    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.

    Magnetic Core Memory Decoded is a detailed work describing the operation and development of a magnetic core memory system of the type originally implemented in the 1940's through to the 1960's.Core memory was a major stepping stone in the development of modern digital computer systems and is a fascinating technology which encompasses many engineering disciplines.A full explanation of the technology is provided from the basics of magnetic core flux responses through the design and implementation of circuits required to create a fully functional memory system.The system presented in this book is a non-trivial design and while it is relatively small in terms of its storage capacity it is still large enough to give the reader a full account of the technology and the amazing secrets of this technology.This book is a must for anyone interested in the history of computing or is simply interested in the development of engineering technology.
