You can have a > look to Alan's FUZZIX project presentation, where the banked memory is > a must-have : https://github.com/EtchedPixels/FUZIX 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.
