Raaka-Tu is one of 3 machine language text adventure games that Radio Shack originally brought out on the TRS-80 Model I/III series, and then converted to the Coco (the others being Bedlam and Pyramid 2000). This was probably the most straightforward of the three... there is no randomly shifting rooms, or multiple endings as in the other two. In this game, you have to try and steal treasures from a temple in the middle of the jungle. This was the first adventure game I ever bought.
