Information Processing Techniques Office
The Information Processing Techniques Office (IPTO), originally Command and Control Research, was part of the Defense Advanced Research Projects Agency of the United States Department of Defense. == Origin == According to an ARPA-sponsored history of the organization, IPTO grew from a distinctly unpromising beginning: the Air Force had a large, expensive computer (AN/FSQ 321A) which was intended as a backup for the SAGE air defense program, but no longer needed; and it also had too few required tasks to maintain the desired staffing level at its main software contractor, the System Development Corporation (SDC).
