Code-named Electronic Paper, Multiplan was an early command line spreadsheet program developed by Microsoft and released in 1982. At the time, Multiplan was one of the most ported programs of all time, running on 50 different types of computers. Although not that successful on MS-DOS, Multiplan was popular on CP/M computers. Microsoft later abandoned Multiplan in 1985 when they started releasing Microsoft Excel, a graphical user interface spreadsheet program.
