Verault on eBay sells these Apple IIc connectors that claim to improve the video output via composite.
I'm wondering if this adapter just takes the pin 12 NTSC video output from the 15-pin connector on the back of the IIc and connects it straight to composite. Or is there some additional logic going on inside the adapter he sells. The item shipped for me is $50; if it turns out to be just a straight though then the cost is a bit high.
Above is from the IIc schematic. "VIDOUT" goes to the composite connector, while "NTSC" goes to connector's pin 12 on the back of the IIc.
This would lead me that the NTSC signal is going straight to the composite connector for the adapter being sold on eBay. (Maybe a resistor or capacitor is added).
If so, I'm also wondering if the NTSC signal output is indeed better quality than VIDOUT as the seller claims, and if so why?
UE1 VID 1 is part labeled 303-1001 on the package, there are no schematics for it.
Anyone know how pin 8 and pin 9 differ on the output, or can any shed any light on this subject? Thanks!
