The Graphing Calculator 1.0 software has been bundled for free on all Power Macintosh
computers since its introduction in 1994. This means that it was shipped on more than 20 million machines, and is the most familiar version of the program. This version of Graphing Calculator was secretly developed at Apple by an abandoned contractor who felt obliged to the project. They also made a version for older 680x0
Macintosh computers called NuCalc 1.0.
Later models of Power Macintosh computers included newer versions of the Graphing Calculator program. Now, versions are available for free download for Mac OS 9, Mac OS X 10.3 and Mac OS X 10.4. However, these versions may lack some of the features of the original version 1.0 program and may include promotion for the more advanced, commercial version of the software. The latest commercial version is Graphing Calculator 3. There is also a commercial version for Windows (again renamed NuCalc). There is no free version for Windows.
