Console systems to Jamma.. yippie

I posted over on the KLOV.com forums a WTB thread. I asked for a broken Playchoice 10 board that had a good PPU. I'd just hat to cannibalize a working board.
Did you RGB mod an SNES? If so how. I read about some cables RGB scart cables, some have caps in them, some have different values, some don't at all. It's hard to nail down information on that. I have a US NTSC SNES.

Yea but I did it with a Mini US SNES though not sure about the original.

Bought the SNES cable from here http://consolegoods.co.uk/ They have the caps and the resistor in.

Let me know if you would like the exact European transistors mentioned in the guide. Would be handy to rule them out as being the problem.
However, that pic looks exactly like a screenshot I saw of someone who had wired the transistor incorrectly. Collector and emitter was swapped.

Yeah, I use the ultimarc for the nes.
Works great.
But don't run the sync through it!

You might still need to get a JROK sync cleaner.
The ultimarc RGB amp needs 5 volt fed into it. I just usually hook right to each leg of the capacitor to power the ones I use. I take all the connectors off the ultimarc amp and solder right to the pcb

I got ultimarc RGB amps in both of those NES projects, hopefully those pics will answer some questions

Well, try tapping sync from the yellow video out jack first, if that does not work, then get a sync cleaner and tap right into the PPU. Tapping sync from the yellow video out jack will work with some monitors, but not others.
You have the correct input pins circled on the Ultimarc RGB amp - Its VGA pins 1,2,3
I had grounding issues with the Ultimarc RGB amps, that is why I have like 3 grounds hooked up in the pics.

Woohoo, got it. What it ended up being was the way I was testing it. I wasn't drawing the +5v and GND from the NES itself to power my RGB amp and Sync Cleaner. Once I did that and tied both of them into those +5v and GND, the magic happened. Then I hooked it up to my RGB to YUV converter and it's all good. I see a couple of graphical glitches so I'll have to add the cap.
Thanks for the help guys.
