I suppose you could do what you're saying, but that higher speed would have to be really, really high, since getting the maximum performance from your '816 system would require being able to put that latching edge forward or back in steps no bigger than a few nanoseconds each until you find that ...

I talked to Bill Mensch (the 65816's designer) about this a couple of years ago, and he acknowledged that the circuit shown was not suitable for the higher speeds. I haven't done it yet, but I think you'll need variable delay lines to move the latching edge forward and back from the rising phase-2 ...

hi, all.

does anyone have any idea where i can find a supplier for 6502 and related ic's in the uk? i've tried cpc, rs, maplin and farnell - farnel have some parts in their catalogue, but none in stock and all lines are marked obsolete.
