The Commodore Plus/4 was a home computer released by Commodore International in 1984. The "Plus/4" name refers to the four-application ROM resident office suite (word processor, spreadsheet, database, and graphing); it was billed as "the productivity computer with software built-in". It had some success in Europe. A total flop in the United States, it was derided as the "Minus/60"—a joke on the difference between the Plus/4 and the dominant Commodore 64.
