I have a Dos program that lets me use Quadrature Encode on my mill and lathe that show the movement on my computer screen. but every time I run the program it exits the DOSBOX program. I had this DOS program working on an old dos computer but it finally gave out the computer that is. Can anyone help. I will attach a link to where I got the program. http://www.lindsayengraving.com/other_interests/dro.html
