Modcomp Computer?

I was at the Uni California - Santa Barbara surplus today and saw two 5-foot 19" rack cabinets with vintage-style switches on top, so of course I went straight to them. Each rack was very similar, having on top the usual vintage plastic rocker switches (some brown, some white) for memory, registers, a key for run / halt / etc. The color scheme was brown and white, titled "Modular Computer Systems", with a ModComp logo. The insides were odd - instead of the usual card cages, a lever let you pull out a sliding tray with (very rough est.) 15 x 15 inch cards that were mounted on an accordian style fold-out bracket, which I couldn't figure out how to fold out. They were interconnected with various flat cables. The outside most card was wire-wrapped, I couldn't see much of the other cards but I got the card names and part#s of all of them: 1 of Loop Controller, 551-100169-001 1 of MC II Plane I, 551-100140-001 1 of MC II Plane I, 551-100140-001 4 of 16K memory, 551-100069-001 Each rack was configured this way. One rack had a Johnson Controls JC80 paper tape reader sitting in the bottom of the rack. The other had a smaller card cage underneath the card assembly listed above, with 6 or so cards made by Inmac; I think a paper taped to the door referred to them, listing: description model TTY Controller 3753-2 HS Serial Line 4821-1 IO Bus Switch 5213 Anyone know what this is? If anyone wants it, it's located in Santa Barbara, California - email me and I can give you the contact info for the surplus department there (or google "surplus ucsb"). I'll try to get out there on thursday and take some pictures if anyone is interested. Jeff
