NTSC N64 motherboard revisions that can be RGB modded:. In case those forums go offline, here’s an extract of the info we’re after. UPDATE – some extra info from Link83 about serial numbers, motherboard revisions and a whole heap of stuff here, this chap knows his stuff!! Getting the serial number is now a good way of finding if it’s RGB’able!

If your console can be modified then the chip at location U1 will have “VDC-NUS BU9801F” printed on it, if it can’t be modified then the chip at location U4 will have “MAV-NUS RS5C282 (or RS5C382)” written on it. You have to take your console apart ( Gamebit needed), remove all of the heat sinks and shielding etc until you can see the upper side of the motherboard. Unfortunately there isn’t a easy way of identifying if a console is compatible without actually opening it up (some people say that the later limited edition coloured consoles are generally not compatible). It can be added to some models of the console, it has to be an NTSC console (although there is an early French Secam model that is also compatible), be careful though – as there are a couple of different NTSC versions, only the earliest ones are compatible. The N64 console doesn’t officially support RGB.

This one links to this, which has ANOTHER RGB mod and Amp using the THS7314 Amp – This is now my preferred method for RGB’ing an N64. This page is here for historical purposes only, some newer alternatives now available here and here.
