what do I do with a Multibus?

Just picked up an interesting unit at a hamfest, there was a box with a large power supply, a long tube with BNC connectors at each end(some sort of attenuator I suppose), and a large jumble of cards inside a backplane. Well, when I just got home now I dug through it, and found a few interesting things inside. The first card is from Intel, with an 8086 CPU and some other stuff. Attached to the CPU board are two daughterboards, one with a connector and an 8272 chip, and another with an 8203 and a bunch of EPROMs, as well as a lithium battery. There are a 50pin and 26pin edge connector on the top of the CPU board. The second board is a Netronix "Multibus PC Network Adapter" card, with an F-type connector. I don't know much about this type of network system except I don't have anything to hook into it. Third card is another one from Intel, labeled "iSBC 576", with another 8086, two connectors on the top, and an SBC576 daughtercard. Fourth card is a PROSE 2000, with a 26-pin edge connector and another connector, and a bunch of EPROMs marked "Speech Plus (c)1983", and yet another 8086 chip. Looks like the company name is Speech Plus Inc. I guess this is a speech synth. The last two cards appear to be memory expansion, made by Memtech, and have a large (50 pin) connector on the top, and "ISBC254S" silkscreened into the board. So, does anyone know what to do with this thing? How do I set it up? What kind of OS does it run? I'm thinking it may have been a repeater controller(I did find this at a hamfest...), which would make sense, with the speech synth being the automatic ID'er. Where do I find info on all this multibus stuff?
