From what I understand, the computers NASA uses in space are often ancient, the shuttles were 486's I believe. They test things to death, at least for computers. Also, I suspect older chips (bigger transisters, etc.) would be more resistant to radiation effects.
The five computers in each of the space shuttles each used the same processors as IBM mainframes. Technology from the early/mid 1960s. If only they'd had 80486 CPUs...
