While looking online for pictures of the Atari 2700, I found a picture of yet another 2600 prototype, the Kee Games Programmable Game System. I must say that this is quite the brightly colored console. I don't remember ever hearing about Kee Games before, so I decided to check out some info about them. The Wikipedia
entry appears below. Interesting that this company was an offshoot of Atari. Cool bit of gaming history.
Kee Games was an arcade game manufacturer that released games from 1973 to 1978. Kee was headed by Joe Keenan, a long-time friend of Atari co-founder Nolan Bushnell. Keenan managed to hire several defectors from Atari, and began advertising itself as a competitor. In reality, Kee Games was a wholly owned subsidiary of Atari, created in response to the pinball and arcade distributors of the time who demanded exclusivity deals. Kee Games released several "clones" of Atari games, allowing Atari to "exclusively" sell games to two distributors at once.
In December 1974, the relationship to Atari was discovered by the public. However, Kee's Tank game had been so successful that the distributors wanted to buy the game even without an exclusivity agreement. At the same time, Atari was having financial and management problems, while Joe Keenan had been very successful managing Kee Games. The two companies merged, with Keenan promoted to president of Atari running the business side of things, and Bushnell focusing on engineering. Atari continued to use the "Kee Games" label to release some of their games until 1978, but from the merger on, the games were clearly labelled "a wholly owned subsidiary of Atari, Inc."
