Dear Bob;
I am puting together a history of low power systems and came
across the RCA 1802 as maybe the earliest single chip CMOS
processor (along with Intersil 6100). I am trying to figure out when
the RCA ICAN-7029 appnote was written and wonder if it is in
your Microsystems Manual or if you have other databooks.Thank
you.
Best Regards,
Brian

Have you seen the www.cosmacelf.com site? While I don't know if it
specifically has what you're looking for, there's a lot of history and info
available.
The 1802 is considered to be the first CMOS microprocessor, from everything
I've ever read.

The CDP1802 was probably the first single-chip microprocessor, but if
you're willing to consider multiple-chip processors, the distinction
would probably go to the CDP1801. It consisted of two chips, a data
path chip containing the registers and ALU, and a control chip. The
instruction set is a subset of that of the 1802.

The discussion was of CMOS microprocessors; the word CMOS should have
been in that sentence.
