roll out the bandit

This oscillator was designed for driving electronic games of chance, such as the `three-eyed bandit` (Elektor No. 2 page 238) or an electronic `roulette wheel`. The disadvantage of the `three- eyed bandit` is that a stop button must be pressed to stop the three oscillators and obtain the final display. Thus the tension and anticipation obtained with a real one-armed bandit as the number drums slowly grind to a halt is missing. The voltage-controlled oscillator overcomes this by pro- viding an output whose frequency slowly reduces until it finally stops. This can also be used to simulate the `rolling out` of the ball in a roulette wheel.
