I like to think of myself as fairly compentent computer user, but when it comes to hardware and networking, I am lost. So here is what I want to do. I have a 12" PB G4 (OS 10.2), PB G3 266 (Wallstreet), and a Compaq P3 600 (Win XP). All have network cards. I primarly want to set this up for file sharing. (I develop databases on the side and like to check things out on different platforms/versions). Eventually I would like to add a network printer, but that is down the road a bit. There is no internet connection involved. What hardware/software would be involved in doing this? What mistakes or troubles can you enlighten me about before I make them? Thanks!
