TurboGrafx-16, fully titled as TurboGrafx-16 Entertainment SuperSystem and known in Japan as the PC Engine (PCエンジン Pī Shī Enjin?), is a video game console developed by Hudson Soft and NEC, released in Japan on October 30, 1987, and in North America on August 29, 1989.
The TurboGrafx-16 has an 8-bit CPU and a dual 16-bit GPU; and is capable of displaying 482 colors simultaneously, out of 512. With dimensions of 14 cm × 14 cm × 3.8 cm (5.5in × 5.5in × 1.5in), the NEC PC Engine holds the record for the world's smallest game console ever made. (Guinness World Records Gamer's Edition (2008))
In the United Kingdom, Telegames released a slightly altered version of the US model simply as the TurboGrafx around 1990 in extremely limited quantities. Although there was no full-scale PAL region release of the system, imported PC Engine consoles were largely available in France and Benelux through major retailers thanks to the unlicensed importer Sodipeng (Société de Distribution de la PC Engine, a subsidiary of Guillemot International).
In 2009, the TurboGrafx-16 was ranked as the 13th greatest video game console of all time by IGN.
