The PC Engine and TurboGrafx-16 are 8-bit consoles from the fourth generation of video game consoles.

Designed by Hudson Soft and manufactured and sold by electronics giant NEC, the console was initially released in Japan as the PC Engine on October 30, 1987 and was released in North America as the TurboGrafx-16 on August 29, 1989, followed by planned European release as the TurboGrafx but was cancelled. The console used small credit card-sized cartridges known as HuCards and was also the first console to play games on optical media via a CD-ROM expansion, first released in 1988. It was also the first console to have a handheld variant — the PC Engine GT and TurboExpress — which could play the same games as the home consoles. At least 17 different model variations were released, with the most significant models being part of the PC Engine Duo and TurboDuo line which incorporates the CD-ROM² add-on directly into the hardware. Although it was a success in Japan, the console saw sluggish sales in North America and was discontinued there by 1993. NEC and Hudson would unsuccessfully follow up on the PC Engine with the 32-bit PC-FX in 1994, but the PC Engine continued to see releases in Japan until 1999.
