  As noted in my response to Darren just now, I latched SCS~ and then
  asserted SLENB in a test to see if I could get my device to slide
  everything off the bus (I understand the sIDE is there, but I was
  assuming it would not be, since its slot was not selected.)

  I do see that Glenside is fully decoded.  That is unfortunate, as that
  means that the MPI available SCS~ space is effectively been halved in a
  system that uses an IDE controller.  Only $ff4x is available in the
  SCS~ space.

  And, it decodes the entire $ff5x space (it appears to repeat the latch
  byte for 8 bytes, as does sIDE to emulate it.)

  Are the registers for the Gen3 Virtual ROM pack in a specific spot (so
  I don't step on those address if I move them?)

  Jim
