Without a MMU this is impossible I think. Because you cannot have 
contiguous memory anymore, the MMU must make it look like contiguous.

Another possibility is overlays. Then you must split larger programs in
parts that fit in the memory, and if you jump to another part, another
overlay comes in. I think the new Turbo C for the PC only has
added automatical management of overlays.
