While waiting on parts for my dead monitor, I decided to hook my asteroids up to my oscilloscope, and see if I had any video (it plays blind).
On the scope, you can make out objects, but they're pretty screwed up. Flipping it into the test screen, the cross-hatch pattern is pretty much missing. The dip-switch 0's are drawn normally, but 1's cause weird offsets.
I'm not really sure where to begin testing components, so if anyone can point me in the right direction, I'd greatly appreciate it.
