Comb bound. Condición: Near Fine. A scarce pamphlet documenting the United States Air Force's new IBM 707-III that it purchased from the Department of Agriculture in 1965. Likely printed in a very limited quantity as the introduction is signed by the department director, James R. DeCoster. 18 pp. Original stiff semi-glossy pages printed in black, with plastic front cover and orange comb binding. With two Officer Effectiveness Reports from 1969 laid in. Near Fine with light wear and light soiling.The 705-III was the last large-scale computer IBM designed using vacuum tube logic, which was made obsolete with the introduction of the transistorized 7000 series. Compared to it's predecessor, the 705-II, the 705-III had twice as much memory (80,000 characters) and four times the magnetic-tape character rate. The text describes the work of recording and processing weather data using magnetic tape drives and computers for the use by the armed services.
