The Intel 8086 processor does not support virtual memory. Nevertheless, some companies previously sold systems that contained an unmodified 8086 CPU and do paging. Make an educated guess as to how they did it. (Hint: think about the logical location of the MMU).
The purpose of the MMU is to translate memory references caused by machine code instructions from virtual addresses to real addresses. Hence, the logical location of the MMU is between the CPU and the memory. In particular, this means that the MMU does not need to be part of the CPU - it can simply sit on the system bus between the CPU and memory, and provide translation facilities.
