Maybe the fact that the system would work on displays of any resolution?

30 years of GNU

No, this was 1983. People did work on terminals, and those terminals came in an unbelievable number of varieties. There was a period of time where you could determine people's relative status by seeing who had a vt100 in their office, and who was pounding on an ADM3. Making software work transparently on all those terminals was a real challenge, to the point that the original curses library was actually a significant contribution; rms was certainly thinking about the continuation of that work.

There must certainly be some old /etc/termcap files out on the net. Reading the comments found therein used to be a way to get a, shall we say, graphic description of just how annoying some terminals were...

Kids these days have no culture...:)

We had an old Unix machine (I forget what variety) in our department where I was a student in the mid 1990s which came with five terminals with green plain-text screens (VT100 compatible). It was kept in the common student area but we had at least one professor who would only ever use those terminals for sending email (he used computers for little else), because he didn't know how to use these newfangled window-based thingies. Alas, the machine was eventually retired...

Even as late as the early 90s (when I joined the UNIX scene), we still had quite a mix of terminals and terminal emulations that made curses and proper TERMCAP settings very important. At the university I attended, I encountered, among other things:

  • An actual DecWriter II (although I never actually saw anyone use it).
  • Viewpoint terminals (both Viewpoint and VP60s)
  • Liberty Freedom-1s
  • AT&T 620 (layers based!)
  • UNIX-PC / PC-7300s
  • Console mode on Sun IPCs, ELCs, SparcStations, etc. (Anyone who stayed in 'console' more than a minute, though, generally got nastygrams from all other users logged in in short order, since display updates in console mode blocked proper multitasking. Launching ELM at console guaranteed you more than a few angry messages.)
  • Console mode on 0.99.x era Linux
  • A plethora of terminal emulators across DOS and Windows (Kermit, Minicom, QModem, NCSA Telnet, MS Telnet, etc. etc.)
  • Subtle differences between xterm variants (persists until this day).

I guess the main difference by the time I got there was that everything was shifting to terminal emulators on PCs and Macs as opposed to dedicated terminals. We still had many dedicated terminals, but by the time I left, most everything was on a PC or Mac in some form.

Amazing, just noticed no /etc/termcap on my ubuntu system, stty is still there :)

By chance at this very moment I am looking at a 2 page "Data Processing Master Plan" from 1984 for our college which surfaced during office reorganization today. The document brags about the DEC 11/70, the number of student terminals, a possible upgrade to a VAX 11/750, going from Fortran IV to Fortran 77, adding another operating system "such as UNIX", and replacing the terminals with microcomputers.

I think he was actually talking about serially-attached terminals (vt100/vt220/etc.) and something like terminfo to support text output on all types of terminals, where software doesn't need to be written with a specific terminal (later: terminal emulator) in mind.
