Bernette 600
 

I just acquired a Bernette 600 embroidery machine. I know it uses .PES format. I have a Babylock Palette card writer. It loads the .PES designs on a card. The Bernette will not recognize it. Does anyone know the name of the writer box that will work on the Bernette? I have been Googling but can't fine this info. I know it is old so I am hoping to find a used one out there somewhere or on eBay.
Thank you
