> Shortly after I arrived, the comp center announced a brand-new feature -- permanent disc storage!  (actually, I think it was a drum...) Irrelevant to the story (or Unix), but it was indeed a disc drive--much more storage per unit volume than drums, which date to the 1940s, if not before. Exact opposite of current technology: super heavy and rigid combs banged in and out of the disk stack. The washing-machine sized machine could be driven to walk across the floor. It would not be nice to be caught in its path. (Fortunately ordinary work loads did not have such an effect.) Vic Vyssotsky calculated that with only 10 times its 10MB capacity, we could have kept the entire printed output since the advent of computers at the Labs on line. Doug
