Circuit Overview:
     A 21 voice digital ROM sample based machine with some nice performance interface features. VFX-SD much improved with non-dos floppy and other improvements.

Service Tips:
      Always verify power supply voltages if problem looks like it could remotely be power supply related. Some people had problems with scsi drive interfacing on the later ones that could do that as I recall. Haven't heard other issues on these. Anyone?

Syntaur has many parts for Ensoniq specifically. Let me know if you need a specific part from my listings in the parts section that you don't find elsewhere or whatever.
