XS-0

Abstract

XS-0 is a low-cost interactive system that serves as a self-explanatory school computer. Particular attention has been devoted to making the man-machine dialog easy to follow for the inexperienced user. The system includes a course on computer programming, a programming system for writing, editing, executing, and debugging programs interactively, and a filing system containing private and public libraries. The language offered to the user is a version of Pascal. The system is realized on a small stand-alone computer which supports a small number of graphic terminals. This hardware consists of the most cost effective components currently on the market.
