Akai S1000 / S1100 samplers

I recently bought a used Apple 600e and I hooked it up to the 
S1000PB, but it does not seem to recognize it. What do I have to do, 
I tried the SCSI soft key but it doesn't seem to do anything, bad 
SCSI card?!?!?! Help please. I have only one CD rom that came with 
the PB The guy who sold it says it has the 4.40 OS and some samples 
on it but I can't seem to get it to work.
