Background Information: "TRADIC, a new digital computer developed at Bell Telephone Laboratories, contains nearly 800 transistors instead of vacuum tuves. Transistors, completely cold, highly efficient amplifying devices invented at Bell Labs, enable the machine to operate on less than 100 watts - one-twentieth of the power needed by comparable vacuum tube computers. J.H. Felker (left) gives instructins to the computer by means of a plug-in unit while J.R. Harris, (right) places numbers into the machine by flipping simple switches. When design work has been completed, the computer will probably occupy less than three cubic feet of the critical space in modern military aircraft. Persons shown: H.H. Felker & J.R. Harris"
