Components
Felker and Harris program TRADIC		Felker and Harris program TRADIC, AT&T Bell Laboratories announced the first fully transistorized computer, TRADIC. It contained nearly 800 transistors instead of vacuum tubes. Transistors — completely cold, highly efficient amplifying devices invented at Bell Labs — enabled the machine to operate on fewer than 100 watts, or one-twentieth the power required by comparable vacuum tube computers. In this photograph, J. H. Felker (left) gives instructions to the TRADIC computer by means of a plug-in unit while J. R. Harris places numbers into the machine by flipping simple switches. The computer occupied only 3 cubic feet.
