Re: Zx81
I tried the '81 this morning and left it running without modifications for just over two hours - unfortunately the same thing happened. The unit rebooted and then the picture was lost. I tried retuning the TV but it was clear that it was the computer. I squirted the freeze spray onto the underside of the PCB where the ULS is situated and immediately the picture returned. I guess this means a new ULA? :-(
