Joust CPU problem

My joust is now doing this http://www.basementarcade.com/doubejoust.JPG
The bottom half of the screen is repeated on the top!! The test screen
passes all the rom, cmos and only gives a error on one screen prior to
the color bar test that states something like "vertical bar error" or
something like that. Any ideas as I have exhausted all the William's
tech pages I could hunt down.
