sega saturn rgb

[phizzler1981]

i have a Wells Gardner D9410. its a multisync monitor, 27" i believe. capable of frequencies from 15Kh to 31Kh. it has a vga out on the back. i recently disassembled my MAME cab cause i moved. long story short, im wondering if there is a way to either mod my saturn or buy some kind of cable to connect it to the WG9410.

ive studied this page here:
http://www.gamesx.com/avpinouts/saturnav.htm
and for the life of me, i dont understand what the hell this guy is doing. using a 9pin mini sub? the details are vague as fuck. can anyone shed some light for me?

I think you need to make your own cable (at least, I did, even after buying a scart-d-sub cable and finding it wired completely wrong). There are several guides on doing it. I was mostly following this one when I made mine:
http://forum.arcadecontrols.com/index.php/topic,77370.0.html
Tho using that picture on the page you linked, you could look up a pinout of a d-sub connector (make sure it's telling you if it's the plug end or wire end) and just match up the pins.
If you get a good (there are bad ones) Saturn SCART cable and pull the scart end off, vou'll have the male saturn plug already so you can just buy a VGA-D-sub end to solder the wires to.

Here's another guide I didn't follow:

I'm hooking VGA up to a 1084 amiga monitor, and had to merge the horizontal&vertical sync to make a composite sync signal, but otherwise the wiring is mostly the same...

hi phizzler , does your MAME Cab have JAMMA wiring and a JAMMA connector ?


if so take a look at viletims SCART to JAMMA Adpater , pretty much anything SCART will work PSX PS2 DC GC XBOX360 SATURN WII

If the monitor has a VGA port on the back, find a VGA pinout and wire to that.

You might need a sync seperator circuit to get HSync and VSync out of the Composite Sync on the Saturn.

Let's hope it's not a PAL Saturn. Only had composite video for sync.

You could always toss in a sync stripper if that's the case.

ok, its not a PAL and no jamma connections on the WG9410. im not fully versed in how to make any type of cable (like what to buy or where to start), nor do i know the avg cost of an scart cable. this sounds like it might be a project ill end up screwing up. shit. can i not take the end of a saturn av cord (the 10pin part) and rewire the other end to a 15pin? or am i gonna need an scart cable no matter what?

ive also found the vga pinout for the monitor if that helps at all

You don't need a SCART cable at all, they're just plentiful and relatively cheap so you'd be guaranteed to get a cable & plug with all the pins connected to wires (rather than trying to buy the correct plug, 10 wires and a long shrink-wrap for them all). You need a proper plug for the back of the Saturn to get all your wires connected and a scart cable will have that. You could make up a female SCART-to-d-sub cable and use it to connect the Saturn as well as many other consoles into your monitor (Genesis, SNES, PS1, PS2, Dreamcast, XBOX, etc.), but if Saturn's all you're interested in, you can get a Saturn SCART cable, cut the SCART plug off, and connect the wires to the correct pins of a d-sub (VGA) plug.
AppleQueso mentioned a sync splitter and looking at the manual, it appears you will need that wired into the cable (Saturn has composite sync - horizontal and vertical combined, and your monitor seems to need the sync on 2 separate pins). I know there's one wire on most all video connectors that has some voltage in it - for the saturn it's pin 4 on that diagram, so it should be possible to make that circuit work without providing external power. Aside from that you should be able to just wire the rest of the pins straight across to the correct pins on the d-sub plug.

I've always received high quality cables from retro_console_accessories - http://www.retro-access.com/ and Rob Webb @ ConsoleGoods. I hear Playasia is reliable as well.
over half of the SCART cables I bought from other places were duds. Incorrectly wired, missing the capacitors and/or missing the necessary sync wiring.

Reguarding Retro_console_accessories - considdering the professional job they do of making up all their cables and the fact that they do modding services, they might be willing to custom-make the cable you're looking for.

I had to spend an hour or so on Google to find the right wiring diagrams for the cable I made up for my 1084 monitor. I expect there's several people that have done exactly what you're planning to do. Most of the useful, correct information I found was on the Arcadecontrols forum. Those guys are very well versed in connecting arcade monitors to all kinds of hardware.

Reguarding the sync splitter, I think this is one:
http://www.nexusuk.org/projects/vga2scart/circuit
because to make a useable composite sync, I just soldered the horizontal and vertical sync wires together...

If you're not thoroughly confused yet, one last note - Japan and Europe have different wiring for their SCART plugs - Only use European SCART.

I am new to RGB but I think a Sync Strike will do what you want. So you would just need a Saturn RGB SCART cable and one of these. You probably won't need an external power source because I believe most SCART cables carry the necessary power on one of its pins. But if you do need external power, 5V ac adapters aren't hard to come by.

Again, I am new to this and I don't have one of these yet but I may get one in the near future to play with. Hopefully someone else will chime and say whether this will work or not.

Ah, yeah, I wasn't thinking, the Sync Strike has a LM1881 chip in it and would do the trick. My previous link about the sync-splitter was wrong
It's way easier to buy a Sync Strike than to build the circuit yourself. I once tried to make the same thing on bread board (before the Sync Strike existed) and never did figure out what I did wrong. I'd say getting a sync-strike is money well spent.
I agree with bmoc. You should be able to just combine a Euro Saturn SCART cable, a Sync Strike and a standard VGA cable to do exactly what you want.
If it doesn't work, you'd need almost the same thing, but with a EL1883 chip instead to get both horizontal and vertical sync.
