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.
