Yup, Sandia National Labs made a radiation hardened Pentium 
and, as far as I remember, was working on a hardened SPARC -- 
there was also some work done (AFAIR on PPC) whereby 3 
processors would run the same instructions and vote on the output...



Thinking of perhaps Resilience?  http://www.resilience.com/

God, those things were horrid before they realized that the business
model of assuming "The app will always be OK, the issue will be the
hardware" was completely misguided.  I forget what the product was named
at the time, but I'll never forget what a piece of crap it was.

Eh, they're not the only folks to have had
voting-muti-cpu-lockstep-execution hardware platforms.  Stratus did it
for years; the Tandem Integrity S2 (to which I ported Emacs 18.55 many
moons ago) was similar.
