Designed with slide rules and drawn with pencil on vellum.
Bill of materials kept by some ancient clerk with 3-ring binders.
How the heck did we ever do it, LOL?

Tell me about it. Well, one reason was because people could think - the computers were in their brains. A slide rule was all of the help they were going to get. If they needed to add up two numbers, they got a pencil (definition: a narrow, generally cylindrical implement for writing, drawing, or marking, consisting of a thin rod of graphite, colored wax, or similar substance encased in wood or held in a mechanical holder) and paper (definition: a material made of cellulose pulp, derived mainly from wood, rags, and certain grasses, processed into flexible sheets or rolls by deposit from an aqueous suspension, and used chiefly for writing, printing, drawing, wrapping, and covering walls) and wrote down the numbers, and added them up by hand.
