This book, part of a Penguin series, takes whole chunks of text word for word from its sister publications, though in some cases they are unsuitable for it.

Large paragraphcs of small type and too few sub-headings make it difficult to find information. There's no index and content is muddled. Information about Basic is fragmented and, for instance, the section on program writing contains hints on cassette handling. The chapter on "How the computer works inside" is sadly condensed to the point of confusion.

The sections directly relevant to the Dragon, such as those on sound and graphics, are useful but rather short, while the question and answer style program exercises are good but truly useful illustrations are sparse.

Quite what Penguin intended this book to be is difficult to guess. It isn't a reference book and it isn't easy reading. At £4.95, this is a luxury Dragon owners might not miss.
