A rear view of the cabinet. On the right is the motor control chassis. In the center is the motor mount, and on the left is the main chassis. The CRT is a 10FP4.

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.
