I have two SGI Challenge XL racks going up for grabs; I really need the space back for other new equipment. Make an offer, mostly just want the space back, and I don't really have a use for another big old Irix box.. One is an R10k system and one is an R4400 system. I don't remember exactly how much memory and procs are in each, but could go look. They both have 10BT ethernet and FDDI connections. Pick-up is preferred, from Lafayette, IN. Zip 47901. If you want me to ship the machine, expect to pay for my time and effort to do so, in addition to freight charges. If I don't get a response by Feb 3rd, I'll be parting the machines out to sell on ebay.
