While it's true the Apple ][e 80-column board is slow, I think
this is because the scrolling is done in software.  Sean Kamath
pointed out that the monitor ROM's in the enhanced //e help the
system scroll faster.

However, in reading the Softerm II manual, I find that most other
80-column cards for the Apple use hardware scrolling, which I
understand is MUCH faster, and able to keep up with higher-than 1200
baud rates.  I think most of these other cards are normal-clot cards,
rather than auxiliary-slot cards.  Since I haven't used these, I can't
tell first-hand what the speed increase looks like.
