Editing ColecoVision (section)

==== Atari 2600 expansion ====
''Expansion Module #1'' made the ColecoVision compatible with [[Atari 2600]] cartridges and controllers.<ref name="eg198306"/> It leveraged the fact that the 2600 used largely off-the-shelf components and was effectively a complete set of 2600 electronics, including a [[reverse-engineered]] equivalent of the 2600's sole custom chip, the [[Television Interface Adaptor|TIA]]. The ColecoVision console did not do any translation or processing of the game code on the 2600 cartridges; it only provided power and clock input to and audio/video output from the expansion module, which was otherwise entirely self-contained and could be thought of as the first Atari 2600 clone console. Functionally, this gave the ColecoVision the largest software library of any console of its day. The expansion module prompted legal action from Atari. Coleco and Atari settled out of court, with Coleco becoming licensed under Atari's patents. The royalty-based license also applied to Coleco's [[Coleco Gemini|Gemini game system]], a stand-alone clone of the 2600.<ref name="nyt-pact">{{cite news|title=Atari-Coleco Pact|url=https://www.nytimes.com/1983/03/12/business/company-news-atari-coleco-pact.html|work=the New York Times|date=12 March 1983}}</ref>
