So...
On the 315-5788 chip, luma should be on pin 22 and chroma on pin 17. I'd try it but I don't have a display capable of doing S-video. Let me know if it works.

can I ask where you got this info.If this works it will be awesome.Much easier than my original plan ,which I still haven't gotten around to.
I bought "a lot of original Sega documents and test equipment" from a guy. I don't know what that includes in detail (I haven't had a chance to pick it up yet). I asked him to look the 32X S-video pins for me and that's what he said.
More of what's included when I get my hands on it.

It will be like you have a 61 inch RGB monitor. Because it takes the analog RGB signal, and converts it to 480p. Because the analog RGB signal is a much better signal to start with, the picture quality is "extremely close" to a native RGB signal.
It should at the very least be better than the S-Video signal.
I actually just bought a XRGB-2 that I will get later next week. As soon as I experiment with it, I'll report back.
FREAKING RGB
RGB rocks!
too bad i can'tuse it with the TV's in my home, or shop, or 99% of my customers sets...

it shows pin 17 to be an input to select 50/60hz .
I think there's an error on pin numbering on the page. It should go like this:Originally Posted by gcl1984
1 - -32

16- -17
So the 50/60 pin is actually pin 32.
I've received the docs but I really haven't had a chance to read/scan them due to all this real life crap I've had to do recently. But some day, some time...
You are most definately right. Even when I was looking at the chip in the 32x I didn't realize that.I feel kinda stupid.
The world would be a better place if you looked through those docs.
What the blue hell is the point of 50/60 modding a 32x? I mean, if it'd actually let me play darxide, that'd be somethin'...but i mean, most 32x games are barely worth playing anyway, and i booted Alien soldier on a 32x with the genesis itself region modded...Originally Posted by gcl1984
Well, I don't know if anyone else has tried this yet, but I just did... and... nothing.Originally Posted by davidleeroth
Well, not exactly nothing... I soldered a wire to 22 & hooked it to the luma in on my 1702. With brightness at full I can see a picture, but the signal is so low it won't sync. For kicks I tried the chroma as well but with the image so unstable & dim I can't tell if there is any color there.
I tried a few other points that 22 is connected to but it was the same story on each of them.
I tried with pin 22 both connected & disconnected to it's pad, same results either way. However, when disconnected the composite out is killed, so it must be somewhat important.

An amp would probably help.
1702 = Commodore 1702 monitor, a bench tester's best friend.
and this is where i suck. heh.Originally Posted by FABombjoy
Hrm, how do you guys figure out how to build those amps?
I admit i'm a hack job, i just do what the schematics tell me :P
1084 is my bench tester, heh.
why not just use the same amp that is used for the neogeo/genny?
That circuit really isn't much of an amp, it's more of a buffer.
The Y/C signal outputs on the CXA1145 are at the correct levels, but they are insufficient to feed a monitor. It actually looks pretty good until there is a lot of brightness on the screen, then the picture destabilizes and goes to crap. Hence the need for buffering.
The pic coming off the 32x is so low it needs an amp (or something else).
Oh ok ,thanks for the clarification .
How bout this
Seriously, tho. The existing signal needs some analysis; just throwing random circuits at it is a sure-fire way to waste a lot of time. Might as well try the circuit featured in this movie.
