The Remington Rand 409, a punched card calculator which was programmed with a plugboard, was designed in 1949.[citation needed] It was sold in two models: the UNIVAC 60 (1952) and the UNIVAC 120 (1953). The model number referred to the number of decimal digits it could read from each punched card.[1]
The machine was designed in "The Barn", at 33 Highland Ave. in Rowayton, Connecticut, a building that currently houses the Rowayton Public Library and Community Center.
These machines were discontinued when the UNIVAC 1004 was introduced in 1962. About 1000 total had been produced by 1961.
