- anyfoo 5y agoThough there were multiple solutions where the MMU sat outside the CPU, on the bus between 8086 and memory. That setup was common in general, but a bit less common for the 8086 specifically. Support wasn't perfect, often paging wasn't a thing, but isolation and protection in general worked somewhat reasonably.
