Collection of ColecoVision Expansion Module #1 variants showing Atari 2600 compatibility adapters

Expansion Module #1 made the ColecoVision compatible with the industry-leading Atari 2600. Functionally, this gave the ColecoVision the largest software library of any console of its day. The expansion module prompted legal action from Atari, but Atari was unable to stop sales of the module because the 2600 could be reproduced with standard parts.
