I got the original PCB for this game and was playing a bit. Turns out there is a dip switch position for "No Hit" so you can basically have a trainer mode with a flip of the switch. I finished the game a couple of times and I noticed that every time that I finish a dragon shows up right below the TIME left. I finished the game 4 or 5 times but looks like 3 dragons is the maximum. Anyone knows anything about that?
