Speccy Nation
Back in the 1980s I was an enthusiastic owner/programmer of the ZX Spectrum, my games "Bod and the Vampires" (jointly written with Richard Notman) and "King Penguin in London" were never published but there were many good games released from both big and small publishers.
Speccy Nation looks at the best of these such as Sabre Wulf, Skool Daze and my favourite the super fast Death Race 2000. It also looks at some of the less popular titles that had unique UI elements or otherwise pushed the boundaries of what computer games were at the time. It's a great book for reminissing or for study. Dan Whitehead's observations and comments reflect some of the humour of the time and it's clear that he's done a lot of research. The book finishes off with some links to popular emulator sites and archives. Definately worth getting hold of.
