Abstract: A control system for a cinematographic film cassette processor/projector unit. The control system includes a function programmer comprising an operating cycle selector responsive to a processed/unprocessed indicator on the cassette to program the control system for either a processed-film operating cycle or an unprocessed-film operating cycle and a logic unit for programming the sequence and execution of the plural operational modes of the apparatus during an operating cycle. The control system further includes a reel drive control circuit having plural speed and direction drive control modes programmed by the function programmer, a mode change actuator circiut responsive to cessation of film movement to actuate a change in the operational mode of the processor/projector by changing the logic state of the logic disc assembly, and a manually-actuatable replay circuit.
