Going through the crap I have in the basement, I ran across a few manuals for an old Unisys unix box I used to have (until my parents moved, and left it behind). If anyone is interested, I'm asking $5 each + actual shipping cost. U5000/20/30/35/40/50 and /55 Systems U5000 Series Operating System -- Installation Guide UP-12693 Rev 1 -- Planning Guide UP-11768 Rev 3 -- Programming Guide UP-11221 -- Installation and Planning Guide UP-12694 Rev 1 -- User Reference Manual Volume 2 UP-11760 Rev 2 Those are all in binders, complete with the black case-thing to make them easy to stack on a book-shelf. All in good condition. Contact me off-list if interested. Thanks -- Pat
