Asteroids blues

  Thanks to Drew and Simon for your suggestions with my Asteroids
troubles.
As far as the Reversing X output goes, I still have not been able to
accomplish this.
Swapping the wires (orange and black X output to monitor) didn't work
(blank screen, spot killer on ). 5 volts at pin 19 reversed the Y
(vertical) output, so then my screen was upside down and backwards. 5
volts at pin 16 (reverse Y on asteroids deluxe) yielded nothing. There
must be a way of reversing this at the monitor?

  My other problem was a ripple effect as vectors move horizontaly
across the screen. I don't have a scope (yet) so I haven't been able to
try Simons suggetions. I did determine that the problem is on the game
board. When looking at the test pattern the diaganol lines have a slight
jog in them about every centimeter. sort of a saw tooth pattern instead
of a straight line. Anyone familiar with this problem?

Thanks
Jason Milsom
