TENNIS 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. /media/museum/software/gi_ay-3-8500_tennis.gif

FOOTBALL Also called soccer and hockey 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 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. /media/museum/software/gi_ay-3-8500_football.gif

SQUASH This is a two players games. Players alternately hit back the ball into the playfield. The right-hand player is the one that hit first, then it goes over to the other player. Each player is enabled alternately. /media/museum/software/gi_ay-3-8500_squash.gif

SQUASH PRACTICE This game is similar to Squash except that there is only one player. /media/museum/software/gi_ay-3-8500_squash-practice_ss.gif

Wayne Keith (Abilene, TX) Wednesday 9th September 2015 My family bought this game new, and I still have it with box. The price tag says $38.97 (circa 1978). It does not have the AC/DC plug in converter, but does run with batteries. I''m not sure if the converter has been lost, or if it was an accessory we never owned (the box does not mention it). The output is VIDEO ONLY, sound is generated from a speaker in the console (with no volume control). Game play sometimes has observable bugs, such as balls continuing to spawn after end of game, and score continuing to increment. Still, it is a very playable version of Pong and has been a very reliable unit for the last 35+ years.

Matt B (mb7241) (Cleveland, TN) Monday 11th October 2010 I won one of these at an auction a while back, boxed, for about $10 or so. As far as I''ve seen and researched, it seems that a boxed one is only worth about $10-$20, and about half that for unboxed. Very fun to play, by the way...I''m from the generation after these systems came out (born in 1985), and I still pull this out and play it from time to time.

A classic pong from Roberts with four games (hence the name of the system) and detachables paddles. Made in Japan. The difference between the Rally IV and Paddle IV are unclear. Can anyone help ? Both systems seem identical despite a different cosmetic design : same chipset, same games, same controls, switches and buttons, etc...

The console is plastic with nice woodgrain accents. A knob allows you to select from the four games. There are two buttons, one for reset and one to serve the "ball", and five switches: power, serve (manual/auto), speed (fast/normal), angle (wide/narrow) and bat size (small/large). There are two wired paddle controllers which can be mounted to each side of the cabinet, or removed. These remote controls are only equiped with a small dial. The games selection is made through a knob... This game runs on either six C-cell batteries, or a 9-volt adapter with a 1/8" jack.

COMMERCIAL TEXTS (same as Paddle IV):
- Featuring 4 games with detachable remotre control
- Automatic on screen scoring
- Simply attached to your black & white or color TV set
