Patches and discussion for Ensoniq VFX family

Hi. I just bought the Ensoniq VFX-SD synthsizer. I got it used 
(obviously) with nothing but the keyboard itself. No OS disk, no 
sound disks... nothing. I can't run the sequencer at all, and I was 
wondering if my only choice was to buy the OS disk off the internet. 
I've found the OS files for free download, but I can't put them on a 
disk and load them into the keyboard that way. Am I just putting 
these files on the disk wrong, or do I have to use a MIDI-in cable 
from my pc to the synth? I figured you could load sounds into the 
keyboard from the pc, but I wasn't sure about the OS itself. 
Hopefully I make sense here... I'm kinda new to synthesizer 
ownership. Especially one so old and complex. Anyway, thanks for 
reading, and please help.
