this is the most astonishing thing I have read in a long time and I am CS not electrical engineering, so I have no idea what these drawings mean. I speak german, but I hope something works to translate this easily, as it is absolutely crazy. I did not know something like this was possible back then.

It is astonishing how advanced the world was back then...if it wasn't for this use though

I would say understanding of the paper depends more on having an electrical engineering degree than a CS degree. The diagrams look to be electrical circuits and signal diagrams (I am not sure what is the correct term but for example 'Abb. 10a' in the article) mostly.
