Why does Bally Lost World activate both the left and right saucer coils to eject the ball from either saucer? Is it because both saucer switches are the same to the MPU? No, they are separate switches in the matrix. Is it because the coils are wired together? No, they are separate coils with different driver transistors and numbers in solenoid test. They always fire one after the other, because as you may know, firing two momentary solenoids simultaneously on an early Bally SS is impossible, by design. Is the ROM filled to capacity, unable to accommodate separate routines for the left and right saucers? I haven't checked but I doubt it.
