This covers the well-trodden "introductory guide to the Sinclair Spectrum and Basic" ground, taking the computer newcomer on a programming course up to the level of do-it-yourself programming projects.

It's a meaty book. After preliminary pages which go back to grassroots ('micro-circuits are known as silicon chips....' and so on) it gets down to business with diagrams and technical details.

It has the added bonus of about 50 program listings for the Spectrum covering a range of applications, such as word processing, stock control and three-dimensional plotting.

If you want to use your Spectrum as an introduction to programming, this would be a useful addition to your library.
