This thesis concerns the implementation of the CORE GRAPHICS SYSTEM on the ZENITH Z-100 microcomputer, using the MS-DOS operating system and the MICROSOFT PASCAL programming language. The system gives the user the ability to create graphic displays via computer utilizing either a printer or a CRT. The basic features of the system, the problems encountered in its implementation, the general principles used, and an operations guide are documented within the paper. There are programming examples to illustrate the usage of the different system commands and there is documented source code of all system subroutines.
