You must be pretty new to csa2.  In csa2, folks get to know
that David Empson is a genius and an oracle with respect
to the Apple II.  He is a vast storehouse of knowledge and
can whip up a program to do or fix things out of thin air in
no time.  He's also polite and helpful, which is refreshing
as some folks who used to have lots of knowledge and
used csa2 had mean streaks.

David Empson is a model csa2 citizen.  I always enjoy
reading his posts.  ;-)
