Nintendo GameCube technical specifications

Nintendo originally offered a digital video output on early GameCube models. However, it was determined that less than one percent of users utilized the feature. The company eventually removed the option from consoles manufactured after May 2004 (model number "DOL-101" and later).[1] Technical specifications[2][3][4]

IBM PowerPC "Gekko" processor
