What are they doing with "80 Prospect Street" now?  When I was still 
working at Princeton, they had a "motor-generator" providing DC for the 
360/91.  It was about the size of a Greyhound Bus!  The computer room 
was big enough to play football in!

Time moves on and I've got more computing power and storage underneath
