Motherboard has PAL oscillator and Adapter has NTSC oscillator = bridge JP1-pin with XCLKEN-pad (PAD 1)\n    2. Motherboard has NTSC oscillator and Adapter has PAL oscillator = bridge JP1-pin with OE-pad (PAD 3)\n\nPlease note, using a jumper-wire is completely optional, You can switch ECS Agnus in Early Startup menu or with software such as Degrader and then you only control the external XLCK-crystal enable or disable via the switch on the adaptor. However it can be more convenient to have both tasks controlled from one single switch, hence connecting a jumper-wire.\n\n***\n\n\u003ca href=\"images/SEGA_Mega_Drive_2_SCART_lead_pic1.jpg\"\u003e\n\u003cimg src=\"images/SEGA_Mega_Drive_2_SCART_lead_pic1.jpg\" width=\"400\" height=\"400\"\u003e\n\u003c/a\u003e\n\u003ca href=\"images/SEGA_Mega_Drive_2_SCART_lead_wiring.jpg\"\u003e\n\u003cimg src=\"images/SEGA_Mega_Drive_2_SCART_lead_wiring.jpg\" width=\"400\" height=\"400\"\u003e\n\u003c/a\u003e\n\u003cbr /\u003e\n\u003ca href=\"images/SEGA_Mega_Drive_2_SCART_lead_pic2.jpg\"\u003e\n\u003cimg src=\"images/SEGA_Mega_Drive_2_SCART_lead_pic2.jpg\" width=\"400\" height=\"300\"\u003e\n\u003c/a\u003e\n\u003ca href=\"images/SEGA_Mega_Drive_2_SCART_lead_pic3.jpg\"\u003e\n\u003cimg src=\"images/SEGA_Mega_Drive_2_SCART_lead_pic3.jpg\" width=\"400\" height=\"300\"\u003e\n\u003c/a\u003e\n\nSuitable SCART-lead to use with the adapter (originally for the SEGA Mega Drive 2, (Genesis 2) with AC coupling inside) \u003cbr /\u003e\nhttps://www.aliexpress.com/item/1005007360209844.html\n\n***\n\n\u003ca href=\"images/Amiga_RGB_video_splitter_pic2.jpg\"\u003e\n\u003cimg src=\"images/Amiga_RGB_video_splitter_pic2.jpg\" width=\"256\" height=\"192\"\u003e\n\u003c/a\u003e\n\u003ca href=\"images/Amiga_RGB_video_splitter_pic3.jpg\"\u003e\n\u003cimg src=\"images/Amiga_RGB_video_splitter_pic3.jpg\" width=\"256\" height=\"192\"\u003e\n\u003c/a\u003e\n\u003ca href=\"images/Amiga_RGB_video_splitter_pic4.jpg\"\u003e\n\u003cimg src=\"images/Amiga_RGB_video_splitter_pic4.jpg\" width=\"256\" height=\"192\"\u003e\n\u003c/a\u003e\n\u003cbr /\u003e\n\u003ca href=\"images/Amiga_RGB_video_splitter_pic5.jpg\"\u003e\n\u003cimg src=\"images/Amiga_RGB_video_splitter_pic5.jpg\" width=\"256\" height=\"192\"\u003e\n\u003c/a\u003e\n\u003ca href=\"images/Amiga_RGB_video_splitter_pic6.jpg\"\u003e\n\u003cimg src=\"images/Amiga_RGB_video_splitter_pic6.jpg\" width=\"256\" height=\"192\"\u003e\n\u003c/a\u003e\n\u003ca href=\"images/Amiga_RGB_video_splitter_pic7.jpg\"\u003e\n\u003cimg src=\"images/Amiga_RGB_video_splitter_pic7.jpg\" width=\"256\" height=\"192\"\u003e\n\u003c/a\u003e\n\u003cbr /\u003e\n\u003ca href=\"images/Amiga_RGB_video_splitter_PCBs.jpg\"\u003e\n\u003cimg src=\"images/Amiga_RGB_video_splitter_PCBs.jpg\" width=\"386\" height=\"290\"\u003e\n\u003c/a\u003e\n\u003ca href=\"images/Jumper_wire_to_JP4_pad.jpg\"\u003e\n\u003cimg src=\"images/Jumper_wire_to_JP4_pad.jpg\" width=\"386\" height=\"290\"\u003e\n\u003c/a\u003e\n\u003cbr /\u003e\n\u003ca href=\"images/Amiga_RGB_video_splitter_filterOff.jpg\"\u003e\n\u003cimg src=\"images/Amiga_RGB_video_splitter_filterOff.jpg\" width=\"386\" height=\"290\"\u003e\n\u003c/a\u003e\n\u003ca href=\"images/Amiga_RGB_video_splitter_filterOn.jpg\"\u003e\n\u003cimg src=\"images/Amiga_RGB_video_splitter_filterOn.jpg\" width=\"386\" height=\"290\"\u003e\n\u003c/a\u003e\n\u003cbr /\u003e\nFilter OFF vs. Filter ON\u003cbr /\u003e\nWith the THS7374's filter activated you can clearly see that the vertical jailbars are gone (right picture).\n\n***\n\nWhen ordering from JLCPCB select:\n\nSpecify Layer Sequence: Yes\n\n    L1(Top layer):    F_Cu.gbr\n    L2(Inner layer1): GND_Cu.gbr\n    L3(Inner layer2): VCC_Cu.gbr\n    L4(Bottom layer): B_Cu.gbr\n\nRemove Order Number: \n\n    Specify a location\n\nThis will notify JLC where to put the order number, they will replace the \"JLCJLCJLCJLC\" silkscreen label.\n\n***\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjbilander%2Famiga_rgb_video_splitter","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjbilander%2Famiga_rgb_video_splitter","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjbilander%2Famiga_rgb_video_splitter/lists"}
