No ADB or Serial Ports
The USB ports take the place of the ADB and serial I/O ports found on earlier Macintosh computers. Software shims have been implemented in the system software to allow existing applications that use ADB devices to work with USB devices.
The Power Mac G4 computer uses a USB keyboard and mouse similar to the USB keyboard and mouse introduced with the iMac computer.
USB game controllers are supported by the InputSprocket component of the Apple Games Sprockets software architecture. InputSprocket software and information about the InputSprocket APIs can be found at
