What makes the KC89C72 datasheet truly interesting, however, is what it omits. It does not tell you that this chip, when overclocked, produces a gritty, aliased distortion that modern musicians covet. It does not mention that the envelope generator has a quirk—a hold time that is slightly shorter than the Western original, giving Soviet-made music a unique rhythmic lilt. It provides no history of the factory workers who assembled these chips with outdated lithography machines, breathing microscopic dust that would later be diagnosed as a rare lung disease.
