I will take a look.  And to answer your questions, I believe the SWIM3 
is the driver for the last floppy drive on Power Mac and Power Mac G3
systems, and matching Mac Clones from that period.  The 7300-9600 macs
(and their matching clones) do have 2x CPU cards available for them. I 
actually have a 2x 180 604e card, and there are 2X G4 upgrade systems
as well for these machines.

Thanks all.
