Hardback. Zustand: Good. At last - the secrets of Bletchley Park's powerful codebreaking computers.This is a history of Colossus, the world's first fully-functioning electronic digital computer. Colossus was used during the Second World War at the Government Code and Cypher School at Bletchley Park, where it played an invaluable role cracking enemy codes. Until very recently, much about the Colossus machine was shrouded in secrecy, largely because the codes that were employed remained in use by the British security services until a short time ago. This book has only become possible due to the recent declassification in the US of wartime documents.With an introductory essay on cryptography and the history of code-breaking by Simon Singh, this book reveals the workings of Colossus and the extraordinary staff at Bletchley Park through personal accounts by those who lived and worked with the computer. Among them is the testimony of Thomas Flowers, who was the architect of Colossus and whose personal account, written shortly before he died, is published here for the first time. Other essays consider the historical importance of this remarkable machine, and its impact on the generations of computing technology that followed. …

Hardcover. Zustand: Very Good. 480 pages. library sticker on spine - no other markings, private collector The American ENIAC is customarily regarded as having been the starting point of electronic computation. This book rewrites the history of computer science, a rguing that in reality Colossus--the giant computer built by the British secret service during World War II--predates ENIAC by two years.Colossus was bui lt during the Second World War at the Government Code and Cypher School at Bletc hley Park. Until very recently, much about the Colossus machine was shrouded in secrecy, largely because the code-breaking algorithms that were employed during World War II remained in use by the British security services until a short time ago. In addition, the United States has recently declassified a considerable vo lume of wartime documents relating to Colossus. Jack Copeland has brought togeth er memoirs of veterans of Bletchley Park--the top-secret headquarters of Britain 's secret service--and others who draw on the wealth of declassified information to illuminate the crucial role Colossus played during World War II. Included he re are pieces by the former WRENS who actually worked the machine, the scientist who pioneered the use of vacuum tubes in data processing, and leading authoriti es on code-breaking and computer science.A must read for anyone curious a bout code-breaking or World War II espionage, Colossus offers a fascinating insi der's account of the world first giant computer, the great great grandfather of the massive computers used today by the CIA and the National Security Agency.…
