# representation of electrical circuits (paper)

I'm looking for an old paper about a format for representation of electrical circuits using text, similar to some of the current netlist formats. Here is what I remember:

• it was written by Richard Stallman and (Gerald Sussman or Hal Abelson) from MIT;
• circa 1970 (with big error margin);
• it focused in writing software that solves electrical circuits in Lisp;
• it was likely typed using a teletype;
• it describes a simple yet effective language for representing analog electrical circuits.

• That's old technology. Are you able to use something like Visio? If you wish to use a programming language, look into Circuitikz that's a package for $\LaTeX$. – KingDuken Oct 9 '19 at 18:43
