The demonstration you are watching on the cathode ray tube is called Spacewar. At first look, Spacewar is a fascinating space-age game, in which two players maneuver rocket-armed spaceships in the near weightlessness of space until one is in position to fire the winning shot. The code is run from a binary paper tape image (RIM) labeled  spaceWar_SA-5.bin 2  . This has been proven to be identical to loading the two paper tapes  spacewar2B_2apr62.bin  and  stars.bin , both to be found at bitsavers.org.
