We've got an old Acu-Rite Millpwr 3 3axis controlled Bridgeport knee mill. It still requires a floppy disk to load programs into it. It still functions but floppys are a pain in the....
I'd like to upgrade it if possible, does anyone have suggestions?

The servos work fine, I assume they are proprietary? or has someone successfully set up Mach3 or another NC controller with this type of controller?
