I've seen the weight listed as both 5 and 30 tons
for the Cray-1 in news
articles. I assume it's closer to 5, right? At 2 lbs each, the RAM weighs
only (!) 800 lbs or so.
5 or 6, some models (not complete "c"'s) less.
I read that Cray sold a total of 40 Cray-1's, so
even 20% doesn't leave
too many intact machines (although it makes my memory board fairly common
if 16000 were produced).
But how many Cybers are still around? How many ETAs? Even (non-super) IBM
S/360s are very rare (thousands made, maybe a dozen left).
