Re: What we need
And only putting three registers on the 6502 was just dumbfuckery of the highest order.
It's my understanding that the 6502's original target market was controlling microwave ovens, for which its capabilities (notably the 256-byte machine stack) are just fine.
But yeah, the Z-80 was a far more sophisticated processor than the 6502. If you compare it to a 6809, well, them's fightin' words...
