There is one bat per side, a top and bottom boundary, and a center net. The individual scores are counted and displayed automatically. Considering the option where all bats and four angles are used, after the reset has been applied, the score will be 0-0 and the ball will serve arbitrarily to one side at one of the angles. If the ball hits the top or bottom boundary it will assume the angle of reflection and continue in play. The player beeing served must control his bat to intercept the ball. When a hit is detected by the logic circuit, the section of the bat which made the ball contact is used to determine the new angle of the ball. To expand on this, all bats are divided logically into four adjacent sections of equal length. When using the four angle option, it is the quarter section of the bat which actually hits and determine the new direction of the ball. The direction does not depend upon the previous angle of incidence. With the two angle option, top and bottom pairs of the bats are summed together and only the two shallower angles are used to program the new direction of the ball. The ball will be then sent back to the other player, bouncing on top and bottom noudaries as necessary until it reaches the other player.

This action is repeated until one player misses the ball. The circuitry then detect a score and automatically increments the correct score counter and updates the score display. The ball will then serve automatically towards the side which has just missed. This sequence is repeated until a score of 15 is reached by one side, meaning the end of the game. The ball will still bounce arround but no further hits or scores can be made. While the game is in progress, 3 audio tones are generated by the system to indicate top and bottom reflections, bat hits and scores.

text: With this game each player has a keeper and a striker. The layout is such that the keeper is in his normal position and the striker is positioned in the opponent's half of the playing area. When the game starts, the ball will appear going from one goal line to the other side. If the oppoenent's striker can intercept the ball, it will shoot it back towards the keeper. If the ball is missed, it will go to the other half of the playing area. The first team's striker will have then the opportunity to intercept the ball and deviate it at a new angle according to the playing option used. If the ball is intercepted by the keepr or it bounced back by the end-field boundary, the same striker will have another opportunity to intercept the ball and send it back to the keeper. A score is made by shooting the ball through the defined goal area. The circuitry then detect a score and automatically increments the correct score counter and updates the score display. The ball will then serve automatically

A classic german pong system which uses the GI AY-3-8500 chip, thus playing the 4 basic pong games. No shooting games here... Something rare for that time, the two tiny controllers are not hardwired to the system. This means that when one of them died, it wasn't necessary to change the whole system.
|
|
|
|
The shape of the case is weird. It looks like a case conceived for a small computer. Indeed there's enough room for a small keyboard instead of the actual panel control, and the bulk at the back could have contained a mother board or any other hardware...
|
|
|
|
Actually, this bulk is used to store the controllers when the system is not used, and there's also the cells compartment.
|
|
|
|
When the system is opened, one can observe that under the control panel, several holes in the plastic case are not used by the system and are hidden by the black plastic film. For example there are two other holes for addtionnal controllers plugs. It thus can be imagined that the same case could have been used for 4-players game systems...
|
|
|
|
It is also interesting to note that many different brands used this particular case. The [Conic TV Sports TG-621](/museum/conic-tv-sports-tg-621/) for example is the same system.
