We had two of these onboard and if both were down we couldn&amp;#x27;t fire the missile system. I had 3 sailors dedicates solely to keeping these ancient machines running.&lt;p&gt;We got to diagnose some pretty cool bugs, like what happens when the card corresponding the the lowest significant bit of the least use register has an intermittent fault due to a bad mechanical connection.</text></comment>
