A piece of trivia the Voyager space craft used the RCA 1802. It was quite r=
adiation resistant because of the rather large track sizes on the silicon. =
Radiation would ionize a local part of the processor generally without enou=
gh charge to change the logic
state. The 1802 was laid out on mylar like an old time PC board and photo r=
educed then etched on silicon. Times have changed.
