From Selected Computer Articles: March 1971, Compiled by the Department of Defense Computer Institute.
Some 70,000 computers were installed in the U.S. at the end of last year, according to this census taken June 30, 1969 by the Diebold Group, Inc. The graph at left projects the computer industry's growth to 1975. The graph on page 81 shows hardware component costs as a percentage of total systems cost. The Diebold Computer Census appears twice a year in the fortnightly ADP Newsletter published by Management Science Publishing, Inc., 430 Park Ave., New York 10022.
