Thank you LCGuy for the explecite step by step instructions for me. I have only very recently mastered how to install batteries in my LC520, Performa6360, 8500, QS G4 and also memory sticks and a PCI audiophile card in the QS G4. As I get into my macs i manage not to loose or forget to install those mini machine screws. Although any i forgot to install i simple place them in a plastic bag and tape them to the mac they should go back into waiting for the next time i have to go inside unless there;s a lot of noise which means to me that i should get back in and put those screws in.
Now my task is to find card you noted i should buy/install. At this time not too sure how hard they are too find.
I hope i can come back to this post when i get the card and no doubt will be asking for more help.
