Here I am. New used combo installed and does work. The computer does only start on Safe Mode. Actualli is Installed with macOs system is 10.4.11 I do only have original CD OS 10.2 With this OS 10.2 CD It doesn't boot on Hardware test. when I try to boot. I can read on screen : "Invalid memory access at SRR0 and SRR1" But trying the Hardware test (mac-boot + return) nothing happen. I've tried to install OS 10.2. Unfortunatly after restart for new installation. The screen is showing one black rectangle in middle. And nothing else happend. I that correct to try to install OS 10.2 instead of actual 10.4.11 ? Or better to try to install OS 10.5 or 10.6 ( I have CD of thoses). I'm stuck !!! please any advice.
