Q: Change Mac AFP Icon

Hello!

I share with my old PPC macs quite often (using an intel one), and I want to change the AFP device icon to the specific icon.

It usually just shows a cinema display, whereas for my iMac G4, I want it to show an iMac G4.

I have all the icons, I just have no idea how to change them.

I use my intel MacBook Pro OS X 10.8 to share with iMac G4 OS X 10.3 and iMac G3 OS X 10.3.

Thanks!
