There are radiation hardened component for most or all chips used in the PDP-11.
The only exception might be the LSI-11 chips like J11, but the Russians might
still make some.

A radiation hardened PDP-11/34, with some interfacing extensions.
If I remember right, it was used in some fighter aircraft around 1980.[ Reply to This | Parent | # ]

What possible reason is there for the controllers to be
in a radiation environment? Particularly if they
are clunky systems like a PDP-11, a pretty big target
for a high-energy proton. The trick is to use cables and
actuator rods and stuff, and put the compute behind a
big bunch of shielding.
No matter how rad-hard you make it, it only drives down
the frequency of mishaps. Anything more than zero is too
much.
