David, I believe the latest release of MapMaker will do what you want using the Kurta or other supported digitizing tablets. It might take a two or three step process to get a text file of screen coordinates, but the newest MapMaker is designed to take input from the digitizing tablets as a series of points connected by line segments (it only stores the vertices). You can then scale your input to either pure screen coordinates or latitude/longitude pairs, and dump the boundary file as a text file of point pairs. You might then have to edit the file to get it in the format your want, but the points will be there. Please email me if you need/want more information. I have just started working with MapMaker and a Kurta 12x17 tablet.
