It contains a lot of technical information, theory of operation all all the boards, full schematics, copies of the original blueprint drawings etc. Anyone need/looking-for this? Regards, Dave PS: Anyone know what type of system this was used with? -- dave06a (at) Dave Dunfield Billy: We used some of them at Control Data on the Process Control Computers. I liked them; very nice, relieable drums, ran forever. I would love to find one now. Would complement my old timer nicely. And I would certainly like to have the set of documentation and would gladly pay for the shipping. But I'll do something better for the group: I'll happily pay for the shipping to to Al K. so he can put them on his site. Then all of us will benefit from your find. Billy
