A comment on A working, transistor-scale replica of the MOS 6502 microprocessor.

It's a shame they didn't mimic CMOS construction instead of NMOS. A 65C02 made from discrete parts could have run at full speed, wouldn't have required dual-gate MOSFETs or other weird parts, and could have plugged right in to the original 6502 microcomputers.

As a bonus, it could have operated statically -- not clear if this one can or not, but I'd guess not, if they were truly faithful to the original 6502 schematic.

Still a cool hack, though!

AFAIK no one has reverse-engineered the 65C02 publicly, so that would have to be done first; it'd also require approximately twice the number of transistors and area, so the speed won't be much better.

The speed will certainly be better, due to the way NMOS works.

NMOS is pretty terrible.
