If keeping it to 8K has some merit: For a DW-only version one could
sacrifice the real floppy disk support, I think that would free up 365
bytes (the original DSKCON routine). Still not a lot and I don't know
how much WireBug would need. However it would be plenty for adding
some extra RAM hooks. Then a small wirebug server could be loaded into
RAM when needed and hooked up. The sacrificed floppy disk support
could also be loaded into RAM for the odd occasion.
