Does anyone know how the new bigger screens do memory-mapped i/o without bus
arbitration? I assume they still use memory mapping because I doubt they
have written their own QuickDraw modules. Obviously, there are a number of
approaches possible in the add-on hardware.
Also, I would be interested to know what real improvement in performance is
gained by this trick. There might be up to a factor of 1.5 or so, but I
wonder whether most applications aren't largely disk-bound rather than
compute-bound.

Bibliolatry is my bizarreness.
