Just to keep everything straight, the AGC that we restored is a totally different computer from the LVDC/LVDA that this board is from. The AGCs were on the Command Module and the Lunar Module that went to the Moon's surface, while the LVDC was onboard the Saturn V rocket.
The AGC was one of the very first computers to use integrated circuits, while the LVDC used hybrid modules. The LVDC used triple-redundant circuits with voting while the AGC was not redundant. The LVDC was a 26-bit serial computer, while the AGC was a 15-bit computer. The LVDC was built by IBM, while the AGC was built by MIT and Raytheon.
It's interesting that the two computers were different in so many ways.
