I have always read that the Apollo guidance computer
was no more powerful than a typical calculator.
Here is an interesting few links about the AGC in the Command and

some of the more interesting details to me

It mentions that a full minute of guidance inputs were ignored on descent
to the moon because of the '1201' and '1202' alarm story
