 +====== N64 RGB Amplifier (IC Based) ======
 +
 +High quality RGB output from early NTSC (US/JP) Nintendo 64 systems is possible by building a simple video amplifier/​driver based off of the [[http://​semicon.njr.co.jp/​njr/​hp/​fileDownloadMedia.do?​_mediaId=364|NJM2267]]. ​ As a rule of thumb, **only** Nintendo 64 systems with serial numbers starting with **NS1xxxxxxxx (US)** or **NUJ133xxxxx (JP)** have the **'​VDC-NUS'​** or **'​VDC-NUS A'** ICs that exposes RGB output for use in this mod.  Newer models use different ICs that cannot be tapped for RGB modification. ​ Visit this [[http://​nfggames.com/​forum2/​index.php?​topic=3231.msg21527#​msg21527|thread]] for a serial number/RGB compat cross reference list.

 +===== N64 RGB Connections =====
 +RGB can be easily tapped from the underside of the N64 PCB, as indicated (C124, C125, C126)

 +===== Notes =====
 +
 +This modification has been tested out on several XRGB-3 units and a Sony PVM-2030 with perfect results! ​ Stock SHVC-010 cables can be used with the resulting system. ​ Note that the 220uF electrolytic capacitors used for NTSC SNES RGB cables are not necessary for connecting the RGB output from the N64.
