    Thanks CNCBasis for the UC100 I purchased now having a way of connecting my Dave Gatton Cnc build to my New but Old Dell laptop is absolutely a blessing. My old desktop PC with parallel port failed I was in a state until I saw Dave show off his UC100 controller. Did not have one issue with software install worked from the start Thank You again and happy CNCing
