Well when i discovered the M4 i read pages 1 to 93 (while i waited for my M4 order!) i think  took me about a week!!   
Its actually an interesting read seeing how it developed and was released and supported!! 

Kudos to Duke and everyone else who contributed!

Is there one you recommend to people? Don't worry if there isn't, I can always look around if I find a need to measure mains voltage.

I refer more to made the same that with soft reset made a shortcut in the expansion connector.


But if you prefer try the crtc perfect.

I can try shorting Pin 40 of the expansion port to gnd. Is is the long connector at the back?

But better hardware reset: http://www.cpcwiki.eu/index.php/Reset_Button

The CPC664 pcb is different but it may not be a good idea to add a circuit and more uncertainty. If the clock signal appear to be ok and the gate array is fine then the CRTC may be the problem. It may have worked a couple of time when I had a correct boot then failed permanently. Or could be also one of the TTL logic on the pcb.

But the clock is diferent when it power up gerald thats normal in a clock?.(crtc apart)..



If you force a reset signal when the clock is estable?.

Well, the clock should start "instantly".
If the issue is only a clock startup issue, yes, a reset could do something.

you mean a soft reset by shorting pins 26 and 29 of the Z80? tried already but no luck.
