Adding the date would be relevant - the linked document is from 1961!

Concepts like the ones described in the "Extended Machine Operations" and "Pseudo-operations" sections (start around page 16) are a lot more impressive in that light; designing a system for expressiveness and programmer convenience over pure utility was still a very new idea.

Impressive page layout for a paper from 1961!

It's a printed manual. They did have typesetting back then. I like the wide margins with subheadings in them. I bet a lot of copies got written in.

It was probably typeset by typing it on an IBM Executive typewriters which had proportional spacing and a carbon ribbon.
