Ok, so after asking opinions about which trackball powerbook to get, I go out and get a 540. Now I have this Belgian powerbook and I need a power supply. I'm thinking that I'd like to find another model powerbook with that comes with an adapter that can work with the 540 as well, so my question is, which powerbooks share the same power supply as the 540? All the 500 series? Any of the 100 series, or duos?

Thanks,

Nathan
