Design a Z80 Computer - J. S. Walker - Bog

In July 1976 a new type of Integrated Circuit was released into the world and over half a century later it is still in production. This device is the Zilog Z80 processor and its longevity surely makes it one of the most successful electronic devices ever produced.
This device spawned the rapid development of multitude of relatively low cost personal computer systems which would previously have been impossible to produce.
This book is aimed at anyone who has ever wanted to design their own Z80 based computer system. From first principles to a fully working computer it delves into circuit design at the discrete logic level. Each circuit is fully described in detail and although this computer has many of the features found in many vintage computer systems it avoids the use of large scale integration devices. Each circuit is constructed using discrete logic gates to provide a fully immersive development experience.
