Guides on emulating older applications

The Geometer's Sketchpad is an "automatic drawer" (a term used in geometry texts) which simulates compass and straight-edge constructions in a plane. However, this is a gross misrepresentation of this application's power. Opening the sample files you will discover it is possible to graph functions, create iterative processes, user parameter sliders (just like in Pacific Tech's Graphing Calculator), and a near Skewes' number of other capabilities.
