MultiplanMicrosoft's original spreadsheet program

For DOS:

ProgramDescription
Lotus 123 R1Most powerful. Some modern PC spreadsheets can load these old ones w/o any problems.
Lotus 123 R2Similar to R1. Could take advantage of the 8087 math coprocessor if present.
SuperCalcShipped with Borland Turbo Pascal. Under- powered. Operates like 123.

If you have trouble trying to load Lotus 123 Release 1 files into your modern spreadsheets (ex. MS Excel), first get a program called As-Easy-As, a shareware spreadsheet for IBM MS-DOS, load the R1 file, and resave in Lotus 123 Release 2 format. Most spreadsheets can read this file type.
