Own a piece of Mattel Intellivision History!

This Mattel Intellivision Computer Adapter unit (ECS, or LUCKi for those in the know) was used for game development and testing back in 1983. Preliminary design and testing of Wall Street (an ECS game that was never completed) happened on this unit.

Note that there is no Serial Number / FCC id sticker on back, as this unit was delivered internally within Mattel for engineering use.

Package includes main unit, keyboard, power supply, and Owner's guide.

This device has not been powered up in 40 years, so it is unknown if it still works.
