Thanks for all your comments. I'm one of those
mainframe converts who has to learn that there
are things you can do to save money. I assumed
that FAST video memory was used for the entire
screen, rather than just for the current scan line.
But this would make the adaptor cost 10 times as
much.

Also, the AT bus is slow enough to make writing
bit maps to the video adaptor slow. On (expensive)
workstation platforms the bus has 10 times the
bandwidth so this is not a problem.
