Heat was an interesting problem...  in SAGE (NORAD), loss of A/C would result in
room temp hitting 150F in about 2 minutes!!  All that power to give the military
a whopping "80 calculations per second"...  :^)

BTW, I'm assuming it's OK to talk about this stuff 35+ years later...  aren't
the sealed records available for public viewing after 30 years...??
