Your contribution greatly helps! Thank you! ~ CHAP. -- This film provides a good depiction of a 1957-1960's era data processing installation at a U.S. Air Base. - Titled: "Logistic Support Management in Advanced Weapons." Although the letters “IBM” were apparently taped over by the original film producers, the equipment is clearly an early IBM mainframe, almost certainly a model 705 EDPM with its accompanying peripheral devices. The IBM 705 was introduced in 1954 and installed starting in 1956. It was a large vacuum tube based computer -- one of the most powerful data processing systems available at during the late 1950's. This 20 minute film has good quality, color and sound, lightened up slightly from the original to improve the detail of the computer equipment. Computer footage starts at 4 minutes into the film.
