Hi, As I understand it, the 36mb, 40mb and the 48mb RAM modules for the 2300c cannot be used in the lesser Duos. What exactly happens when one of those larger modules is used on a lesser Powerbook? I have an unidentified RAM module that is a double-decker, BUT it only registers as 14mb (making 18mb total) in my 230 and 280c. Help? Thanks! Craig W.!
