Here's a semi-interesting page of quasi-historical importance
about uP's of the past. It probably doesn't jive with the
classiccmp list view of reality, but discusses 40xx's,
and {non-authoritatively} answers one members question
about the uP in the Voyager probe:
"Apart from the COSMAC microcomputer kit, the 1802 saw action
in some video games from RCA and Radio Shack, and the chip
is the heart of the Voyager, Viking and Galileo "

We especially like the 2nd IEEE Computer article in Apendix E.
