I've held onto my PowerBook G4 1.6 GHz and PowerMac G5 Dual 1.8 Ghz for the sole purpose of running Morphos. BTW, I bought the PowerMac in 2008 for under A$500.00. After which I spent another A$500.00 for an LCD monitor, some extra RAM, extra hard disk, and USB Bluetooth. About a year ago I tried selling it on eBay for A$300.00 and nobody was interested. After hearing about Morphos on G5 I was glad nobody bought it.
I guess you are gladly running MorphOS on your PowerMac G5. How is it? Can you show some viideos?
