Description

Black and white image of hands holding a TRADIC transistor. Verso Bell Labs label: "Subject: COMPUTERS General - TRADIC. Number: B654/0-7. Source: Release, March 14, 1955. Date Taken: 1955. Background Information: One of nearly 800 transistors used in Bell Laboratories' new airborne digital computer is inserted into a "memory" package. Memory packages used in production models of the computer will be about one-half the size of the laboratory model displayed in the picture. TRADIC, the new electronic "brain," overcomes jet aircraft's electronic problems of vacuum tube failure and heat through the use of long-lasting, completely cold transistors instead of vacuum tubes. Original: (B/W box checked. Negative: (120 box checked)." Verso numbers 6.1.4-4 (crossed out), #1212, 25.4-12 (crossed out), B654/0-7, B654-7.
