WTB: RGB Moddable N64

[Helpplease]

Looking for a N64 that can be modified to output RGB, anyone have one? Even if it's just the motherboard I buy it from you.
Gonna see if I can mod a Pikachu N64 and add a internal RGB to HDMI converter so one can easily connect it to modern TV's.

I could go more into the details of the build, what I'm looking for is a N64 motherboard of the right revision that have the VDC-NUS so it can output RGB with a simple mod.
So I'm only looking for a N64 with revision NUS-CPU-01 to NUS-CPU-04.
Then I plan to add one of these inside of the N64.

It should work out pretty good and would make it alot easier to connect the N64 to a modern TV.
No worries that it won't fit, I will use a orange Pikachu N64 as they have alot more room in them.
Yes I will swap out the motherboard in the Pikachu N64 to one that can be rgb modded.

Just did this mod myself, without HDMI. You'll find that the VGA has a strange 15Hz signal that most monitors won't be able to sync to. On top of that, converting to VGA improves your image quality drastically, but going to HDMI will most likely reduce it again. Just put in RCA connectors instead of Nintendo's proprietary jack, EVERY TV has RCA.

AH, YOU DID THE MOD YEAH?

It's not VGA, silly, it's 15khz standard RGB. That's not strange, that's normal. Pure coincidence that the VGA monitors we have can sync to it.

Wait, so Beta, are you saying one only needs to wire up the RGB lines to VGA and hook it up to a 15hz compatible display?

 

[Bibin]

Beta doesn't know what he's talking about.

As long as a display accepts 1) composite sync and 2) 15khz h-sync (part of the c-sync signal) it should work fine, but the image will be dark and depending on where you pulled it, blurry or washed out. Proper amplification is required for it to work properly.

Oh *Can'tSayThisOnTV* yes. I've been needing a solution like this for so long. Thanks for explaining; would I just use the Y signal as the sync signals?

Actually, in this situation, I have the TV taking the composite input. I just cut the RGB lines and spliced in the N64 RGB from the BNC plugs I mounted on the back. As far as the TV knows, it's still displaying normal composite video on screen (which is why the derived sync works fine)

 

[Bush]

Okay, so provided I have a 15hz capable monitor, how would I wire up VGA?

 

[Bibin]

Put composite sync to the h-sync pin (pin 13), solder pins 5-10 to ground, and RGB goes to pins 1, 2, and 3.
