My first thought of a movie for this article was Saturn 3 with Kirk Douglas.
https://www.imdb.com/title/tt0079285/
In the future, Earth is overcrowded and the population relies on distant bases to be fed. In the Saturn 3 station, Major Adam (Kirk Douglas) and the scientist Alex (Farrah Fawcett), who is also his lover and has never been on Earth, have been researching hydroponics for three years in the base alone with their dog Sally.
Meanwhile, the psychotic Captain Benson (Harvey Keitel) fails the mental test required to travel to Saturn 3 and kills his replacement, Captain James, taking his place in the mission of assembling and programming the Demi-God series robot Hector to replace one of the scientists in Saturn 3.
On the arrival, the mentally disturbed Captain Benson becomes sexually obsessed for Alex. Then he uses an interface to link his brain to program Hector, but incapable to control his emotions, he transfers his homicidal tendency and insanity to Hector. Now Major Adam and Alex are trapped in the station with a dangerous psychopath robot.
It has been a loooong time since I saw that one. I also thought of the second season of the Buck Rogers TV series. There was a robot (Kryton) that had an organic brain. Also, the titular starship in Star Trek: Voyager had organic “packs” that were part of the computer system
Ooops, the robot that I mentioned in the Buch Rogers TV was actually named “Crichton.”
