The Triad TC-3550 PCB assembly is a complete micro-processor system, including EPROM and battery-backed RAM memory, serial and parallel I/O, and a data buss interface on a single board. This card is the heart of the LDC/SCU (Laser Disc Controller/Show Control Unit) as well as the STU (Servo Terminal Unit) and DTU/RTU (Data/Remote Terminal Unit) card frames. A modular front panel connector is provided for local terminal access for setup, calibration, and diagnostics. The function of the TC-3550 is defined by the firmware in EPROM and the associated hardware in the card frame.
