I'm coming to the conclusion that this must have been shipped in the same configuration as Buck Rogers and that it's been converted or attempted to be converted to another game that I can't figure out.
The kickers:
- The monitor is horizontal and front facing, suggesting a 1st person view.
- There is only one start button.
- There is a 2-pin foot pedal wiring (based on a 4-pin harness)
- There is R & L fire buttons.
- The control is digital 8-way.
- The edge connector has solder on n/c pins suggesting it's a potential after-factory rewire.
Buck Rogers has DIP switches that allow it to work in this configuration and it mostly perfectly matches the cockpit Buck Rogers setup described in the Sega manual. In the absence of any better match, I think I'm going to go for Buck Rogers. That said, I'm short of the pedal assembly
