re iisi question the si has a single expansion slot that can be either pds or nubus but not both together the card lies parallel to and above the motherboard hd and requires an adaptor slot to do this there are nubus and pds adaptort cards thus what kind of slots you have depends on what kind of adapter card you have with the exception of the radius rocket all nubus cards i know of work in the si pds slots and thus cards are mac specific thus not all pds cards work in all macs from planet bmug the firstclass bbs of bmug the message contained in this posting does not in any way reflect bmug s official views
