Our old mill still uses it those floppy disk...those disk aren’t enough o memory storage...how do u guys do it if program is more than the disk limit at 1.44 mb? I see there’s a USB on the side and called my buddy but he said it doesn’t work or was never setup?? Why is it there and no use? Isn’t that the same on yours? My mill is a VMX 30 year 2006
