Rebound (video game)
Development of "Rebound" began in late 1973, as one of several variations they produced in 1974 on the gameplay of the successful "Pong" (1972), Atari's first game and the fourth-ever arcade game. Around the same time, Atari launched Kee Games, a subsidiary meant to produce clone games of Atari's products and act as a competitor in order to expand into more distribution channels in the same region than the industry typically supported. Kee's first game, released in March 1974, was "Spike", a clone of "Rebound", which added a "spike" button to the game that made the paddle jump up and attempt to bounce the ball downwards instead of up. In addition to the base game, Atari sold a conversion kit to convert any Atari two-player "Pong" variant into "Rebound", and in 1977 "Rebound" was included in "Video Olympics" for the Atari 2600, a collection of "Pong" variants.
Atari 5200
Atari later decided to re-enter the games market with a design that closely matched their original 1978 specifications. In its prototype stage, the Atari 5200 was originally called the "Atari Video System X – Advanced Video Computer System", and was codenamed "Pam" after a female employee at Atari, Inc. It is also rumored that PAM actually stood for "Personal Arcade Machine", as the majority of games for the system ended up being arcade conversions. Actual working "Atari Video System X" machines, whose hardware is 100% identical to the Atari 5200 do exist, but are extremely rare.
