Come on guys cool it. Who really cares if a Z80 is faster than a 6502 ?
I sure as hell don't.
For those who are interested check out the following:
US Patent 4004281 Microprocessor Chip Register Bus Structure (6800)
US Patent 4332008 Microprocessor Aparatus and Method (Z80)
US Patent 3991307 ...on the fly correction to provide decimal results (6502)
By the way, the 6800 Patent has complete circuit diagram.
The Z80 also contained DRAM refresh circuitry that the 6502 didn't.
