8-bit acorn hardware • Re: sampling interrupts during phi1 instead of phi2

It feels to me that, in general, interrupts come asynchronously so if the CPU reacts one cycle late (or early) shouldn't break anything. Exceptions being perhaps cycle-counted demo or game code, of course. So the Vsync, and the VIAs, would need to be kept as-is for cycle timing.

Is it easy to try it out as an idea?
