The same game as "classic" Battleship, but instead of your opponent telling you whether you have hit or missed, you enter the coordinates for your shot into the computer and it either flashes a red light and makes an explosion sound if you hit or a whistling sound if you missed.
Later versions added a "code book" with 100+ different ship layouts to speed up the initial setup of the game (in the original version you had to program in the coordinates for all of your ships manually).
If you are trying to determine which game board you have because your box is missing, here is a handy guide up to the 1989 version
1977 and 1979 (non talking)
1. The lettering near the on/off and the load/go switches is white
2. The battery section requires 2 - 9 volt batteries
3. There is no code book
4. Red plastic window is darker and the bulb is out of view
1982 (non talking)
1. The lettering near the on/off and the load/go switches is NOT white
2. The battery section requires 4 - AA batteries
3. There was an orange code book
4. Red plastic window is textured (on the back) and you can see the light bulb
