Spock is impressed with the M-5 multitronic unit

On stardate 4729.4, the Federation starship USS Enterprise NCC-1701 is summoned to a space station without explanation. Commodore Wesley, commanding a group of starships from the USS Lexington, explains that the Enterprise will be a test vessel for a revolutionary tactical and control computer called the "M-5 Multitronic System", designed by the brilliant Dr. Richard Daystrom (who had also invented the TOS era computer systems after developing duotronics when he was 24 years old). The M-5 will handle all ship functions without human assistance. While Captain Kirk and Chief Medical Officer Dr. McCoy are unhappy about the test, Science Officer Spock is impressed with M-5.
