SNES->IIgs video cable

[alekusu@phantom.com (Alex Eddy)]

	I am trying to build a SNES multi out -> AppleColor RGB cable, 
but am having no luck at all. Below is the pinout config I am using:

	SNES multi out			GS RGB
	pin 1	(red video)	->	pin 2	(red video)
	pin 2	(grn video)	->	pin 5	(grn video)
	pin 3	(RGB synch)	->	pin 3	(comp synch)
	pin 4	(blu video)	->	pin 9	(blu video)
	pin 5	(GND)		-> 	pins 1, 6, 13 (red, grn, blu GND)
	pin 6	(GND)		->	RCA audio L/R GND
	pin 7	(SVHS Y)	->	no connection
	pin 8	(SVHS C)	->	no connection
	pin 9	(NTSC video)	->	no connection
	pin 10	(+5 volts)	->	no connection
	pin 11	(left)		->	RCA audio L
	pin 12	(right)		->	RCA audio R

	I see that on the standard IIgs RGB cable, pin 10 is also available.
What is this for?  With the above connection I get a dead black screen.
Also in the rec.games.video FAQ, it says that 200 ufd caps are required for
the red, grn, and blu video pins.  True?

	Anyone with suggestions, or who has successfully built this cable,
please post here or mail me at ace@deeptht.armory.com

Thanks,
