One of the most impressive computer systems ever was the vacuum tube based behemoth AN/FSQ-7, which was the heart of the ''Semi Automatic Ground Environment''. Machines of this type were children of the Cold War and had a tremendous effect in politics. They also generated a vast amount of spin-offs which still shape our world. This book focuses on the technological achievements and details of this marvelous machine and of its predecessor Whirlwind. The various developments, ranging from magnetic core memory to data transmission via telephone lines, are covered in detail with schematics, circuit descriptions and small programming examples. This book is a treasure trove for those interested in the technology of early digital computers and those interested in the impact these machines had and still have on our current computer systems.

Das Buch widmet sich AN/FSQ-7, einem der aussergewöhnlichsten und einflussreichsten Digitalrechner aller Zeiten, über den erst in den letzten Jahren (aufgrund von Geheimhaltungsvorschriften) detaillierte Informationen zugänglich wurden. Über einen Zeitraum von über 30 Jahren wurden in den USA 23 Rechenzentren auf Basis von jeweils zwei AN/FSQ-7 betrieben, die das Herz von SAGE, dem Semi Automatic Ground Environment bildeten, das für die Luftraumüberwachung der USA und (in Teilen) Kanada zuständig war.
Wounded Eagle
Wounded Eagle is a fictional account of actual events that took place during the US-USSR Cold War of the late 1970s. The title was a top secret code word used to describe situations which reduced or eliminated advance warning of an aircraft attack on the US Capital. Such warnings are provided based on a network of long range radar sensors deployed on or near the US coastline. Digital data from these sensors are combined and integrated into overall aircraft status pictures covering hundreds of miles over the ocean and an equal distance inland. The FAA and NORAD use these data jointly for real-time air route traffic control and early warning of intrusion or attack of the homeland. The Fort Lee AFS Direction Center in central Virginia provided data to NORAD to accomplish those functions for the Mid-Atlantic States including Washington, DC. At 0430 hours (EDT) on Monday, 8 August 1977, the NORAD Command Post within the Cheyenne Mountain Complex was notified that an air conditioning failure in the Fort Lee AFS Direction Center had caused severe damage to their air defense computers. The loss of all data from Fort Lee forced the NORAD Command Director to declare Wounded Eagle.
