Amstrad CPC 464 User Instructions

This book came bundled with the CPC 464 (although I had to find it separately on eBay as my CPC was unboxed). It's pretty comprehensive and goes far beyond just telling you how to power on the computer and get a picture on the screen. It includes a primer on Amstrad BASIC and loads of nerdy stuff about binary and hexadecimal representations, charts of ASCII character codes, etc.
