HP-18C: 1LK7 (Saturn architecture)
39G/40G: Yorke (Saturn architecture)

AFAIK the HP-75 C/D uses a CMOS version of the processor used in the series 80 computers.


For more info on the Series 80 machines, you could take a look at http://www.series80.org/

Somewhere on that site it's stated that at least the HP-85 used an 8-bit CPU. Hmmm, I had in mind that the HP-86 used a 16-bit CPU, but I'm not sure about this.
