Computer Control of a Random Access Slide Projector.
Barker, Philip G.
Microprocessing and Microprogramming, v10 p261-271 1982
A description of a simple interface to enable the interconnection of a random access slide projector and a microcomputer is provided, as well as summaries of the role of slide images as a means of implementing graphic communication and the new activity in graphics as an area of information processing. The microcomputer interface is then detailed, including limitations of the technique and suggestions for improvement. An analysis of applications of the interface focuses on multimedia computer assisted instruction systems, implementing automatic slide display systems, and implementing graphic interfaces to information systems. Figures illustrate the computer controlled slide projector, the function of a manual slide selector, design of the interface, switching element circuit details, and memory mapped random access slide projectors. Tables show an example of an interface control program written in BASIC and present a program for automatic slide projection. Fifteen references are listed. (LMM)
