One of them was intellicovision, they use a ROM cartridge that must be plugged in the console to play the games.

The hand-held controllers have not only the "joystick" (round button), but also 12 digits, and other buttons in the sides of the controllers , depending of the game those buttons are used for different purposes.
The games, ....

There were different games, from the typical shot-up (space invaders, space hawk, ...) to some sport games, like soccer or tennis .
This console was donated by Jesus Guillamon, a friend from Murcia, and still works :

The screen seems to be quite snowy , perhaps the video chipset has been damaged after so much time, but still it's possible to play the games.
