Question: What had four separate designs and replaced The PowerBook and iBook lines?
Sentence (from "Old World ROM"): In common use, the "Old World" designation usually applies to the early generations of PCI-based "beige" Power Macs (and sometimes the very first NuBus-equipped models), but not the older Motorola 68000-based Macs; however, the Toolbox runs the same way on all three types of machines.
Relevant evidence: No
