As a child born in the 80's, I thought I would celebrate this decade by designing some caches based on movies and songs ... you've guessed it that were released in the 1980's.
To find this cache all you have to do is collect the numbers written in the 1980's series caches - there are 10 in total. Each of these caches represents something that was released in each year. All you have to do is work out when each thing was released and put them in the correct order from 1980 to 1989 then hey presto the numbers from the caches will form the co-ordinates.
This final cache is based off a famous 1980's video game.
