This is a genuine NASA Apollo Saturn V Launch Vehicle Instrument Unit (I.U.) Digital Guidance Computer Core Memory Diode Assembly.This unit contains several hundred diodes used as part of the high speed core switching system.I personally acquired this artifact from a Charles H Bell auction. He purchased it at a Kennedy Space Center auction back in the late 1970's.A duplicate version of this board flew on every Saturn Rocket that carried the Apollo Astronauts to the moon and was a critical part of the Saturn Vehicle Guidance Navigation and Control System.This Artifact was used in the Saturn Instrument Unit (I.U.) Guidance and control Computer. The I.U. was part of the Saturn V third stage and was situated just below the Lunar Module. It was designed to control the Saturn V Rocket from liftoff through to Trans-Lunar injection. Since all flown parts of the Saturn V third stage are either destroyed or floating in space t are no flown examples on earth. This is a spare from the Saturn Flight Computer. It was a backup in case an on board computer failed..This Core Memory was specifically designed by IBM for the Apollo Saturn V Moon Vehicle. .IBM was the prime contractor for the Apollo Saturn V I.U. They designed and built the Guidance, Navigation and Control Computer for Saturn Apollo.PART NUMBER 611 03 28SERIAL NUMBER 726The dimensions read more
