OFFERED: IBM "Mainframe"

. I have an IBM computer that was used to run a local oil refinery. It has two cabinets (62"H x 36"D x 26"W) that I'm guessing weigh somewhere around 250 pounds each, three terminals (one appears to be "smart"), a few misc pieces of network cable (not Cat5, some kind of coax) and what appears to be a network hub. Approx 10 feet of manuals. . One cabinet is marked: Type 9309 S/N 10-0046692 and contains a 3/4" (maybe 1") mag tape drive (quite a bit of damage to the door, but the transport looks OK) and five PSUs (220VAC in, not sure of the out specs). The rear door is marked "9309 2" . The other cabinet is marked: Type 9309 S/N 10-0074115 and contains a 10" floppy and what appears to be the CPU. . That's everything I know about it. If you can tell me what to look for and where it is on the unit, I'll look for it. . I've never seen it powered up, so I have no idea what, if anything, works. . Located in South Arkansas, US. You must pick up. I will not deliver nor arrange for delivery. It was delivered in a "standard" pickup truck, but the springs were sagging a bit. . Would like to trade for something useful, but will consider free-to-good-home. . Please remember that this thing is huge, heavy, and not much use as a computer (I had dreams of using it for "home control" eg, HVAC, security). If you don't have the resources to come get it, please don't ask questions, 'cuz I've already told you all I know about it.
