The URL showed the backside of a 17" iMac. The Mickey Mouse Power Plug is for 90-270 volts AC with similarly wide frequency range. As others have mentioned is apparently the same as the AC power cord for the power supply yo-yo used on titanium Powerbooks. The iPod uses 6 conductor Firewire for both power and data. The iPod power supply AC adapter also has a Firewire connector. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
