Wasn't that the same alarm that was randomly thrown at the astronaughts in training and they made the wrong choice then and learned to make the right choice on the moon?

I will look up the story in Kranz's autobiography when I get home tonight.

I do believe it was. The Simsups threw a 1201 alarm at them, and the controllers got confused, and Kranz called an abort. Afterwards, they told him, "It wasn't an abort, you should have continued the landing...I thought you guys had it, but then you went off the rails and called for an abort...You violated the fundamental rule of Mission Control: You must have two cues before aborting. You called for an abort with only one! " As a result, one of the controllers went more into depth on program alarm codes, and they put a rule in dealing with which alarm codes would be grounds for an abort. Neither 1201 nor 1202 were on that list. They saw both those alarm codes during Eagle's descent, and were able to say, "We're Go on this alarm...we're still Go, same type, it's a Go." And the rest was history.
