The RGB adapter provides a standard, high density 15-pin VGA plug and brings to the top the standard Arduino headers for further expansion. Video is generated on the Propeller and fed through the 8 standard resistors on-board the RGB Adapter using the AUX port header. This leaves all the Arduino compatible pins free. There is an 8x2 cluster of pads to mount a header (not incl) which provides access to the 8 pins of the Propelle that are generating the VGA signal. The traces can be cut down the center of these rows to separate the VGA connector and resistor net from the Propelle. Doing this could provide an insertion point for further signal processing, or jumpers.
