wasn't there some urban-tech legend about the
Americans getting
hold of a Cuban MIG fighter and laughing at the low-tech electronics they
found?
Purportedly - the Russians were using tubes! ..that are claimed to be EMP
proof.
EMP as in nuke-you-lar bomb (some important guy pronounces it like that!
bizzare..)
Now, perhaps tubes could be EMP tolerant, but they wouldn't be radiation
tolerant,
would they? After all, isn't that how Geiger-Muller rad counter tubes
work?
Any mil-space-design spooks out there worked with rad-hard technology?
I've read 4000 cmos is the wrong thing use for your home-made nuke
countdown unit,
but that RCA1802s fared better in early OSCAR and other satellites...

The Russians were right in keeping tubes well beyond what we did. That's
how they got to venus!
There are many areas tubes go well beyond what can be done in solid state.
