RGB SCART daughter board for the IF-C01COMG Clone board. This board also has support for a sync stripper circuit selectable by SW2. If enabled the LED in D1 will light up. Supported sync strippers are LM1881 and EL1883 (and whatever other pin compatible). LM1881 supports running directly off 12V and thus if using this, close the JP1 jumper with solder, and you can then skip U2 and its two capacitors C5 and C6. EL1883 runs off 5V, which must then be supplied by U2, and JP2 then needs to be closed instead. THEREFORE ONLY CLOSE EITHER JP1 OR JP2, NOT BOTH!

SW1 selects to route audio to stereo RCA plugs or to internal mono audio.

SW1 and SW2 can also be omitted and jumped accordingly (the switches are quite expensive…)

The mechanical slots for the SCART plug are hacked in due to OSHParks missing oval slot support. It should be good though.
