If you have a scan or reference for the Cray/6600 symbols I'd be interested in adding them. --------------------------- I'll be glad to if I can find one over Christmas. I'm flying to the Bay area on Saturday, so I'll look next week. I know I have the plastic drawing guides for the 1604, 3000 and 6000 logic symbols. And I think I have some scans of the legends of several schematics I'll send you. But my all time favorite was the logic drawings of the Bendix G-15. They were drawn by an artist. Every page is clean, neat and easy to read. Lots of comments. I still think they are the prettiest schematics ever produced in the industry. Even if it was a valve (vacuum tube) machine. The ugliest, hands down winner, are the IBM early machine drawing schematics or logic manuals for the System 360. They were done by a badly timed line printer with an exceptonally bad ribbon. Billy
