You may have a particular definition of 'proper OS', but I was running multiuser/multitasking MP/M on 8085 and Z80s with bank switching quite effectively in the very late 70s. Later I switched to DRI's Concurrent on 8088/8086 with EEMS (eg AST RAMPage) and derivatives, such as DR-Multiuser-DOS (386/486). These and DRI's other range FlexOS were quite widely used in industry.
