When I was young my family had an early elctronic hand held game called Flashpoint.

It was simply a light blue calculator sized case with a grid of holes into which a probe on a wire was inserted. This would cause 1 of 3 lights to light up telling the player to move the probe either up, to the right or diaginally up & right. I never knew what the acutal point of the game was but it would almost always find it's way to the top right hand hole.

If anyone knows what I'm talking about please let me know.
