You mean bank switching ? MMUs (Memory Mapping Units) are part of modern processsors last time I looked.
There was memory mapping in external hardware. As I recall, there were some boards that used the "LIM" (Lotus, Intel, Microsoft) standard for memory mapping boards in the XT systems. When the 286 came out, they were no longer necessary. I also used to work on Data General mini-computers. They could normally access 32 Kbytes,
That should have been 64 Kbytes or 32K words.
