Enclosed is version 3.5 of PLANET which supersed Planet 3.4.
PLANET is an application in which your Macintosh computes the coordinates of the planets visible to the naked eye , the sun, and the moon.
When a solar or lunar eclipse is possible you can also investigate the eclipse from any place on earth.
Version 3.4 added possibility to save the map and displayed sunrise and sunset times. The user could select decimal or sexagesimal representation from the default menu and also switch between azimuth origin north/south.
Version 3.5 computes directly the sunrise and sunset times by clicking on icons on the screen and produces a new data table. Sunset and sunrise may be calculated for the sun center in the horizon without refraction or the upper limb touching the horizon with refraction. Also decimal/sexagesimal switching is handled by clicking icons on the screen. A bug in the conversion decimal to sexagesimal routine is fixed. Balloon help is included under system 7.0. A more sophisticated About Planet dialog is added.
You should use a system 6.0.7 or later although it seems that 6.0.3 also works. The application has been tested on MacPlus, Classic, ClassicII, LC, LCII, IIcx, IIci, IIfx, and Quadra.
