Powerbook G4 uprgrade

[iMax]

If I've got an old powerbook G4 with just a DVD drive, how do I go about getting the upgrade to making it into a combo drive? Can I still do that?

Thanks

ONLY if you have a rev. b TiBook (550 or 667MHz). If you have a rev. a (400 or 500MHz) model then you cannot do it.

Of course, you will have to purchase the combo drive.
