One thing that sticks in my mind are a fair number of S/360 manuals that are obviously not typeset. For example, here the FORTRAN IV from 1965/66:
http://bitsavers.informatik.uni-stuttgart.de/pdf/ibm/360/fortran/C28-6515-6_FORTRAN_IV_Language_1966.pdf Given that the thing is printed in two justified columns per page in a monospaced typewriter font, one can't escape the conclusion that some sort of formatting/word processing was involved. I haven't checked to see if this technique goes back farther than that. But it's a book and it's definitely been processed. Anyone know what was used to do this? --Chuck
