This an unflown but complete "Block I" Apollo Guidance Computer. Block I represented the initial design to meet NASA specifications for on-board guidance, navigation, and control needed for a Lunar Mission. It was replaced by a more advanced design, called "Block II," as the Apollo program matured. Block I computers were flown on three unmanned Apollo tests between August 1966 and April 1968.
Apollo Guidance Computers were designed by the MIT Instrumentation Laboratory and built by the Raytheon Corporation. Each used about 4,000 Integrated Circuits, which at that time represented a new and untested technology.
