Sorta interesting (yes sorry for the old thread) but the name on ebay caught my eye. There's a Xerox 6060 (case only) on ebay right now which I was curious as I wasn't aware of Xerox's attempt at a PC compatible. What's more interesting (to me) is apparently it's ALSO the Olivetti M24 (same as AT&T 6300).
I was going to buy a complete 6060 off of eBay awhile back, only to see it purchased a day before I was ready to buy. I have the official documentation and disks for the system, but the actual computer, especially a complete system, is apparently very rare.
And yes, it is pretty much the Olivetti M24, licensed to Xerox
