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. > The 3B20 was another > thing. It was a work of telephone company art.

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. Perry -- Perry E. Metzger perry@piermont.com
