IBC / ICB CPM System

I just saw an interesting system It's a white steel box, about 5 x 8 in and 12 inches deep. Top flips up. Its called an IBC or ICB, I forget, and it's a Z80 based system with a floppy and Micropolis hard drive. I also weighs about 20 pounds due mostly to its antiquated power supply. Any info? It has a CPU card and separate controller card bussed together laying stacked sideways over the drives and power suppy. All the ports (many) are hardwired out the back. I almost picked this up, and I should have. It's going for about 5 bucks. I imagine the PS is shot, I didn't have a chance to check. Is it possible to hook up a standard switching power supply (well that's probably a dumb question). Any clues, I might pick it up, if I don't go to Vegas 1st thing tommorrow.... -Mike
