I have found that greyscale programs will run on a turboed calculator if
the batteries are near dead, but they are still too fast to be playable.
This is a problem that might be fixed if someone were to write a greyscale
de-turbo program for USGARD (I  think I remember reading that USGARD
supports "chaining" of interrupts, which would make this possible (before
it was not possible))  I might take a stab at this someday, it shouldn't be
that hard.

Correct me if I am wrong, but the pages are flipped at exactly the same
rate on a turboed calculator as on a normal one, for the same reason as
ZTestris runs well on a turboed calculator, they are both interrupt driven
and the frequency of interrupts is the same on both turbo and normal
calculators.  So this is not really the problem, it is just that the
instructions are being executed too fast, as is the problem with normal
black and white programs.
