One other thing I'm trying to understand is the addresses themselves. As it stands right now I have:
Heavily modified MP-M covering $A000-BFFF DRC 16k covering $0000-3FFF DRC 16k covering $4000-7FFF Again I don't know what I'm talking about here -- but the DRC table says you could config one more for $C000-FFFF. Is that worth doing? I do have this last 4K MP-M board here. It is slightly modified with a couple of cut/changed traces. Right now it is, at least by the documentation, set as board #5, which according to this: http://www.swtpc.com/mholley/MP_M/MP_M_AssemblyInstructions.pdf is 5000-5FFF? I'm not sure how these addresses correspond to what's in the DRC guide. Could this board cover $C000 somehow? Brad
