Vintage Synth Repair

Hello,

I am looking for the SCSI interface dedicated for TS10/TS12.
If someone could help me to find one of this kit or schematics/PCB to 
build one suitable for a TS12 ?

Let me know what could be find or do. Emu (owner of Ensoniq)seems not 
be able to locate this kit in the old Ensoniq Stock.

Maybe some Ensoniq user haves already build their own interface ??

Thansks for your help.

Gab.
