AN EXECUTIVE SYSTEM FOR A DEC 339 COMPUTER DISPLAY TERMINAL
MICHIGAN UNIV ANN ARBOR
Pagination or Media Count:
This report describes a real-time multiprogramming software system for a DEC 339 computer display terminal, which may communicate with an external computer through a serial-synchronous data set. The system is designed to support both programs which require the attention of an external computer while they are being executed and programs which are independent of external computation service. For either type of program, the entire graphics support is provided by the 339 system, but the interpretation of the relations implied by the graphics may be performed either in the 339 or in an external computer. Multiprogramming facility is provided to facilitate effective use of IO devices in order to cope with the demands of a real-time environment.
