| 10 | This is a cocktail pinball game, for up to 4 players. The board is round. |
| 11 | When it is another player's turn, the playboard will turn around to face |
| 12 | him. And so, the system has a motor and an infrared shaft-locating system. |
| 13 | If this system does not return the expected data, the machine will refuse |
| 14 | to start. |

| 18 | ToDo: |
| 19 | - Battery backup |
| 20 | - Inputs |
| 21 | - Outputs |
| 22 | - Displays / Layout |
| 23 | - Diagnostic keyboard |
| 24 | - Possibility of a rom missing (most likely it is optional) |
