Hollerith and System/360

Two distinctly different eras in computing are demonstrated by a pair of models. The first punched card tabulating machine (left foreground), invented in 1890 by Dr. Herman Hollerith, contrasts sharply with a new IBM System/360 Model 20 (right background) in 1964. Hollerith's machine was designed to automate tabulation of the 1890 U.S. Census -- at a speed of 10 cards a minute. The System/360 shown here could read up to 1,000 cards a minute while performing high-speed computations. (VV2143)
