Reordered your list by transistor count and added caveats...


>From Microprocessor Report, in chronological order:

>8008: 3.5K transistors 14 mm^2


>1802: 5K transistors 27 mm^2
   if 1802 were done in Nmos it would have been far
   lower transistor count. As it is CMOS there are
   many cases in the logic where two complmentary
   transistors exist where NMOS would have used
   one. It is also the ONLY one on the list that was
   fully static logic. Its registers used a lot of
   transistors as the raw flipflop.

>6502: 4K transistors 21 mm^2

     fewer transistors and also a clever design
     made for an easy mask that had good yeild
     for the die size.

>6800: 4.1K transistors 16 mm^2
>8080: 4.8K transistors 20 mm^2
>8085: 6.5K transistors 20 mm^2
>Z80: 8.5K transistors 18 mm^2

>6809: 9K transistors 21 mm^2
>Z8001 17.5K transistors 39 mm^2
>8086: 29K transistors 33 mm^2
>8088: 29K transistors 33 mm^2
>68000 68K transistors 44 mm^2

Thanks, it's not as if the data was a top secret.
