Good point--there's nothing so quick as a hardware-controlled
data transfer.  ;-)

Since I use 3.5" diskettes on several Apple II's, most without
Superdrive cards, I never changed the interleave.  In fact, I
usually interleave for the //e's instead of for the faster IIgs,
since the downside of IIgs interleave on the //e is so much
worse than the reverse situation.
