TRADIC's new version, the first transistorized electronic brain for automatic bombing and navigation, gets a check at Morristown, N.J., by some of the Bell Telephone Laboratories engineers who designed and built the electronic system.
The system resulted from one of the earliest applications of transistors for the U.S. Air Force to airborne didital computers. From this program came the first all transistor computer, TRADIC, announced by Bell Telephone Laboratories in 1955.
The basic principles of TRADIC were applied to a new computer which developed into the new TRADIC system, the first all-transistor bombing and navigation computer, the system includes a partially transistorized radar, incoding and decoding devices, decimal display devices, the plane's instruments, and navigation equioment.
The new TRADIC is the fastest airborne digital computer system availabe. It can perform 62,500 basic computations per second and processes flight and other data fed it by the operator and the aircraft instruments. The system makes available to the Air Force a completely new apporach to achieving the accuracy, releability and ease of operation required of modern, airborne weapons systems.
