I also need to see how the RAMWorks card's /RAM disk shows up differently than the standard /RAM disk. I have one, I just need to hook it up someday. For the quit code, I may restore it in a later version when I implement memory swapping (swapping the quit code would be easy, then). Re-launching VM02 may have to suffice for version 1.0.
