Hi, I have a set of original DEC manuals for the RT-11 operating system (version 5) that I would like to sell or trade for some interesting calculator stuff. The set consists of eleven large 3-ring and one mini-type orange DEC binders with the manuals inside. The manuals are in good shape, and some are still in shrink wrap. If you're interested, please see a complete listing of the contents at my web site: http://aknight.home.mindspring.com/rt11v5.html I'd prefer a trade for some really cool old boatanchor calculator stuff, but am also willing to sell the set outright. I haven't got a fixed price in mind for sale, a well-thought-out reasonable offer will get the stuff. I also have many more classic computer items available, if you're interested please check out the bottom section of my "trade" page (most computer items are available for sale though) at: http://aknight.home.mindspring.com/trade.htm The list of items I'm looking for on trades is at: http://aknight.home.mindspring.com/wanted.htm Thanks, Alex Knight Calculator History & Technology Museum Web Page http://aknight.home.mindspring.com/calc.htm
