Re: What processor? Message #2 Posted by Raymond Del Tondo (Germany) on 4 Feb 2003, 7:26 p.m., in response to message #1 by Matthias 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. Raymond
