I apologize in advance if you received this twice. I got an error message the first attempt and I am reposting it. I just picked up an old and neglected Xerox 860 IPS system. It came with a mess of spare boards, most marked bad, and a box of original Xerox disks. Problem is I can't get it to boot any of them. Is there someone on this list that could send me a known good one so, I have a place to start from ? I don't really care what it boots as long as it boots to something on yours. I've done all the customary re-seating of everything and swapping boards around but, the boot result is the same. Even with all the boards swapped out with spares. Everything is pretty clean inside. No leaking caps or frayed wires. Connectors all look good. I've read a couple entries on various pages claiming this was not really a computer but, a word processor that ran a custom OS. Mine came with original Xerox labeled CP/M disks along with COBOL, Visicalc, dBase, and Wordstar so, someone had to be using this as a more general purpose cp/m box. It also came with a Xerox Word Processing system disk that attempts to boot as well. It loads for awhile then just stops and does nothing further. The CP/M one boots for a bit then prints C to the screen like perhaps it is printing out the CP/M banner and dying after the letter C. the front display just read 0000 which I think means no errors. I have no idea if the keyboard works. Appreciate any thoughts. Thanks.
