Here is the motor mount. In the front are two clamps for the starting capacitor. Directly behind is a frame for the motor, which was mounted behind it with the shaft facing forward. A belt drive was used to connect the motor to the color wheel shaft (above), which has the alternator (used to generate a signal for motor sync) mounted on it.
The controls are hidden by sliding metal doors.
