MASSACHUSETTS INST OF TECH LEXINGTON LINCOLN LAB
Pagination or Media Count:
The Haystack Pointing System, implemented on the Univac 490 computer, is comprised of some thirty odd subprograms which go to make up an operating system and a utility system. The domain of this memorandum is limited to the description of the control of the operating system as vested in the master control and timing programs and in the computer itself via its external and internal interrupt capabilities. In the discussion of the programmed control function are included the real-time and simulation modes of the system, the man- machine communication scheme, the experiment set-up procedures, a step by step description of the entire system cycle, the plug-in program concept as utilized in connection with the celestial computation programs and data processing programs as well as other system facets as they relate to control. Certain procedural matters which bear on the control structure are discussed.
