TriGem Computer Inc. (, abbreviated TG, also known as TG Sambo), was a South Korean personal computer manufacturer and technology company. Established in 1980, TriGem was the first Korean company dedicated to manufacturing computer systems. It delivered Korea's first microcomputer in 1981 and the first Korean IBM PC compatibles in 1984. From that point until its breakup in 2010, it alternated between the first- and second-largest computer manufacturer in South Korea, competing with Samsung Electronics.
