Implementation and Evaluation of a Core Graphics System on a VAX 11/780 Computer with a UNIX Operating System.

Abstract

A Pascal Core System using the VAX VMS 11/780 operating system from the University of Pennsylvania was converted to run on the Air Force Institute of Technology (AFIT) VAX 11/780 UNIX operating system. Major problems in converting from the VMS operating system to the UNIX operating system were encountered, but they were solved and documented for others to use and avoid. The size of the Pascal Core System and its lengthy compile times were a major system limitation. Device drivers were written in C for the Visual 550, the Tektronics 4014, and the Hewlett Packard 7220A 4 color plotter and can be applied to other projects. The Core package that was converted follows the SIGGRAPH 1979 standard. An application program, called intcore.run, is available that demonstrates the Pascal Core routines that are supported by this system. (Author)
