This is one of the earliest known Mac OS X 10.5 Leopard builds for
PowerPC
This is actually compatible with G3 systems as long as you modify the
supported machines plist file

Special thanks to xXkingtommy123Xx for providing me the rar file!

This is how to get it working on G3's and I am certain it should work
just fine even if this is meant for another build (Based on some
comments indicating for 9A321 which I am on a hunt for now):

EDIT: 6/9/20 : I am going to more than likely upload a pre-installed
copy of this Leopard build for people who want to install it easily
without installing it via the disc image etc etc. This should also
help G3 users out and I'm also going to upload a version of the
installer where it doesn't require the check so if anyone wants to
install it on their own on a G3

EDIT: 6/10/20: I could not get PearPC or my iMac G4 to boot the
installer, I tried the traditional USB install method for the iMac
which normally would work but didn't, I have yet to make this attempt
with the iBook G4 and G3 I have lying around, however I am installing
it as a dual boot with Tiger & Leopard on said iMac G4 by using the
"OSInstall" package file

To do this, go to the install media, then "System" -> "Installation"
-> "Packages" -> OSInstall.mpkg, open that and it will open the macOS
X installer
