Quoted from redrock:My score card has three high scores for a free game. How does this work with one plug board?
I'm deducing by looking at a Jet Spin on the 'net and the schems above that you can select scores in increments of 10K only, but you should have multiple '1' and '0' plug wires there to allow you select more than two levels, example 50K, 90K and 130K. I had a Jet Spin long ago but no way am I gonna remember what was back there. Fantastic game too, shoulda kept mine.
