What is PPC Mac OS X 10.5 Leopard Beta 9A241?

9A241 is an early Mac OS X 10.5 Leopard beta release and one of the only builds that still supported Classic Environment (Mac OS 9.2.2 in OSX) before Apple finally prevented official builds from running it.

Mac OS X 10.5 beta (9A241) is also said to work on higher end G3 models, which Apple also prevented in official builds.  Although it's going to be extremely slow, if you still choose to go that route, know that there is a thread that explains how to achieve it: https://www.insanelymac.com/forum/topic/25942-105-on-a-g3/
