Lotus Improv 1.0 for NeXTSTEP (m68K)
Released in 1991 by Lotus Development Corporation.
For m68K-based NeXT computers running NeXTSTEP

Improv is a spreadsheet program that attempted to re-imagine how one
would create and interact with spreadsheets.

It was first released in 1991 for NeXT computers, and for a time
became one of the NeXT's "Killer Apps".

Improv's features were useful to the financials market, and in 1993
Lotus released Improv 2.0 for Microsoft Windows. It was not marketed
as a direct replacement to Lotus 1-2-3, and 1-2-3 remained dominant
until both were overtaken by Microsoft Excel.

This archive contains three NeXT formatted (non-dos) 1.44mb floppy 
disks. Write them to a 3.5" floppy with a raw disk writer or mount 
them in an emulator.
