I have good news and bad news.
MintPPC 9.3 installed on my iBook G4 1.42 GHz, 14" screen with bluetooth and scroll pad (scrolling works flawlessly). Install went smoothly, and had a hiccup once which required me to download a file again during the network installation. Wow, this is truly fast and an amazing OS!
*** side note*** Minitube is a wonderful addition for YouTube videos to play on my G4 PPC!
MintPPC 11 (debian mini net-install 20-Mar-2012) would not install following the instructions and I kept getting errors with the preconfig file not downloading. That led to the manual installation which kept giving me errors of the files not being available. I tried every server in the list, but I could not download the files
I gave up, and decided to go with 9.3... although I will be persistent with 11 until I figure it out!
Anyways, thank you and I will be donating!
