I am buying some used PowerBooks for resale here in Brazil. I would like to be able to do a fresh install of OSX 10.4 or 10.5 (depending upon model) on these systems, especially so I can have it in Portuguese for local buyers. My problem is finding a place to buy or d/l the proper OS for each model. Is here a site that lists all of this? I have one that gives a lot of useful information (http://www.everymac.com/systems/apple/powerbook_g4/index-powerbook-g4.html) but doesn't say specifically what build I need. Or is there a generic version that will work on a variety of PowerBooks? Macs are just really coming into their own here in Brazil and I want to do my bit to help that by offering people the best-equipped used models I can. Thanks for any tips.
