I was a tech writer at IBM in Austin, TX in the late 80s. We were writing documentation for the RS/6000. I loved the publishing software we used and was sorry to see it replaced in the marketplace by cheaper, less powerful software geared towards desktop computing. There was a complex set of context menus that enabled you to work your way through a document incredibly quickly once you mastered the software.
I think the company was located in MA?
I'm trying to remember the name of it. I can't find it anywhere! Does anyone remember this software?
I don't remember what we worked on... Maybe proprietary computers? It was definitely not Windows or Macs, which were not powerful enough in those days (did they even exist? No idea).
I eventually became a Unix sysadmin, inspired by my experience with that software. In using it I found that I preferred the "technical" part over the "writing" part of "technical writing".
