High-speed movement of securities orders on the Midwest Stock Exchange is handled by this new computerized communications device in the Chicago officer of the Exchange June 16, 1971. While R. Thomas Rehwald, senior Vice-President and treasurer of the Midwest Stock Exchange Serviced Corp., watches, Arois Ruehl types information into the machine for storage and transmission. The system, Signet 80, handles paperwork more than 20 times faster than any previous system. (Photo by Charles Knoblock/AP Photo)
