NoFinder

NoFinder is a freeware utility that was released for classic Mac OS in 1991, around the time of the release of System 7.

Description
NoFinder was written by Ricardo Batista and lists running processes and their memory usage under System 7, in which cooperative multitasking (formerly known by MultiFinder) was always enabled by default. Without the ability to switch to a single-tasking Finder in System 7 to Mac OS 9.2.2, NoFinder allows any process to be terminated or re-launched, including the Finder itself, to free up RAM usage.
