I converted a d&m 5 to run on Mach3. Just a little soldering and a couple of filtering caps, a parallel port connector and away ya go. No new drivers needed, just ran the existing drivers right off the parallel port.
If you are really seriously interested let me know. I did this last year for the local high school. They hadn't really gotten any use out of the machine due to the cryptic efforts to run the dos based program and they just let the machine set around until the old pc was obsolete and lost all the interface boards.
I can go in to the High School and trace out where I injected the step & direction signals to their original driver boards and let you know.
