I believe the 8086, as originally designed and implemented, had a segmented address space with base and bounds registers in the style of the CDC 6600. This rudimentary but effective memory management approach was scrapped by Intel to make the 8086 part commensurate with the stepper reticle and semiconductor process of the time.
