SparWeb,
Thanks for the suggestion, but I already tried that and didn't find what I was looking for. Back in the day, before PLC's became popular, people would draw the ladder logic in CAD. I was hoping someone might have a drawing similar to that.

I have to start there, when the question doesn't make it clear that the elementary steps have already been tried. To me, there's nothing wrong with a graphic like this-




Do you mean to emphasize the "OLD" look of the drawing? hand-drawn? dog-eared photocopy? stone tablet?

I guess what I mean is a drawing of how one would wire actual "Relay Logic". We used to number the rungs, number the connections, etc.
I do appreciate your thoughts on the matter however. I'm not sure I'll every find exactly what I'm looking for.

By the way, what did you use to draw that? It looks like a software drawing or simulation package as opposed to Ladder Logic program from a PLC.

what about this

If You need translation of few pages I can do.
Furthermore photos and video are available : just ask

DM,
I didn't draw it. It was about the 5th line of the google images result. Seriously. There's a URL watermark on the graphic - check it out, see what you find.
I have played around with variations of "Spice" (there are many). The objective of spice is to simulate an electrical circuit under continuous or transient conditions. Typical packages now include graphical circuit sketching interface, and a library of common electrical devices, from switches and relays to 555 IC's. But this, again, is the modern style of circuit design.

Since you're looking for something more "retro", maybe you could try an old textbook or two.
