But that is how traditional Apple II 80-column cards worked -- they
had their own video output that you had to attach to another monitor
or switch back and forth by hand. The spiffy ones had a switch to
flip back and forth, or the *really* spiffy ones could even do it
in software. But it was only with the IIe that the 80-column video
started to be automatically a part of the internal video output.
Before that, the card might as well have been a terminal attached
to a Super Serial card.

Debugging.
You can run your program on one screen, and have debugging
output/debugger output on the second screen. I did that once on a PS/2 when
I was writing code to manage the 8514 display. It was very nice to see not
only the output, but have the debugger not munging the display.
You couldn't do that on an Apple. It only had one video output. Unless
the 80-col card in question had a seperate video output. And then you'd
have to go back to that clever programming thing.
