- Hardware Notes (guessed):
- ------------------------
-
- CPU: 1x M6809
- Video: 1x M6845 CRTC or similar.
- I/O: 2x PIAs ?? (there is code to initialize PIAs at $8033)

- *** Game Notes ***
-
- RND old notes:
- Game is trying to boot, and after approx. 90 seconds an error message appear
- on screen: "Random number generator is defective", then stuck here.
- See code at $9859
-
- Currently the game spit an error about bad RAM, and after approx 90 seconds
- the playfield is drawn and then hang.
