Never looked at an atari controller? What are the modders of this world coming too!?

I thought that the genesis 3 required modification for rgb... http://www.gamesx.com/rgbadd/genesis3.htm

I also have the same board as neverused.

As the G3 takes the standard 9-pin connector, the pins required are there - they just aren't actually connected on the console, kind of like the R-channel audio. It's there... but doesn't work. The G3 was mono-only.

However, yes, the console can be modified to output both S-Video and RGB video.

Thanks, Neverused, for the rulered pic

This board has excellent opportunity for reduction. Without any MAJOR component relocation, the board can be reduced to a 4.5"x3.5" footprint.

Here are the lines one would cut:

And close-up of the controller port area:



Edit: Oops. Obviously, one would not cut off one of the legs of the regulator when reducing the board size. So ignore my lower-left-corner cut line mistake.

I attempted an identical cut-down of the board like that, but isn't working. The only thing I left on was the place to connect the cartridge. I'm just hoping that I only cut away too much ground, and that I can reconnect the trace elsewhere.

If you cut along those lines, there should be no problem - got pics?

Hold on, I'll have them in about a half hour...

Okay, here we go. I relocated all my capacitors, and soldered in a game. (My cart slot wasn't working at the time). All of my stuff worked then. But I decided to cut my motherboard down, and now blank screen.




And yes, for the top picture I know the capacitor is screwed up in the top-righthand corner. But it worked even with it like that. It stopped working only after I cut the board. The game also isn't soldered in all the way, because I was in the middle of redoing it for a third time.

Heh, you've got the newer, non-heart-shaped board too.

Anyway, I see two areas of interest. The 7805 regulator looks a bit distressed; what did you use to cut the board down? If you used a high-speed cutter, like a Dremel, that can heat the board up hot enough to melt solder. Zooming in on the backside, it looks like the connections might be ok... but then, they might not be. One of the pins looks like it's come out almost completely. Check your connections with a voltmeter.

My next area of concern... did you remove the reset switch before or after you cut the board down? If you removed it after you cut the board down, that may be an issue there, depending on what type of switch the G3 used. If it's an interrupter, then that's your problem right there. If it completes a circuit when pressed, then not.

Edit: Just checked out mine, it shorts a circuit to ground, so I'm going to go out on a limb here and say that's not your problem.

I would take a voltmeter and see what's going on with the voltage regulator, make sure you're getting good ground, input, and output voltage. If you're getting all three, then the problems probably something to do with the cart connector. If you look at the backside picture of the cart connector of my G3, on the top row to the left, second pin from the left, there is a trace that wraps around the number 1 pin that traces to a capacitor, the one next to the IC3 label. I'm going to say that's a possibility. No big deal if you've cut through it, though. I can't tell from your pic if there was a trace there or not.

Edit #2: No trace was there, just looked at Neverused's backside pic. Check out that regulator, then get back to me.

perhaps the gnesis 3 has hidden layers?

Nope, it's definitely just two layers.
