+ | ====== Japanese RGB-15 Connector ====== | ||
+ | This connector is the standard for many pre-DOS/V (IBM compatible) computers in Japan. | ||
+ | |||
+ | **<color indianred> | ||
+ | |||
+ | **NOTE** the numbers are usually visible on the connector itself. | ||
+ | |||
+ | ===== X68000 ===== | ||

+ | ===== PC 9801 ===== | ||
+ | The PC-9801 connector is nearly the same as the X68000. | ||

+ | ===== CAVEATS ===== | ||
+ | * Not all systems put out power on pin 7. Normally +5v, some devices (like the X-RGB2) leave this pin disconnected. | ||
+ | * Remember that the pin numbers are almost always found on the connector itself. | ||
+ | * CRITICAL: H and V sync are TTL level (5Vpp) If you make a SCART cable and tie pins together, you must use a resistor (470ohm - NOT CONFIRMED) to lower voltages to safe levels for 75ohm / 0.3Vpp CSYNC or else you’ll damage the X68K or your display device (eg XRGB mini) | ||
