You may encounter this loot in a hidden cache west of Ranger Citadel, but this is just nothing but a waste in your bag so if you are planning on taking them, be ready to be encumbered...
You can give 1 to Quarex in the Rail Nomads Camp for $1000.
This is a rather humorous Easter egg which is in reference to the Atari game for which it is named. Widely considered to be the worst video-game ever created, it's sales were so poor that a truckload of them were collectively dumped in a landfill in New Mexico in 1983. Atari verified that about 700,00 cartridges were buried at the site, including E.T. The Extra-Terrestrial. The cache was excavated in April 2014 by Fuel Industries, Microsoft, and some others, revealing about 1,300 relatively undamaged items which were recovered. A small portion were given for curation, and the rest were auctioned off to help raise money for a museum to commemorate the burial.
