This independent study course consists of:
an audio cassette containing 10 sessions
accompanying visuals
a workbook containing practical exercises
The purpose of this independent study is to give you an introduction to the ZX81 personal computer. A simple and obvious statement, but it has a number of consequences:
it is a course on how to use your ZX81. It is not an all-embracing encyclopaedia. It aims to give you a basic understanding of what the ZX81 is and how to write simple programs (including graphics) for it in the computer language called BASIC
it is written for non-technical people, so don't expect to get bogged down in a mass of technical information - that's not part of the package!
