Something that has itched at the back of my mind for
decades, related
to this topic:
What was used to produce many of the S/360
"programming" manuals? An
example is the DOS F-level assembler:
These are clearly typewritten (not typeset) in a
monospaced font. My
own copy dates from a couple of years earlier (than this 1968 copy)
but has a similar appearance.
Anyone know for certain?
They were done using an IBM 1401-N1 with a TN print train, which provides
upper- and lowercase Courier (or something very much like it) in an EBCDIC
encoding. This was used to produce camera-ready copy which was offset
printed in IBM's own print house (supposed at the time to be second in
capacity to the US government's printing operations).
Or at least that's what I was told by an IBM SE ~40 years ago.
