Design a Z80 computer

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.

has spent many decades running highly successful companies which initially specialised in the development of cutting edge embedded systems for critical applications. As his companies technologies developed and spread world wide he also became instrumental in the creation of validation systems and protocols. His companies became world leading in the development of cold chain management products and applications including global mapping for the support of medical directives and standards.Following retirement he has returned to working on vintage electronic and mechanical systems of all kinds which is how his career started. He has written several books on these topics including how to build a complex microprocessor from discrete transistors and another on how to design magnetic core memory systems.He currently undertakes no charge repairs of vintage machines for collectors and enthusiasts while also creating reproduction boards and components aimed at keeping these old devices operational.
