Yes, Georgia Tech got 3B2s and 3B20s. An instructor there referred to the 3B20s as white elephants, and explained it to me (since I didn't know): A white elephant is something obviously rare and valuable, but what exactly do you do with it? :-) Ours had a bunch of the CDC 300 Meg washing machine disk drives. A huge amount of storage for the time. We (the lab staff) wanted to port BSD Unix to them, but that never went anywhere. > The 3B2 was the first machine that I came across I think with a soft > power switch.

The 3B1 was a pleasure in comparison. Afforadable on a personal level and eminently usable. Arnold
