Product Highlights

• Official Vintage Coleco Hardware: A 100% genuine, original 1980s factory production Model 2405 expansion unit. Not a modern clone, reproduction shell, or third-party adapter.

• Massive Library Expansion: Plugs directly into the front expansion slot of your standard ColecoVision console, instantly allowing you to play original Atari 2600 cartridges using your ColecoVision controllers or compatible standard joysticks.

• Fully Bench-Tested & Working: Rigorously tested with multiple vintage Atari 2600 game cartridges to verify stable power delivery, seamless cartridge slot connection, and crisp video/audio pass-through.

Hardware Condition Statement (Super Clean / Tested Working)

• Operational Status: Fully functional. The cartridge slot pins are tight, clean, and completely free of corrosion, reading game cartridges instantly on the first insert. The main interface connector fits securely and snugly into the host ColecoVision console.

• Cosmetic Condition: Super clean cosmetic shape. The exterior plastic housing has been thoroughly detailed, retaining its original deep dark coloring with virtually no scuffing, scratches, or stress fractures. The front silver and black accent faceplate is crisp, flat, and legible, showing only the lightest, superficial handling wear consistent with minimal vintage use.

• Maintenance & Care: The internal board has been blown free of dust and the cartridge contacts have been treated for optimal connectivity. No cracked solder joints or leaking components were found during inspection.

• Storage Environment: Maintained strictly inside a smoke-free, pet-free, and climate-controlled hobby facility completely away from direct sunlight, dampness, or UV exposure.
