Multitronics were an advanced computer system, an evolution of the older duotronic system. A multitronic computer could theoretically be advanced enough to run an entire starship by itself. Multitronics, though very advanced, were a dead-end for most civilizations in the Milky Way, because it was nearly impossible to create a stable operating system for a multitronic system. In the United Federation of Planets, Doctor Richard Daystrom attempted to solve this problem by using his own memory engrams as a basis for the M-5 computer, but the resultant system was revealed to be insane after it was tested on the USS Enterprise (NCC-1701) in 2267. The Federation ultimately abandoned multitronics in favor of isolinear technology. (TOS episode: "The Ultimate Computer", SCE eBook: The Future Begins)
