Casio CZ/ VZ/ FZ - Pro Series

Hi all! I just got today a never used (looks like never used, inside-
out, but the guy told me the floppy doesn't work) sampler and need 
some info on that. It has a SCSI-looking interface on the back and 
it says external port. I have an Ensoniq EPS 16+, Akai S3000i, and a 
Syntec 2 CD 2 HD SCSI interface (rack). I also have a Phillips 
external SCSI cd device drive, and a SCSI hard disk in an Apple 
case. 
Q:
1. Can I connect anything of that to this sampler to make it store 
samples/synth patches?
2. I read it has additive sythesis and waveforms? Can I use those 
without the floppy? 
3. OS load: floppy, rom, ram or SCSI? (I'm not sure I want to plug 
it in, until I connect a right floppy or the non-working one (now 
unplugged) - just paranoid like that, since I almost burned the EPS 
when I connected the SCSI cable to the flash rom interface.... it 
looked the same, the cables fit... but..... :))

Thanks, Josh
