Original NASA Apollo Saturn V Moon Computer Core Memory

This is a genuine NASA Apollo Saturn V Launch Vehicle Instrument Unit (I.U.) Digital Guidance Computer
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 there 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.
The dimensions are about 5.25 inches long by 3 inches wide by 0.25 inches thick.
I great part of Apollo Moon Shot history the had an original acquisition cost in the thousands of dollars.
Note: These pictures are of a nearly identical unit to the one you will receive.
