I am having trouble understanding how the three memory areas
that make up the tv picture fit together. There is the
VIDEO MATRIX (1024 locations), the COLOR MEMORY, and
the CHARACTER MEMORY. Can anyone explain to me how these
fit together in bit mapped mode? For example, what do I
do to put a red dot on the screen? Any help (especially
a reference to a better explaination than that in the
Programmer's Reference Guide) would be appreciated.
