-==== The Pinout ​==== +===== Japanese 21-pin RGB connector ===== 
-{{http://​www.gamesx.com/​grafx/​conn_scartm.gif}}+The Japanese RGB-21 connector, also known as EIAJ TTC-003 apparently, is identical in appearance to the European [[scart_connector|SCART]] (or Péritel or Euroconnector). ​ The pinout is completely different however. ​ There'​s an RGB<- ->SCART adaptor pinout [[scart2rgb|here]].

 +  * *connect to pin 11 via 3.3k Ohm resistor. ​ The resistor isn't usually necessary, and +5v on this pin will most often work.

 +=== Full Version === 
 +This version includes every pin, including a few you'll never really need to know.  All labels are display-relative,​ so input means into the display. ​  
 + 
 +Most of these pins can be safely ignored for most purposes. ​
