Overton had once worked at N.A.P., and was then working at Milton Bradley with Harris when he was called to lead the new N.A.P. design group, and he brought Harris along.
After N.A.P. stopped working with video games in the middle 80's, Harris and most of his colleagues worked on a self-contained work processor called The VideoWriter. He worked for N.A.P. until 1988, and after that, he went to work on optical recognition systems.
As of 2001, he worked with embedded programming for digital TV.
