When I started grad school in Cincy, there was an old analog computer that took up 3-4 racks in the VAX room. I heard some mumblings of what it was good for, but never saw anyone use it. The profs who did IC design work always spoke very respectfully of the analog IC designers out in industry - they were doing so much more interesting work than those combining masses of flip-flops into ever larger circuits.... ;-)
Cheers,
Scott.
