where can I download itunes 6?

I have an old iMac PowerPC G5 that I just fixed up with new disk and memory. I use it for sharing family photos and the like and for my syncing witn my AppleTV (gen 1). I need to get to iTunes 6 or 7 I think to sync with Apple TV, but I can't find the downloads on the support site. Could anyone tell me where I might find older versions of iTunes, iPhoto, etc?

Thanks
