Emax

Hi, 
I just got an emaxHD, and am confused as to how to put sounds in it.
Do I have to use the floppy discs?
What is the connector in back for?
Can it adapt to SCSI, or??
I have a lot of Emu sounds on syqest and cd's
(some for esi, and some for EOS).
Is there any way to use these sounds in the emax?
Anyone want to trade any sounds??
Thanks,

Robert
