Centroid Controller problem

I have a Millport mill with a centroid M60 controller. Uses the CNC7 software. It is a 1994 386 DOS based system.
I think the M4,M10,M20,M40,M50,M60 use similar if not the same software, differences being capability of interfacing to a PLC for motor/pump.. control. My hard drive has died and I am looking for the files to reload on new hard drive. Do any of the PM members have copies of old Centroid DOS files?
