Year 1955: 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. The computer occupied only 3 cubic feet.

"Home Computer" of 2004 from Rand in 1950s. I think they missed the scale of the equipment and power a little with this prediction.
