Xonox

Xonox, a division of K-tel Software, was an American third-party manufacturer of cartridges for the Atari 2600, ColecoVision, Commodore 64, and VIC-20 in the early 1980s. Xonox was one of many small video game companies to fold during the Video Game Crash of 1983.

== History == Xonox, based in Minnesota, started developing Atari cartridges during the height of the 2600's popularity. Xonox capitalized on the novelty and perceived value of "double-ender" cartridges. These could be inserted into the console on one of the two ends, each end offering a different game. Different double-ender configurations could package the same game with different counterparts. Xonox was not the first company to try this; Playaround did it earlier with their adult-themed titles. Xonox eventually abandoned this idea and began releasing single versions of some of the titles previously offered as double-enders as well as a few new titles.
