Megamax C was a C compiler for the Mac. It featured a cobbled together
IDE by bundling a text editor called FastEddie 3.0 which included
options under the File menu to run the Megamax compiler and linker.

Megamax C would quickly disappear when Lightspeed-C became the de
facto standard in the mid-1980s.
