We have a D&M CNC Mill in our Tech.Ed. Lab.The computer went out we found another computer. I discovered that my 31/2" floppy disc will no longer work.I need a copy of the software to get the mill up and running.The software is: master install version 2.01,level 3 version 3.25, level 2 version 2.40. This has been a great module for the students and I would like to keep it going. Thanks,Gary.Matthews@stephenscountyschools.org
