Hello Bryan,
I don’t run them but we have 4 Fadals where I work. All 15 plus years old. I will ask the guys that run them if they know what software you need and can get a copy. I take it you want to use a renishaw touch probe? After a little google searching looks to me if I find an original copy it’s going to be on a floppy disk. Tomorrow is a holiday so I am not too sure who will be there but I’ll ask around.
