I have gotten an LAI asteroids cocktail in for repair, it looks like the 'Meteor' bootleg board set, that is basically the normal asteroids board but in two pieces, with the deflection board and logic boards connected via ribbon cables. The machine powers up and the voltages for 5V and +15V and -15V are all correct, but I get just the pinpoint of light on the monitor. There doesn't appear to be a test-switch on this cabinet, does anyone know how to activate test mode on the boards?
