I believe that Excel was originally designed for IBM and MSDOS.  It was
originally called Multiplan.  They needed to change the name in 85 as the
average person could not understand it.

I taught Lotus123, Supercalc, and Multiplan in the early 80's.  I beleve
Visicalc was the only spreadsheet originally designed for the mac.  If I am
in correct please correct me.

Thanks for mentioning Wikipeida

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.

Multiplan was the basis for Microsoft Excel which followed some years later
on both the Apple Macintosh (1985) and Microsoft Windows (1987).
