PPC Mac laptops used ADB as an internal protocol for many years after no Apple computer shipped with external ADB ports.

My recollection was that the transition to using USB as an internal protocol came slightly before the PPC->Intel transition, and that the first several generations of X86 Mac laptops used USB internally for trackpads and keyboards. You sure there were ever any using PS/2? Seems unlikely.
