Vintage 1966 film excerpt from the IRS showing how an IBM System/360 mainframe system is used in their tax processing data center. About 4 mins long, color and narration.
Nice view of a 1960’s era data center and the System/360 master console. This excerpt focuses on the System/360.
The full version of this film is called “Right on the Button” and is also available on YouTube. (The model numbers of the equipment seem to have been taped over by the IRS film maker, but it is clearly the IBM 360, and its tape, disk and punch card peripherals)
