Sorry, I should have stated that  QuickDraw is too slow for what I am trying
to do.  I WANT to get around its slowness by drawing directly to the frame
buffer.  I can do it on a plus.  Does anyone know how to draw directly to
the frame buffer on a Mac II? Any suggestions welcome and appreciated.

E-mail is fine if the general audience is not interested.
