The folks who did the 3000 manuals didn’t do that very often.  What we
got were almost always update packets that simply replaced pages in their
manuals.  Once I think I remember getting a sticker to be stuck over the
replaced text on a page.

The 3000 folks I think had to make some effort to get beyond paste-up
to where they were doing their manuals and updates in something, and it didn’t
happen until the not-so-early 1980s.  Sometimes I thought the thing was
TDP/3000 and the camera-ready copy came out of a 2680A or 2688A printer.  I
don’t really know how they got there or how it worked, and by the end of the
1980s I think they had moved away from TDP/3000 to something else.
