I remember hearing the joke that the (2 counter-rotating) drums were chrome-plated sewer pipe, but I would find that hard to believe. IIT, I think it was, had one installed on their 1108, which was on the second floor of a refurbished old building. I heard a story that pretty early on, the Univac field people were mystified by clusters of "pings" on the FASTRAND. It turned out that every time a good-sized truck went down S. Michigan Ave, the pinging would start. --Chuck
