Re: Zx81
No-unfortunately not. If you could find how yours is wired that would be great. I did try this mod-picture attached-I think my soldering is improving! I have tried this on the LCD and it worked really well-100R to gnd and 330R to video out. However, after a while the same issues occurred-cooling the ULA again did the trick.
However, I am in the process of removing it now.
