Ok so I ham buying my sister a g3 300 mhz b/w model for x mas anf putting panthr on it. my question is the g3 is coming with os 9 on it and i have a g5 will the g5 discs install on the g3 ? The g3 has only a regular cd drive and panther is on dvds so i saw this external player / burner would this work with upgrading the os http://www.walmart.com/catalog/product.gsp?product_id=2620263 ? The reason i am asking is because i am buying a family pack of tiger and instead of spending $130 on panther i could buy this cd burner for less . Can i do it?
