A special-purpose digital computer has been developed using the new ECS LSI microprocessor technology. The primary gcal of this work was to solve a fairly complicated computing task using a minimal amount of random logic and limited development time. This computing system solves ships' maneuvering board problems including the deter ruination of course, speed, and closest point of approach cf other ships. Ten contacts can be tracked simultaneously. The triangula tion involved in these calculations is performed using a decimal version cf the COREIC algorithm. A complete maneuvering situation can be computed in 4.5 seconds. Except for hardware required to drive the displays, all logic is contained in the software-encoded read-only-memory chips, which drive a single CPU chip. Approximately eight hundred man-hours were required to develop the programs and prototype the hardware. The system is modular and easy to maintain, low in bulk, power consumption, and cost.
