This episode doesn't seem to be on anyone's favorite list but I really enjoyed it. The fear of machines is always a poignant topic and "The Ultimate Computer" speculates quite effectively about the application of technology without compassion. Asimov's Three Laws of Robotics arose out of similar concerns 26 years earlier. There's also a nice moment of foreshadowing for fans of the broader franchise. Spock comments to Bones that nothing in current computer technology can replace a ship's medical officer. Apparently, that shortcoming is sorted out in time for the Emergency Medical Hologram to be one of the central characters in the Star Trek: Voyager series.
Marshall also got loads of screen work. His most famous film role is as the title character in Blacula and its sequel. With his training, amazing speaking voice and impressive physical bearing, Marshall would undoubtedly have been a more prominent figure in a later era with more opportunities for African-American actors. He died in 2003 from complications due to Alzheimer's and diabetes.
