It is possible to write a complete 80 by 25 page full of information on
a slow 4.7 mhz PC to a snowy colour card in 1/15 second by waiting for
retrace, and thus getting no snow.

I wrote a curses library package ages ago that's used in some of my
software packages that does just this.  1/15th of a second is just
barely noticeable.  You can't notice anything on a machine faster than a
PC.

No fancy bank switch schemes are needed, just good retrace waiting code.
