Re: [CAD_CAM_EDM_DRO] Re: Interface. Gauging interest.

I read the "CNC Explosion" article on the camtronics-cnc site. It says:

"Concurrently, Art Fenerty and Karl Carken obtained the free source code and
developed their interpretations of the EMC program fixing many of the
problems and making it run much faster and better. Art ( www.artofcnc.ca)
solved the problem with windows timing issues with the parallel port by
using a internal timer found on most motherboards. This smooth out the pulse
stream and now made using windows 95,98 and XP a viable alternative. His
latest version called Mach2( cost $150) is and awesome program that is
divided into to portions."

It sounds like Mach is derived from EMC. I have often wondered if it was
because it sure looks like EMC. Since EMC is released under GPL (open
source), doesn't that require releasing the source code for Mach?
