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.
