This is an unflown example of the Electronic Communications Inc. computer that was installed on the Saturn V Instrument Unit (IU), and that controlled the gimbals of the rocket motors. It was an analog computer, and was separate from the Launch Vehicle Digital Comptuer, which performed the primary guidance and navigation functions.
This specimen may have been intended for the Saturn V #513, which was a Skylab mission. However it was removed from the IU after initial installation, for reasons unknown.
The U.S. Space and Rocket Center donated this to the Smithsonian in 2008.
