TRADIC

TRADIC (English abbreviation for TR ansistorized A irborne DI gital C omputer) was the world's first computer based on transistors - and, because of its interference and failure safety and the higher speed of transistors compared to tubes, and last but not least because of its smaller size, it operated with it the triumph of transistor-based computers over the tube computers common at the time . TRADIC managed a million logical operations per second.

Developed by the Bell Research Laboratories for the United States Air Force , was completed in January 1954. It consisted of 10,358 Germanium - diodes and transistors 684 and had a power consumption of about 90 watts.

There are different details about the start of development of TRADIC and TX-0 . Some sources speak of 1953 for both computers. However, the TRADIC was probably the first computer based entirely on transistors.
