I recently bought a macintosh powerbook 3400c from a friend. i have never used an apple comp before and i am entirely new at this. Anyway, i can't get past the boot-up password because i don't know the password and niether does my friend. It did come with install disks but when used it says that they are older version disks and that i need to use a version greater than 7.1. I have no idea what to do. my friend says that those are the disks that came with it, however, none of them work from boot-up. i have read numorous forums and have done numorous searches on google... everything says to try the command + s or simply the s button....this does not work where do i go from here?? help me please.
