Sheen Video Game
The Sheen Video Game is a Pong-clone manufactured in Hong Kong and released in Australia in 1976 by Sheen.
The system includes two removable - but not fully detachable - paddle controllers, and a non-removable RF cable.
It has four built-in games, which include Hockey, Squash, Tennis and Hand Ball. They are all essentially Pong with minor changes. In addition to this, player can choose from two speed and two bat size options, switch the angle between 20º and 40º, and select between auto and manual serving.
The console can be powered by an external 9V DC power supply, or alternatively by six UM-1/D-sized batteries.
