Looking for a game console from the late 1970's.?

My brother bought a game console during the late 70's early 80's. It was a triangular system and the cartridges were triangle shaped and fit flat on top. Each side of the console had different controls. One side had a gun for shooters, one side had a steering wheel for racing, and another had paddle controls. This was when everyone was getting the atari 2600. I just can't remember the name of the system or who put it out. If anyone out there remembers this let me know.
