Recently bought a used 2010 vintage Chinese 1325 laser cutting machine. It was sold on the basis that the laser needed work, but on taking delivery I've found that it is also missing the controller. I need to know what controller this machine used originally. Hanging out the back is a cable with a 68-pin D-connector of the type typically used for external SCSI drives. This comprises two rows of 34 pins. I'd guess that it connected to a PCI/DSP card inside a dedicated PC.

The machine itself has no brand identification, except for the company that used to own it, Fritz Industries. They have morphed into another company since, and no-one remembers where it was bought except that it was acquired on a trip to China about 10 years ago. I have the packing list from when the machine was built. It is identified as SGE7100502 but there doesn't seem to be a company called SGE in China. It was signed off by Hong Qiang Su but again this clue led nowhere.

If anyone has seen one of these and knows who built it, please let me know. Bonus points if you can name the controller and software used. Thanks!
