Multiplan was an early spreadsheet program, following VisiCalc, developed by
Microsoft. Introduced in 1982, initially for computers running CP/M, it was
ported to a number of other operating systems including MS-DOS and Xenix.
Versions were also available for the Commodore 64, Texas Instruments
TI-99/4A, Radio Shack Model II, Apple II and Burroughs B-20 series of
personal computers. Multiplan for the Apple Macintosh was Microsoft's first
GUI spreadsheet - the others were text-based. Multiplan for the Macintosh was
the most successful spreadsheet for the early Mac.
