I just picked up a Asteroids Deluxe and noticed that the asteroids and ships would distort at different points in the screen.
I ran the test mode and could see that the diagonal lines are not perfectly straight. They wave at different points.
I found this troubleshooting note on the web:
Symptom: (Asteroids Deluxe) Everything except the linearity of the displayed image is correct. In the diagonal crosshatch test pattern, as the lines go through the horizontal center of the screen, they become skewed in the up-down direction. While in attract mode, as the asteroids cross through this area, they become elongated, stretching out in the up-down (Y) direction. This problem was caused by a failing resistor, R124, 8.2K - this resistor had changed value to approximately 13 K. Replacing R124 corrected the irregularities.
It sounds kind of like the problem I'm having. Can anyone confirm?
Thx,
Tim
