NEC released the Core Grafx in 1989 in Japan.

The Core Grafx is similar to the original PC Engine, but instead of having RF out, it has a port for composite video, using a pinout similar to the Sega Genesis/Mega Drive.

The Core Grafx is a famous system for collectors, as it was only released in Japan, and a few other European countries such as France.

The Core Grafx shares its game library with all the other systems of NEC, which makes it ideal for those wanting to get into collecting for the PC Engine.
