Why would the age of a machine have anything to do with it? Seems to me that any machine with G96 (CSS) also has a code for maximum spindle speed. That's a "G50" with a "Sxxx" command on most any Fanuc control. I wouldn't go into CSS mode without a G50Sxxx command, no matter if the machine was 30 years old or brand new!
