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.

. Bump. . If no one is interested, I'm going to have to junk it. :(
No, no, no! *cries* I'd love it...but can't get it and have nowhere to put it...

. At this point, I'd be willing to let anyone have any parts off it that they want to come and get. The power supplies alone should be worth the trip. Or the cabinets.
:( If only I could...what I wouldn't give to be able to...

> sounds like the rack number for the RS6000 . Your guess is as good as mine. Probably better. . > either "thinnet" or "thicknet" . It's not the same coax that is used for cable TV, it's more like the stuff that hams use (about twice as thick). Definitely not twin-ax. . > I bet you could use it as a heater . heehee I haven't seen it powered up, but, yeah, I bet it could keep me nice and toasty on a Winter day. My Pentium D system (CPU alone is 90+W) keeps the room it's in 2-3degF warmer than the rest of the house.

The number you mention, 9309, sounds like the rack number for the RS6000. *shrug*

the coax network cable you speak of is either "thinnet" or "thicknet" thinnet or 10base2 transmitted at a speed of 10Mbps over a distance of ~200 meters. thicknet or 10base5 transmitted at 10Mbps over a distance of ~500 meters. its also much much larger than regular coax cable, and i would hate to run the stuff through a building. i think i got those right... maybe you could sell the individual parts of them on ebay? if the power supplies were 120v i may be able to use one of them.

Not sure about using it for "home control", but I bet you could use it as a heater... ;)

Good grief! Do they have tech/science museums in your area? They may welcome a donation...

Yes, that is where we sent out IBM 4381 once we migrated to the AS/400, along with the card reader, interpreter, card sorter, and keypunch machine (yeah, we used them up until about 10 years ago, if you can believe that).
