Thanks, again, for your input, gents. Much appreciated.
The supplier of my system "provided" me with what they claimed was a legitimate copy of Mach3. When I unzipped their file, my anti-virus went off like my dog when she sees the mailman. It had the ******************66 build version, and so I figured it must be pirated. But, while it may be pirated, based on what Craig was saying, it may be that they have "tailored" their build to their board. I don't REALLY want to try it, but perhaps..........we'll see what tomorrow brings.
How does one determine legal copy, or not, besides looking for the license code?
