry, I lost track of this Thread. Is the new interface available somehow?
Kind regards Paul

If your machine hard locks, does it still answer ping requests? Could you use rlogin or such tools to get some diagnosis? Or via a serial line? I know it's hard to do anything without screen but I don't remember having my linux machine totally locked out. I admit I know little about linux and after ...

I am also interested in these. I guess this backplane is unbuffered. Wouldn't it be better to have a buffered version? Also I think some extra holes for cardholders would be good. I use these for example. https://www.reichelt.de/Distanzhuelsen-etc-/KARTENHALTER/3/index.html?ACTION=3&LA=517&A...

How about having something compatible to a SGC?
You could also do the same as sinclair,
Disable the cpu when not used Kind regards Paul

I am also interested in the pcb (two or three) only because I have plenty of both connectors and which should also keep postage low.
Kind regards Paul

That's a really hard decision. I prefer using larger CPLD with lots of io pins even when not neccessary. It's really hard if you implemented 90% of the logic just to find out you are going to miss some macrocells or io pins. Once everything is running I still can decide to use smaller devices. Using...

Spectrum Color hardcopy has been tested?
That's better than expected!
Meanwhile I remembered that I still have an Atari ST, has Signum been tested?
Else I could do this (or different ST Programs).
