History
EarthPlot 1.0 was created and released into the public domain by Peirce. Richard Heurtley originally wrote the plotting functions in.

EarthPlot 2.0 was released in December 1985 with improvements by Marsh Gosnell. Its About and Quit menu functions do not work correctly under Macintosh System 6 and later.

EarthPlot 3.0 was released in 1987 by The Black Swamp Software Company. It fixed compatibility with System 6, added support for color, and moved the plotting area into an "EarthView" window which could be resized to accommodate larger monitors. EarthPlot 3.0.1 is the last known version. The Think C source code is available, but is not complete.
