Hmm, I talked to the ScuzzyGraph people at MacWorld, and what they said
differs from what you say.  First, the ScuzzyGraph system only works with
Macs that do not use Color QuickDraw.  This means Plus, SE, and Portable,
but not SE/30 or later models.  (Does the Classic use Color QD?)

Second, the "color" is based on the old (non-Color QuickDraw) color model,
which is pretty limiting.  Only a few applications display color using that
color model, which means that while 99.9% of the applications will work,
only a small fraction will make use of the color capabilities.

It does use a small amount of system resources, in that there is an INIT
that patches QuickDraw so that the drawing commands are sent to the
ScuzzyGraph box.  (Actually, this should make it *faster* since the CPU
won't have to do all the imaging.)
