The topic of single phase vs. an 11/780 reminds me of a little prank back in college
around 1990ish. I had a few part-time jobs at various times in one of the computer support
organizations back then. First as a backup operator doing tape backups on a graveyard
shift, then later as a consultant at the support desk doing noob-support, then later in
another portion of the department doing tool builds and light UNIX programming. They paid
me and everything, so it's good that I never mentioned that I probably would have done
the job just for that key to the machine room and the root passwords they gave me... The
best part was being able to do homework after hours on the department's Sun
workstations and VAXen rather than fighting over older workstations in the EE and CS
department terminal rooms. Pretty much unlimited access to VAXen, Suns, Decstations, and
even a NeXT cube. No silly CPU, disk or printing quotas, and 24/7 access to the main
machine room. Good times, good times...
Anyway, once a friend of mine and I decided to play a prank on our boss while he was away
on vacation. There was a decommissioned 11/780 or 11/785 in the machine room. We noticed
that the blowers were all 120V single-phase, so we pushed the main cabinet down the hall
late one evening and crammed it into the boss's office. That was a tiny office, and it
barely fit with enough room to squeeze by. Then we plugged in a few fans so it sounded
like it was turned on, stuck a small hard-copy terminal on his desk, and manually typed up
stuff to make it look like we were trying to boot the beast. I wish I could have seen his
face when he got back from vacation...
Later on, in another part of that department, another vacationing boss got a TU-77 rolled
into his small office and turned on. Not my doing, but that was another classic.
