Howdy,

Interesting comments about the "hardening" of the microprocessors
for the Mars rover.  Mark Sims points out that, for all that
extra care, the actual communication links for the rover, the
very electronic umbilical on which the ultimate survival of the
rover depended, were off the shelf commercial Motorola radio modems:

which were "modified" to JPLs specifications, which no doubt utilize
modern microprocessors, (anybody know if this is true?) and which
he "sincerely doubts were similarly hardened."  Interesting, no?
