This is a reasonably-priced catalogue of most of the mainstream micros available at the time of its writing. There is a new computer release every week (at least). It's therefore important to remember that, with the best will in the world, there is no way a book published can provide a comprehensive guide of this nature. It is out of date before it hits the shelves.

Obviously there is no mention of the new QL, but there is mention of the now defunct Jupiter Ace.

That said, at £1.95, this is professionally edited, and a worthwhile investment - just make sure you supplement your research material with a few current magazines and the sales literature as well.

The meat of the book comprises a two page spread on each of the 76 machines listsed, complete with black and white photo, short blurb, technical specifications and price.

This section is sandwiched between a short introduction on the technologies involved at the front and glossary of terms and list of manufacturers at the back.

If you don't buy it in the next few weeks, wait for an updated edition.
