I need some feedback please, I have the privilege of buying one of these PowerBooks for approximately $200AUD, what has appealed me to it is the fact it comes with the original Apple carry case and some of the booklets. The battery no longer works, and doesn't come with the OS discs to do a restore, but the PowerBook still boots up when connected to a power source. Doing some quick research it seems as though these old PowerBooks hold much value anymore. What are people's opinions on these older devices? Thanks!
