NuCalc, also known as Graphing Calculator, is a computer software tool made by the company Pacific Tech. The tool can perform many graphing calculator functions. It can graph inequalities and vector fields, as well as functions in two, three, or four dimensions. It supports several different coordinate systems, and can solve equations. It is available for OS X (under the name Graphing Calculator) and Microsoft Windows. The Graphing Calculator 1.0 software was bundled for free on all Power Macintosh computers since its introduction in 1994. Having shipped on more than 20 million machines, it is the most familiar version of the program. This version of Graphing Calculator was secretly developed at Apple by Ron Avitzur, an abandoned contractor who felt obligated to complete the project, and their friend and colleague Greg Robbins. They also made a version for older 680x0 Macintosh computers called NuCalc 1.0. In 2005, This American Life featured Avitzur's story in episode 284, Should I Stay or Should I go? More information...
