    On July 31, 1961 IBM introduced the Selectric or Model 72 typewriter. This machine constituted a radical departure from the conventional typewriter. It was designed as a high speed printer and was developed in part as a print out unit for IBM computers. The conventional type bars wers completely eliminated, and in their place a type element consisting of a removable type ball was substituted. The machine has proven to be a high quality typewriter giving excellent service and producing unusually uniform work. In September 1971 IBM introduced the Selectric II, an advanced model of their Selectric machine.
