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. > I used to despise HP when they would send updates that consisted of > instructions to modify existing manual pages instead of sending replacement > pages.

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. -Frank McConnell
