Treasure Island is based on the book by Robert Louis Stevenson. In the game, the player takes on the role of Jim Hawkins (unsurprisingly, since he is the protagonist of the book), and has to battle through hordes of pirates before a final showdown with Long John Silver.

The programming was done by Greg Duddle, and the music was rendered by David Whittaker . Also released was versions for Commodore 64 in 1984, and Commodore Plus/4 version 1985.
