Lotus 1-2-3 1.x (DOS)

Lotus 1-2-3 was an early spreadsheet application available for MS-DOS. It became extremely popular in the late 1980s, displacing the former leader VisiCalc. Lotus had difficulties adapting 1-2-3 to the Windows environment, and was overtaken by Microsoft Excel. Spreadsheet functionality was also included in Lotus Symphony. Later versions were included in Lotus SmartSuite.

Wanted: Additional Ports of Lotus 1-2-3, and Lotus 1-2-3 97 Edition (first 32-bit Windows version)
