I want to use an old imac (slot) as an internet device for my daughter. What I have has no software on it at all. Not even an OS. I have discs w/ 9.0.4, 9.1 and 9.2 updates as well as OSX. Nothing works. Holding C key down on start-up doesn't boot 9.0.4 disc. Beyond that I am clueless. A little help please!!!!!!
