What's a "computer console" selectric called?

[Chuck Guzis]

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?

Even these "programmer's manuals" were superbly done, when compared 
to some of the Univac documenation of the same period, run off on a 
badly-timed drum printer (made my eyes hurt to read it).
