- You will get problems as far as the central parts, the custom
- chips, are concerned, because these can not be looked at in single
- parts, they only work together. For example, the DMA base/counter
- registers are located somewhere in the MMU, because the DMA does not
- have the necessary address lines, and the same is true for some
- other parts of the DMA/Video/RAM subsystem.
