For the avoidance of confusion I deleted my post when I realised George had already covered the clock-phase issue although I should say that I found Matthew D'Asaro's troubleshooting guide very helpful when working on my 2001-8, something I mentioned a couple of times in the other thread. Care needed though because the two PETs are completely different in many respects. It just so happens that the video RAM/ROM circuitry is very similar.
