Data Desk is a tool for Exploratory Data Analysis (EDA). First released in 1986, it is one of the oldest Macintosh programs still actively developed and sold. It is now cross platform with support for OS X and Windows.

I've received permission to compile a version for Macintosh 680x0 and make it freeware. Data Desk for Macintosh 680x0 is available from my Gryphel Project web site.
