The Z180 based FUZIX systems effectively have some minimal segmentation
rather than simple banking. You just need enough address space, and I
agree 512K of memory is tons for a well written OS. I don't think I've
ever managed to find a reason to use all the 512K of RAM on a Z180 based
FUZIX box !
The other advantage of ROM if all mapped is that with a bit of tweaking
you should be able to just insert the ROM banks into the segment map when
you do an execve so that split I/D ('small rather than tiny in DOS
speak') binaries can run with the code running directly from the ROM and
taking no RAM space at all.
