Greetings, and Welcome!
There is a fellow in Vancouver who distributes Centroid brand controls for Bridgeports and similar machines. The Centroid and a few others bolt up to the Bridgeport replacing the crank handles (I believe). He mailed me pictures of one that looked to have a full screen, MDI input and seemed a pretty adequate conversion.
To answer your question: YES they are sold but you will have to search them out. The one I came across was a Machine Tool Salesman.
Good luck in your search.
