- sprites were all blocky, top and bottom of screen had orange background
- Test RAM ranges with Fluke 9010a
- Noted that graphic ROM 2732 @ J1 was put in backwards
- Removed graphics chip @ J1, exact same issue
- Put graphic chip @ J1 in correctly, display had moving lines and "noise" going through it, J1 was probably damaged from being put in backward
- Burned a new 2732 with proper image
- Game works!
