I am having trouble with modifying the display list to mix graphics and text
modes.  Specifically, I have written a slot machine game using the PM Animator
software.  I poked memory locations used by the display control chip to put
some graphics mode 2 lines in a graphics mode 7 field.  The program works fine
on my 800 using a monitor for display.  If I use a normal TV the display rolls
vertically.  Question;  Am I sending too many lines to the display chip?  Is
there a memory location to control the number of scan lines sent to the display?I believe the monitor just ignores the extra lines.
