I spotted it on page 597 of the 1983 Sears catalog. “Two big names play the same games,” the headline boasted. Next to the venerable Atari 2600, Sears presented the Coleco Gemini, an Atari 2600 clone.
In 1982, Coleco built an add-on to make its Coleco Vision game system Atari 2600-compatible. Atari sued. And then Coleco poked the bear by making an outright clone. Sears had sold Atari 2600 clones before, but they were actually a private-label version of the real Atari 2600. The Gemini was more of a true Atari 2600 clone.
