In 1981, there were lots of books about the Zilog Z80 microprocessor, which was introduced in 1976, but this particular book was different. With its spine width of 4 cm, you would anticipate around 500 pages of concentrated information, leading to many hours of tedious study of complicated and highly abstract material. But opening the book revealed a wonderful surprise: instead of the expected indigestible microprocessor documentation, what you saw was the microprocessor itself, mounted on a board and ready to use.
