Re: [CAD_CAM_EDM_DRO] Re: Conversational programming in Perl for EMC

Guys,

I am all for porting this puppy over to my fav. OS LINUX. However, I am
concerned that if people have to purchase new controllers, expensive ones at
that, we may slow down the "market" acceptance of this product.

What about designing a parallel port controller that has an external
interrupt to clock activities. Greg Nuspel and Hans Weidermeyer have
designed such controllers. They could be made easily by hobbyists, Dan
Maunch etc.
