The investigation is a phase of a broad continuing effort to establish an in-house capability in microelectronics technology and to determine where and to what extent microelectronics should be employed in equipments and systems in the Fleet. It was decided that as a pilot study, some representative logic function would be constructed, with qualified manufacturers given the assignment, under contract, of furnishing the required circuitry. The study vehicle chosen was a binary-to-decimal converter designed to accept straight binary coded data and convert them into binary coded decimals suitable for driving decimal readout devices. The converter is capable of decoding simultaneously two 12-bit words coordinates X and Y transmitted from a device which simulates realistically the transmission of coordinate data words between the NTDS unit computer and the display consoles. This logic function seemed especially suitable for the investigation, since it involved six decimal decades, each of which could be implemented with a different type of microcircuitry. Author
