The Sinclair Spectrum has revolutionised the world of microcomputers with its ability to offer a very sophisticated colour computer at a price that would have been unthikable just a couple of years ago.

Now Adrian Dickens explains exactly what is inside the Spectrum, and how it works.

Full circuit diagrams and a detailed explanation of each component make it easy to undestand the hardware side of this remarkable microcomputer.

Many features not revealed in the Sinclair Manual are discussed here: how to adjust the colours of your own TV set, how to amplify the sound of the internal loudspeaker, and much more.

Practical hardware projects include how to connect a full size keyboard, connecting the Spectrum to the outside world, and how to build your own joysticks for use with Spectrum.

The Spectrum Hardware Manual is a book that will be an essential companion to anyone wishing to discover how the Spectrum operates or wishing to expand its potential.
