Hi, I am programming an IRB 6400 M 97 S4C with a CAD / CAM pair to mill. I have the disadvantage that the size of the files is too large to accommodate in a 1.44mb memory. We have already split the program, and generated the so-called automatic programs.

We have discovered that the DSQC 330 motherboard has a SCSI port. Does anyone know if you can connect a SCSI hard drive? what type of partition and format should the disk have?

Thank you.
