The other one that sticks in my mind was a standard for imperial screw threads. It had last been published in the 1940s and hence no electronic file of existed so I had to create one. It had a table in it that listed various dimensions of the pitches that had such obscure measurements as 3 15/16 inches so much use of the equation editor was required. The table was designed to be a foldout insert so was huge. And we were using Windows 95, P1s and 14" screens so crashing and locking every two or three minutes as the machines couldn't take it. Tell kids that today and they won't believe you.
