Tautology

Professor Marius writes in his computer diary that he has been posted to a station close to the space lanes and believes he will be bored there. He acquires an old computer from his niece's fiancé. Strangely, although it is from the 20th century, its technology is far in advance of that time. However, due to shuttle weight restrictions he is forced to not only have it scrapped, but also to leave behind his dog Toby. He keeps the computer's motherboard and Toby's dog tag as mementos. At the station, he befriends an electronic specialist who helps him construct a new computer based on the motherboard and sketches Marius drew. The professor plans to name it after the old computer: K9.
