According to this:
http://pinouts.ru/VideoCables/MacVideoToVGA_pinout.shtml, these are the Mac pins/sockets necessary for the video:
Wire Color - VGA - Signal - MacVid
Brown - 1 - RED - 2
Red - 2 - GREEN - 5
Orange - 3 - BLUE - 9
Blue - 11 - ID0 - 11
Yellow - 14 - VSync - 12
White - 13 - HSync - 15
1\ * Br * * R * * * /8
9\ O * Bl Y * * W /15
I'm still confused/worried about the function of the id0 (VGA 11), What does it do? Will sending the id0 signal to C/VSync Ground (Mac 11) work?
* On my adapter pictured in an earlier post, VGA 11 is not connected to any pin (nor the shield) on the Mac side. This is the adapter I used successfully to send video from the 460 and 475 to the 9"-mono-monitor, so I think I should not use the blue wire at all.
* On a different adapter I have (labeled "ADAPTER 21 640X480-1280X1024), VGA 11 is connected to the shield on the Mac side. I have not tried this adapter with any part of this set-up (460/475 to 9"-mono-monitor).
* On neither adapter is any pin on the Mac side connected to the shield.
On my working (first) adapter, Mac pins 7 & 10 are connected, so I should bridge them in my adapter cable, yes? The link above has a diode in-line, "pointed" at 7, should I incorporate that? Can I use my multimeter to determine if there is a diode in my adapter? I have my multimeter set to Ω, and it beeps and displays 0.000 (so, 0 Ohms of resistance, right?) both directions (red on 7 + black on 10, and black on 7 + red on 10).
Here's what I have so far:
My questions are: Do I need the diode, and should I take the IDO to Mac 11?
