Ah, so the 8080, Z80 and 6809 are all 16 bit processors, then? They all
have machine instructiosn that can change all the bits in a 16-bit register.
Then I'll clarify it to be the size of the accumulator.
A PDP11 or a P850 doesn't have an 'accumulator' All registers are
essentially equivalent. Are those 0-bit machines?
The 6809 documntation refers to the D registers as a 16 bit accumulator IIRC
Is
someone seriously challenging that the IBM PC 5150 wasn't a 16-bit
computer?
Well, I only see an 8 bit databus on the schematics...
You're a hardware guy :)
Correct. But I don't see what differece that makes.
