Magnavox Odyssey 2

The Odyssey 2 was born in 1978, and even though it didn't have as lucrative a following as the Atari or Colecovision, it still managed to have one million units sold by 1983. One of the main features of the Odyssey was the self-contained keyboard, which no other gaming console had at the time. This was to be incorporated into educational games. Mainly, the keyboard was used to select the different games and difficulty levels on the cartridges.
