Classic support???

I was looking for sim ant and found it but it is for mac os 9.1 or later. It also says it needs "classic support". My question is how can i get classic support on my mac (preferible for free). I do have to be really careful because this is a school computer with just about everything locked, some of which I have figured out how to bypass.

If this is not your computer, but rather a school's... then you will need to have them take a look at it and let them install Classic Support onto it.
Otherwise, you have no business trying to do it yourself.
