'Galactica Discovers Earth' (Part 1) by Glen A. Larson

After thirty years of searching for the lost colony of Earth, the Battlestar Galactica and its Colonial fleet finally approaches their objective. However, the Earth is not the technologically advanced world that they hoped to find - this is Earth in the year 1980, a time when its technology is no match for the pursuing Cylons. Commander Adama and his advisor, fourteen-year-old genius Doctor Zee, are forced to decide on a radical course of action: they take the fleet away from Earth and then send Lieutenant Troy and Lieutenant Dillon down to the planet on a secret mission to speed up the Earth’s development…
