    Making graphics work



    This paper describes some of the operational considerations of a large data processing installation involved in support of an interactive computer system in heavy production use. Application and operating system software has varied over the continued growth and expansion of this system. Mechanisms for user input and feedback, vital aspects to its successful operation, are discussed. The application specifically cited is MCDONNELL DOUGLAS’ CAD/CAM (Computer-Aided-Design/Computer-Aided-Manufacturing) System and highlighted are daily operations of its computer graphics terminals. This system is configured to provide 95% availability with backup switchability features. Typical response, varying with the nature of the user application, ranges from 0.1 to 60 seconds.
