Does anyone know how to hook up a WG D9800 to a JAMMA board? Do I need to buy anything special or is there somewhere on the back of the monitor I can hook up the jamma connections? All I see is the VGA input.
 
Post of a pic of the area where the VGA input is. if it's what i think, I can tell you once I see the pic...
 
A D9800 should have VGA and EGA\CGA inputs. It should have a small board mounted on the right hand side of the frame (as your facing the back of the monitor) where all these inputs plug in.

That's what I figured, just like the D9200. Once he posts a pic, i can illustrate exactly how to do it...
 
There is a Wells chassis that has VGA and EGA\CGA inputs on the main board. Now that I think about it the D9800 might be that chassis... I've got one at my shop so I'll take a look at it when I get there.

So much for that idea. The monitor I have is a D9400...

Well I was about to take a picture when I noticed those prongs there behind the vga adapter that I are compatible with JAMMA, so disregard folks! If anyone would still like me to snap a photo for reference I can.

You still may have to move a jumper for those prongs to work...
 
I'd like to know

Hi. I just got a D9800 and connected it up today. I do have some dedicated game boards I want to use with the monitor.

I noticed the pins behind the VGA connector, however:

The D9800 connector is 8 or 10 pins (sorry the game is elsewhere), but the connector from JAMMA has only 6 female pins. I connected this to the leftmost pins and there are 'wiggly' lines behind the "no signal" screen, but no game image.

If there is a jumper or other setting, I don't know. The D9800 didn't come with a manual and there are none online I can find.

Please, if someone knows, let us know!! Thanks!
 
Like I said before, post a picture of this pin area. If it's like the other tri-sync monitors they put out, there is a connector you have to move....
 
A jumper

Sorry still no photo... too dark for cell....

However, there is a label: Sync Select -- and it shows jumper positions for Interlaced and Standard.

Does that help?

Thank you
 
maybe I'm entirely stupid, but I thought the WG tri-syncs autosensed the resolution. I don't remember there being a jumper, just the little input board.

I also say this cause a user had a problem with their D9200 (I think) where it constantly say NO SIGNAL and as per my urging I told them to hook a CGA/EGA game to it, and it fixed their problem on the VGA.

I guess sometimes you have to alternate between them. curse the memory in these.

and no, the Interlaced/Standard will not make a difference in this case.
 
Hmm

Thanks for the info.

It's just as well as I could not find the jumper in question. I've been able to find one jumper on the board, and it did nothing.

The board diagrams for the D9400 (all I can find) show the P003/J003 jumper just behind the non-VGA connector, but it is not present on the D9800.

The D9200 had a ribbon cable on that input board that went to either a connector labeled VGA or a connector next to it labeled CGA/EGA. You moved it to whichever you were using. The pins that older monitors used were the CGA/EGA pins, and the other connector was the VGA.




Find a lamp or something and get those pics...
 
D9800 direct to JAMMA video

Hi, back again... been busy!!

Finally, a picture. Basically, connecting the JAMMA video to the 6 leftmost connector pins above the VGA connector gives some kind of video mixed in with the NO SIGNAL message, but no game image.

Am I missing an additional connector on the rightmost three pins?

Any ideas are greatly appreciated!

Thanks
