The big thing I know about is they tend to use SRAM for everything, rather than DRAM. Apparently SRAM is less susceptible to bit flips from radiation.

Right, but did you leave it that way for a few years? Hell, Voyager 1 was launched in 1977 and is still operational, according to Wikipedia. How many computers do you have that have been in continuous operation for 30 years? :) -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
