	Does anyone know if two expansion slots of a MacIIcx are enough for the
	Ivory board and the memory expansion board? (I heard that in a MacIIx
	they take up three slots; I need the third and last slot of the IIcx for
	the video card).  Any other problems associated with configuring a
	MacIIcx as a MacIvory?
						Thanks in advance

    This is indeed a win.  Due to the locations of internal partitions in the Mac
    IIcx case, there is enough room to install the MacIvory board set in the third
    rightmost slot in the case, without covering up a slot.  This leaves both the
    other slots available for an expansion memory card

						     (both the NS 8MB card and
    the NS 16MB card set will fit)

I forgot one small point.  The NS 16MB card set is not exactly to Apple
standards.  An unmodified set will not allow the Mac IIcx cover to fit back on
properly.  The fix is minor: Nylon spacers are used to position the 8MB
daughter board above the 8MB main card.  One of the spacers along the top
edge of the card interferes with the card guide fingers molded into the top
cover.  Simply remove the offending spacer.

				 and a video card.  Obviously, this will have to
    be a standalone system as there is no slot for a network card.  Symbolics
    Engineering in Chatsworth brought a Mac IIcx up via normal procedures without
    any special problems.

    Note that MacIvory is not currently qualified for the Mac IIci until we
    complete support for Apple's 7.0 Mac software.
