a friend did that to an old Unisys 5000/80 I bought. He had some sortof
log running that ate up the monster harddrive that thing had, and there
was suddenly no room for the tmp logging to occur and the entire machine
went south. Sure, I could have called in the Sperry-Unisys guys but one
hour of their time was more than the monster was worth at surplus.
Another friend hauled it off to make a gun rack out of the cabinet, as
it had a locking door and he had a warped sense of humor. :) Ric
