We had huge numbers of 3B2s at Columbia that were gifted to us by
AT&T. They didn't know what to do with the things, so the undergrads
were subjected to using them for their labs for a few classes like
computer graphics. The blits attached to them were neat, though. If
only the same could have been said for the overall system.

We had one of those donated, too. It was put into an extra machine
room and not used for very much, I think because the version of the
OS it came with didn't really do networking at a point where
everything else at the Columbia CS department did.
At one point we considered reusing its disk pack drives for some of
the Vaxes but unfortunately the cabling was incompatible.
