No problemo.

I believe so.  Mine is a WG25K7191 and the wiring went:

Monitor wire => VGA B-O wire
Red => Red
Green => Green
Blue => Blue
Black => Ground bundle
2 Browns (Composite synch) => both the H and V sync

So my guess is that yours would be the same, with the 2 whites as your sync cables.  Not sure about the brown - are you sure it's not just a dirty blue?  :)

If your wiring is like mine, the monitor wire set we're talking about will terminate in a white clip, which then joins into the primary JAMMA harness.  If so, cut off the wires a little before the white clip, in case you change your mind and want to reconnect it all later.  If not (white clip), then just cut them anywhere that leaves you some wire to work with on both sides.  Next, strip the monitor wires and connect them to the appropriate VGA B-O wires using your favorite wire connectors.  (Or if you're more wire savvy than me, you may even be able to find a matching wire clip to connect the VGA B-O cable into and which would allow you to plug directly into the monitor cable clip and avoid cutting your wires)

It is my understanding that the WG monitors do not need a video amp with the AVGA - mine didn't - so you shouldn't need to worry about that.

If you decide to do this, PLEASE confirm my wiring assumptions first.  I'm definitely not an expert at this!  I did a quick search for you, but couldn't find a wiring diagram.  I'd bet that Ken Layton or one of the other video gurus would be able to verify if you post this specific question in the Video forum.

Thanks again Chris.  Looks like I did find the wires you are talking about  :applaud:  One problem solved.  However, I'm still a little confused with the wire cutting you explained.  I am really a visual person so sometimes it's hard for me to follow instructions without a PIC.  If I understand you correctly,

I am going to cut both B-O set of wires from my monitor?  Which means coming from my monitor board (PIC1) to my Jamma harness (PIC2).  Both sides will have to be cut?

If so, I'm not clear what I'm connecting both sides of the B-O wires to.  I thought I would have to leave the wires on the monitor board alone (PIC1) cause it's plugged into the monitor and then I would cut the B-O wires going into the Jamma harness only (PIC2) so that end can be plugged into the AVGA.  I hope I'm not confusing you now  :dizzy:

If for some reason this way doesn't work out for me.  Can I use the JPAC and just use the existing Jamma harness and hook up the new CP with the existing Jamma wires?  It's not my preferred way of doing things but the old CP that came with the arcade did work and I could just route the wires from the old CP to my new one.  It may take a lot of time, but at least it should work easily with the JPAC and AVGA.  But before I do that I would still like to use a separate encoder so I have more control over my bottons etc. and I can use a solderless encoder.  What encoder do you use?  I would like to get the LED KeyWiz for some cool lighting effects.  Oh well, first things first... figuring out this damn monitor problem.  Thanks again.

Chris G:

Just visualize that you are trying to have one continuous set of wires going from your monitor to your video card.  Let's see if I can explain this better.

If you were to buy the VGA B-O cable, one end plugs directly into your AVGA.  Easy.  The other end is a set of pre-stripped, labeled wires, as I've described previously.  Let's call that "A".

Then you have a wire set, which you've identified, coming from your monitor.  You would leave the end plugged into the monitor alone, follow the wires down a ways (let's say 6 inches), cut them off, and strip them.  Let's call that "B".

Now you just need to connect A to B using some wire connectors.  Done deal.

Does that make sense?  You are only making one cut.  The rest of the JAMMA harness does not come into play at all.  If my stuff wasn't all bundled and taped, I would take some pictures for you.

You would probably do just fine going with the JPAC too.  And maybe that's the better route for you.  I don't have one, but if I understand correctly, you just plug the whole JAMMA harness right into it and away you go - the monitor and controls are all connected.  The JPAC also has some additional inputs if you want more than 3 buttons per player.

urbecrisch:

It's crystal clear now thanks!  I'm not sure what I want to do.  I'm planning on a huge CP with 2 player joys, 6 buttons ea., usb trackball, ps2/spinner, and possibly some admin buttons.  Using the JPAC I would have to figure out how to connect everything together.  Also the JPAC is a little pricey and if I didn't need it I could use the dough for the LED Keywiz or something.

So when you used the AVGA to hook up your monitor was there any problem with the picture of the monitor? 
Everything worked out well with your PC running Mame and the monitor picture?
What encoder do you use and how old is your monitor?
CPU specs?
How do I get to the monitor settings if I don't use the Jamma harness?  There's a pushbutton on the inside of the CAB that is the monitor setup, settings, etc.  Where does that plug into when using an encoder?

My concern is if I do something stupid and then I will lose the monitor picture or the monitor all of a sudden becomes distorted or something. 

Oh, one more thing.
If I disconnect the Jamma harness, will I lose all power to my coin mecs?  I really want to use them cause it looks so cool.  Maybe I could use the 5v power from my PC power supply for the coin mec lights.  My CAB is really a 4 player conversion so I don't need all four coin slots.

Chris G:

Gonna do a machine gun response this time:

No problems with the picture that weren't there before.

Yes, everything worked out well.

I have a mini-pac, which was a mistake because my trackball and spinner are USB.

The sticker on my monitor shows June 1990.

My CPU is an AMD Athlon 64 3500+ 2.2GHz.

Sounds like your monitor is more advanced than mine.  Mine simply has manual dial controls for the horiz/vert size&position, etc.  which I mounted in a place I could get at without having to open the cab.

You shouldn't have to do anything that can't be undone.  That's why I suggested cutting the wire (if you go that route) in a way that you could reconnect it if you change your mind.  Can't provide you any insurance against "doing something stupid", though.   ;)

The power to the coin mechs did run through the JAMMA harness on mine.  I simply rewired them to the monitor power supply.  I'm sure it would work to use your PC power supply as well.
