I have a 1.67ghz powerbook and a 1.5ghz powerbook, neither of these machines have the high res co. The display on the 1.67 is toast (I know it's the display for sure.) I am wondering if I can take the one from the 1.5 and put it onto the 1.67. My concern is that that 1.5 is a older than the 1.67 by about a year. That is to say the 1.5 is not from the 1.5/1.67 generation that was the last rev of powerbooks, rather the 1.33/1.5 generation. Any ideas? Thanks!
