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.
Asteroids (video game)
A prototype of "Asteroids" was well received by several Atari staff and engineers, who would "wander between labs, passing comment and 
stopping to play as they went". Logg was often asked when he would be leaving by employees eager to play the prototype, so he created a second prototype specifically for staff to play. Atari went to Sacramento, California for testing, setting up prototypes of the game in local arcades to measure its potential success. The company also observed veteran players and younger players during focus group sessions at Atari itself. A group of old players familiar with "Spacewar!" struggled to maintain grip on the thrust button and requested a joystick, whereas younger players accustomed to "Space Invaders" noted they get no break in the game. Logg and other Atari engineers observed proceedings and documented comments in four pages.
"Asteroids" was released for the Atari 2600 and Atari 8-bit family in 1981 and Atari 7800 in 1986. Released in 1981, the 2600 port was the first game to use bank switching, a technique developed by Carl Nielsen's group of engineers that increased available ROM space from 4 KB to 8 KB. Brad Stewart, the programmer tasked to work on the port, used bank switching to complete the game. A port for the Atari 5200, identical to the Atari 8-bit computer version, was in development in 1982, but was not published.
