I just got an older computer (Just the tower) And I'm wondering how, or what I need in order to use both WITHOUT networking them, because I want to have a seperate OS on it, and be able to just switch to it on the fly. I understand that I can't transfer info between the 2 that way, but thats not what I want anyway. Just to use two seperate computers with my 1 monitor,mouse & keyboard.

So how do I do this?
