PC Engines range of models is a real mess...
JP version
PC Engine,
CoregrafX,
CoreGrafX II![](http://i62.servimg.com/u/f62/14/42/80/06/9fff4810.jpg)
First is white and then becomes anthracite black.
first output video with antenna RF. The others composite.
These plays japanese Hu card.
1989 :

Only slight differences between them (Duo is black, Duo R is white, RX comes with 6 button pad)
Can read obviously Hu card and CD rom2 games.
US Version
TurboGrafx - For US market

dedicated Hucard, not compatible with JP version.
It also exists TurboGrafx CD rom version, there's a crual lack of game.
Main problem with PC engine is their composite output.
In France the importator (sodipeng) did RGB modification for the inner market.
The RGB cable also included a RGB signals amplifier before arriving on scart.
Sodipeng is then a de facto DIN pinout standard.
Some models can be found on ebay with similar modifications.
CD Rom can be burnt CD-R.
I did buy the everdrive mentioned before. Works as it should.
I own a Duo RX version (from last year). It is RGB modded but also has a US/JP HU card switch.
it comes from

I also can't garantee trust with this seller.
