  No, not quite.  The IOB can be anywhere in memory; you must pass the
address of the IOB in the Accumulator and Y register (I can't remember the
which byte goes in which register off hand though, sorry!).

  This stretches my memory a bit.  I think the entry point is $B7B5.  I
can't remember the complete format of the IOB.

  I probably shouldn't even bother posting this at all, but hey, I used to
know it all :-)
