Hello, I have working moon patrol by williams. I recently bought the jamma 19-1 horizotal multi board for it. Also the 22-28 pin adaptor with power supply.

See picture attached of the set up - it plugs in and fits well.

I turn it on and all I get is a purplish blank screen?

Has anyone dealt with this before or know how to get to run?

thanks

Mark

Are you sure that's really a Moon Patrol to Jamma adapter? I wasn't aware such a thing existed in premade form. I mean, it would have very limited use, since Moon Patrol only has a two way joystick.

Is that Moon Patrol laying on it's side? J/K.

Check the power to the JAMMA side of the adapter. Normally those knockoff boards have an LED or two that indicate proper operation.

Ian I never thought about that - Your right there is no way this board could work for this cabinet with a 2 way joystick. I would have to install a 4-way and rewire everything.
Dam...

I guess there is no way of making this a multi-game unit without a new harness and joystick huh??
 
Not sure if this is it or not:

You may have already done this, but did you check switch #2?

It selects the different monitor types CGA or VGA...

Oh, and nice Avatar ;)

That's why I'm curious about that adapter. Where did you get it? As far as I can remember, Moon Patrol is a unique pinout. I find it hard to believe someone would go to all the trouble of mass producing an adapter to cram a Jamma board into a Moon Patrol, especially since so few games would be playable in one.

Does the adapter have any markings on it? A part number?

One only hopes that if it's not the right adapter, that you didn't damage the Jamma board by routing voltages where they're not supposed to go.

You could probably install a 4 way stick into Moon Patrol, hook it up to the existing wiring for left/right, and run two wires separately for the up and down movements. Then build a simple adapter board to go from Moon Patrol to Jamma, and add in the two new wires for up and down. That would be by far the easiest, and wouldn't require rewiring the whole cabinet. Also, you could still switch back to Moon Patrol.

The only thing you might have problems with is mounting the new joystick onto that panel. I don't remember what the Moon Patrol stick looks like underneath, but chances are the mounting holes are different.

I will try switch #2 when I get home thanks Gackattach - Nice eye candy huh!

Ian -if you want I can send you more of the pics I have to your email - the quality of the image is not good on this site.

I will look for a model number when I get home- maybe there is a way around this.

Thanks

you can take a 10 dollar jamma harness buy 3 bucks worth of small alligator clips, and put clips on the jamma wires.

then you can piggy back the jamma harness into the existing cabinet without affecting the original IREM harness. (being sure to unplug the moon patrol board when you plug in the jamma board.)

it's a whole lot simpler and less trouble. did that connector cost more than the whole multi-board? ;)

but with the 2way sticks, i believe that limits you to playing just mario and joust doesn't it?

You and I have vastly different definitions of "simple". Building an adapter board would be a heck of a lot cleaner and far cheaper, not to mention easier than having to install piles of alligator clips and routing wires all through the cabinet.

Have you ever actually tried what you are proposing? Putting alligator clips onto switch contacts can't possibly stay together - they'd pop right off with a little vibration.

Not to mention, now you have a whole separate harness in the game, it would be a complicated nightmare.

But still, I would like to know more about that adapter board, and where he got it. I don't think it's meant for Moon Patrol. Depending on what it's supposed to be used for, he may have fried his multi board.

-Ian
 
yes I do like the alligator clip method actually and have used it with dedicated joust and robotron, on temporary basis.
because most jamma boards are going to be impermanent, it seems easy to take 10 minutes and piggyback without getting out the soldering iron and wire cutters.....

getting ready to put one back in the robotron that i sold because friend wants to play smash TV. makes a simple non-intrusive way to use MAME on a real cab without modifying anything. just thinking outside the box...no right or wrong answers are there?

good point on the subject of frying the board. first 48-1 i got, was plugged in backwards to a cheap jamma harness. IMMEDIATELY ruined it. doh.

Moon Patrol actually uses the IREM pinout (minus up/down). Motorace USA also uses the same pinout (another IREM game licensed by Williams), so it's not completely unique. I think most of the rest of the IREM pinout games (10 Yard Fight, Kung Fu Master, Kid Nikki, etc) use up/down too, but the rest of the pinout is the same. I don't know if anyone makes an IREM cabinet JAMMA adapter though, couldn't find one online.
As to the joystick, it's probably not gonna be a simple swap for a 4-way either. Usually 2-way sticks have a narrower slot than a full circle that's used for a 4-way. I'm not 100% sure Moon Patrol is this way (I think it is), but I know other Williams 2-way games are (Joust, Defender, Stargate).
 
I did try switch #2 - it didnt change anything GackAttach - was worth a try

Ian - I looks like by adaptor was ment for Ms Pac man P/N- JB-JAM2PAC

This is the discription of the Multi-Board off the Jamma website below:

Item Description:

This single PCB contains 19 of the most popular classic Williams and Nintendo horizontal (displayed) arcade games ever! Each game has its original dip switches, which are adjusted through the built-in software menu. Another great feature is 'High Score' save, which will save the top score...even after the power is turned off! This is a brand new board, which I have thoroughly inspected and tested to ensure it is 100% functioning. Unlike the 'Vertical xx-in-1 Multigame boards, the 19-in-1 has many 2 player 'Head-to-Head' games for simultaneous action!

The board was $100 and the adaptor was $15

I have to look at the pin assignments of both The moon patrol board and the jamma board to see how close they are to at least putting a picture on the screen - then figuring out the controls shouldnt be that bad- right?

Does anyone know of an adaptor that will work for what I am trying to do?

thanks for all your input

Well, hopefully you didn't blow anything on the 19-in-1 or your cabinet. You can't just use any adapter that fits ;) Like I said in my other post, I couldn't find any IREM pinout to JAMMA cabinet adapters...you'll probably have to make your own. It's not actually that hard.
 
Ah hah! The truth comes out! It's the wrong adapter :)

*Fortunately* the kind of adapter you have is meant to be powered from an external power supply (since Pac-Man doesn't have a DC power supply), so most of the voltages should be unconnected. You *may* have escaped without damaging your board.

The only point I see that may be a problem is that 12v would have been routed to player 1's up direction. Hopefully there wasn't a ground connected somehow, otherwise you'll have blown up that input.

Make up a (proper) adapter, and you should be able to play that board in that cabinet, you'll have to do something about the joystick though. You may or may not be able to easily install a 4 way stick in that cabinet without having to drill out the hole in the panel, etc.

Also, remember, this is Moon Patrol, so the picture you get on the screen is probably going to be too wide. Those monitors shipped from the factory with some component changes to stretch the Moon Patrol picture to fill the tube, you'll have to swap out a cap to bring the picture back narrower. It might not be a big problem, you might just be able to adjust it narrow enough to fit. But... when you get the game working, it's something to keep in mind.

-Ian
 
yeah I see what you mean - its backwards.

I need to find or make an adaptor that is 44 pin male to 56 pin female
then rig a 4-way joy and still have to worry about if the screen image will adjust right.

dam... not as easy as I thought.
