A Raster-Scan Video Graphics Display System Implemented on a KIM Microcomputer

Abstract

<p> The "microelectronic revolution" and the accompanying decrease in the cost of semiconductor memory has increased the availability of raster-scan graphical displays, yet, as pointed out in a recent survey [BAE79], the implementation of graphics software for raster-scan systems has lagged behind that for random-scan systems. The aim of the work described in this report has been to apply random-scan display techniques to a system employing a relatively inexpensive raster-scan device. The system, incorporating a segmented display file processor, is implemented on a KIM^TM microcomputer. The display device is composed of a Micro Technology Unlimited^TM (MTU) 8K Visable Memory^TM (VM) video board and a standard TV monitor.</p>
