Microsoft Multiplan was an early 8-bit spreadsheet application for CP/M and MS-DOS with ports to numerous other platforms in the early 80s. Initially it competed against VisiCalc and later Lotus 1-2-3. A companion product, Microsoft Chart, provided graphing support. Multiplan was never ported to Windows, where it was replaced with Microsoft Excel. Excel also replaced Multiplan on the Macintosh platform.
Multiplan 1.x offered a relatively friendly menu driven interface, but had a very limited maximum spreadsheet size.
The MS-DOS version (at least 1.06) supports IBM PC, Zenith Z-100, TI Professional Computer, and Compaq.
Multiplan was ported to CP/M, Apple II, Macintosh, Xenix, Commodore 64, CTOS, TI-99/4A, and the TRS-80.
Wanted: some of those other ports, and manual scans. Version 1.00. Microsoft Multiplan 1.1 for DEC Rainbow.
