NTSC N64 RGB Mod with THS7314 Amplifier
First you will need to use a Rev 03 motherboard. You can't get c-sync from a Rev 04 motherboard even though you can get RGB.
These are the confirmed N64's with Rev 03 motherboards :
NS100852325 - NUS-CPU-03
NS100883831 - NUS-CPU-03
NS100932881 - NUS-CPU-03
NS101568393 - NUS-CPU-03
NS102245156 - NUS-CPU-03
NS104885107 - NUS-CPU-03
NS105145712 - NUS-CPU-03
NS105519094 - NUS-CPU-03
NS105866648 - NUS-CPU-03
NS105993542 - NUS-CPU-03
NS107466808 - NUS-CPU-03
NS109807944 - NUS-CPU-03
NS115716209 - NUS-CPU-03
NS119128565 - NUS-CPU-03
NS122626751 - NUS-CPU-03
NS124591453 - NUS-CPU-03
NS127767114 - NUS-CPU-03
NS127855507 - NUS-CPU-03
NS127959472 - NUS-CPU-03
NS128695706 - NUS-CPU-03
NS130427562 - NUS-CPU-03
NS132070599 - NUS-CPU-03
NS133533895 - NUS-CPU-03
NS133598474 - NUS-CPU-03
If your serial number is in that range you should have a Rev 03 motherboard.
Now here is the part list of the items you will need for this mod:
1 - .1uF ceramic capacitor
3 - 75 ohm 1.4 watt resistors
1 - Smd SOP8 to DIP8 Adapter Converter board
1 - THS7314 3 channel video amplifier
These parts are available on eBay or DigiKey.
Now the reason we are using an 3 channel amplifier is to reduce the problems usually associated with the N64 Rgb mods.
Usually if you try to tap directly into the RGB on an N64 motherboard you will get a dark ugly picture. If you use the "internal amplifier" method of amplifying the signal you will usually get an over saturated picture and you can burn out the chip.
So if we add a small amplified circuit we can get as close to a perfect RGB signal as possible.
Now we need to attach the video amplifier to the converter board. We then add the .1uF ceramic cap and the three 75 ohm resistors.
I took a pic of the orientation and layout as it should be done :
Make note of how the video amplifier is soldered on in relation to the notch mark on the bottom of the converter board. This MUST be done exactly as I did in the pic.
The ceramic cap and the resistors should be attached where I have them also.
Now you will need to attach a ground, +5v , red, green, blue wire. These will be wired to the N64 motherboard.
You will need to attach them just like in this pic :
Here is where they are wired.
Ground = Left side of capacitor C74
+5v = Right side of C109
Red input = R8
Green input = R9
Blue input = R10
You will then need to attach the Red,Green,Blue,Ground wires that will be going out of the console to a Video Converter for your TV or PC Monitor.
Also you will need to attach a C-Sync wire for the Video Converter. The C-Sync wire is attached to the 3rd pin on the video out on the N64 motherboard. It is labeled on the motherboard with an "s". You can see it in the left hand side of the above pic.
Now you have an RGB modded system, but how do you get that into your new LCd TV ?
Well Arcade Parts makes a wonderful and relatively cheap solution :

You can attach the RGB/Ground/ and C-sync directly to this device and then run VGA to your LCD or Plasma. It runs off 5v-12v.
As you can see in my pic, you attach the R/G/B wires to the Red/Green/Blue wires on the upper right. Black goes to ground and white goes to C-Sync.
Change the Video Converter's input to RGBS. Change the resolution on the video converter to your desired resolution. Adjust colors/contrast/brightness/ etc as desired. Then Voila you have glorious RGB on your fancy new fangled TV.
