Arabian was manufactured by Sun Electronics and distributed by Atari. Not satisfied with a number of late 70s and early 80s hits, Atari decided to license a number of games from other manufacturers. Arabian was one of two games licensed by Atari from Sun Electronics, the other being Kangaroo.
Because these game boards aren’t made by Atari, they look different than Atari boards made in the early 80s. What is interesting however, is that Arabian has a pinout that uses the typical 44 pin and a 24 pin Atari connector configuration from this period. Also, like most other Atari and Sun Electronics games, Arabian has a unique pinout.
