Welcome to the board.
Unfortunatly, I believe your friend is out of luck. There are both software and hardware conflicts to resolve.
According to Apple technical specifications [apple.com] :
Mac requirements
Macintosh computer with built-in FireWire port; Mac OS X v10.1.5 or later (Mac OS X 10.3 or later recommended)
First, a more recent OS is required. See this recent thread for more information about it:
OSX (Panther) on a revb imac? [webmasterworld.com] It's not as easy as it sounds.
Second, your friend will need a firewire card to connect the iPod to the iMac. This can be tricky, since some revisions of the iMac can lack the "mezzanine" slot to recieve the card. I heard of such cards but never shopped for them.
I believe Sonnet is sill making one wich also double as a processor upgrade, but this will more expensive then the iPod itself.
I am not sure the iPod will work with a simple firewire to USB adaptor.
I would start by phoning your local Mac shop to know if there is an inexpensive firewire card still available for the iMac. Keep the model # handy wile you talk for them to check if there is a mezzanine slot in the iMac.
I guess it's time to upgrade the computer...
