I have a web page (<http://www.cs.ubc.ca/~hilpert/e/gates/index.html>)
where I'm accumulating the diversity of symbols that have been used for
logic gates. If you have a scan or reference for the Cray/6600 symbols I'd
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.
