Well well well, I can't believe this actually worked!
I had an old NTSC monitor, and it had such a nice picture tube, I wanted it to be RGB.
Little did I know it was SO easy to pull off!
On the neck of the CRT, there are a bunch of wires going to it.. 3 of them are R, G, and B.. So, I spliced those, connected it directly to the Genesis.. Well, I knew at that point, I was still lacking one thing, the Sync.
So, since the H/V was still hooked up to the motherboard of the monitor, I hooked up the Composite video to the Composite video in jack.. This essentially just took the H/V sync, and it worked.. A nice RGB picture on the monitor.......well, almost..
The picture came out a little too bright, so I had to adjust the R, G, B CUT values on the neck.. A resistor probably was all I needed, 75Ohms to ground, as I essentially did bypass all that circutry.. But I was in a rush..
Daaaannnnggg, RGB is awesome! Too bad I can't do this mod to my HDTV, that will still need the RGB to Component adapter..

Please, if any of you want to do this to your old NTSC/PAL monitors, do check with the circuitry though.. I noticed not all my monitors worked this way, and didn't produce a picture...
