Just investigating the cause of the reset line being held down further, the clock signals are all present though there's no CAS signal. The Processor Halt is ok (high), and there's nothing out of ROM Enable but I assume that would be normal in reset.

Should Alice generate the CAS signal even when in a reset state or could it be the cause?

Does anyone have any other suggestions for further diagnosis to narrow down the culprit?

edit. I also just noted a lack of a Data & Address Strobes, guessing these are a symptom and not a cause?
