sheesh, some threads just won't come to a conclusion and die :)

this is all a VERY long time ago.  the development of a 
screen-addressable editor (vi, which started life as an extension mode 
to ex) at UC Berkeley became possible basically because of the ADM 3A 
(yeah, it's got its own wikipedia page: 
https://en.wikipedia.org/wiki/ADM-3A)...   Slightly more advanced 
terminals like the VT-100 and an HP model (26something, I don't remember 
the code number) and some Beehive model turned up and suggested 
generalizing the cursor-addressing functions, which is where curses came 
in.  I was a student there at the time.  The 3A was funky, as I recall 
the Beehive was even more funky... and there's really no reason to hang 
on to quirks from those early days, since all "terminal" behavior is 
emulated now....
