Yep, that's the sort of pager I imagined would have been present on all
terminals. I can't imagine how people coped with using `ls -l` in
directories with more files than their screen had lines (unless one was
fastidious with their use of grep(1)?) It just feels unrealistic for a
terminal not to have a pager. Then again, our TTYs these days have
full-screen editing, 24-bit colour codes, Fraktur lettering, and God knows
what else I'm forgetting...

Back in those days, terminals ran at 30-240 characters per second. Not all that fast. Actually 300 characters per second, i.e. 300 baud, was slowww!
I remember being blown away by 9600 baud terminals.

The 'coping mechanism' was that one pretty quickly became adept at using CTRL-S/CTRL-Q to stop/start the screen display.
