All of the campus workload had moved to UMC (Columbia) from St. Louis, so they were idle for 2 or 3 years. he had them as PC's They were stacked on on top of the other, but powered and running. If one wanted the ideal small footprint setup, the best would be the 4361, 4320, and a 3370. The 4361 was I think the only system with a builtin storage director, and the 4320 could connect directly to a channel w/o any controller. The 3370 IIRC correctly was FBA, and I think the controller was FBA (someone corrected me which one it was last time this came up). But any 43xx would be fun to work with. I worked with a maintenance group in the mid 80's and we got 3 or 4 of them scrap, and they all just turned up and worked. almost all the stuff that anyone had had running worked if it was properly de-installed and move in my experience. Might have been unique, but very solid designs and good documents with that hardware. thanks Jim
