|READ CHAPTER TWO FIRST!
This book is the user's manual for the ZX-80 personal computer. In it is everything you need to know in order to set up the ZX-80 hardware and to use the ZX-80 BASIC language for writing your own programs.
For most of the book the chapters are grouped in pairs. The first (odd-numbered) chapter of a pair is purely descriptive and prepares the reader for what is covered in the second (even-numbered) chapter of the pair. The second chapter of a pair is intended to take you through the use of ZX-80 BASIC as painlessly as possible while you're actually sitting at the keyboard.
If you are an experienced BASIC user, you won't need to read very much — probably only chapter 2. the ZX-80 BASIC language summary, and the Index.
If you're less experienced and patient, it's probably best to read through the whole book, chapter by chapter. If you're less experienced but impatient you can skip the odd numbered chapters 3, 5, 7, and 9 (and probably will!).
OK. NOW READ CHAPTER TWO - AGAIN!
