I worked for the company that had the contract for the nav systems for Apollo. The IC's were too unreliable at that time to be used in such a critical situation. The on board nav system in the Apollo had only 8k of memory. It was most likely a magnetic core type of memory as they were the most reliable. As far as the electrical construction of the nav system is concerned, that was done using discrete components. There were few circuits boards and the components were soldered to buss lines. The entire assembly was then filled with potting and cured. There was then vibration testing, burn-in and thermal testing. At that time, this was the only type of electrical construction that could withstand the rigors of liftoff and space travel.
