		 <1>	  6/9/93	kc		first checked in
	   <LW7>	 4/29/93	fau		#1082085:  Added a bit to the Cyclone slotPRAM flags to indicate
									whether the "Boot on composite" should be NTSC or PAL.
	   <LW6>	 4/14/93	fau		Added the renumbered private control codes for Civic, plus some
									new structures.
	   <LW5>	 4/13/93	ejb		add the commas
	   <LW4>	 4/13/93	ejb		uncomment the new spFalgs bits for sound settings
	   <LW3>	  4/9/93	fau		Moved the spOpenComponent to 3 (from 6) and added the SpParams
									structure.
	   <LW2>	  4/5/93	fau		Changed the Cyclone-specific calls from the public area to the
									private area.  Added the definition of structures that were in
									the VDig .
