The MOS 6509 has bank switching hardware built into the CPU, instead of being on an external MMU chip such as the MOS 8722.
What makes the CBM-II's 6509 fundamentally different from the C128's 8502+8722 combo? And what makes either fundamentally different from the segmentation scheme of the 8086/8088?
