The DEC VT100 terminal had an 80x24 display.
So did the VT52 before it. One of the innovations in the VT100 was it also
had a 132-column mode. In this mode, the number of displayable lines
shrank to 14, as I recall; unless you had the extra-cost “AVO” (“Advanced
Video Option”) addon, one of the features of which was enough video RAM to
keep displaying 24 lines in this mode.
It was not really a comfortable mode to use. I kept thinking something was
squeezing my eyes together ...
Punch cards have a longer history than you might think.
Right back to about 1804, in fact. Trivia question: what were they being
used for then?
