How will I power this monitor?

[Kayden]

I have a Ninja Gaiden cabinet I'm looking to turn into a MAME cabinet, but I'm not sure what is safe to take out.

The power plug leads to this "dirty thingy"


The "dirty thingy" then connects to the "silver thingy" and, I think, the monitor


The "silver thingy" then connects to the logic board.


If I'm looking at this right, the power for the monitor goes off to the right along the bottom and the power to the board just goes right up the left side.

Can I take out the logic board and "silver thingy" have the monitor still work?

Any while I'm at it, what are the "dirty thingy" and "silver thingy" and what do they do?  I'm guessing the "silver thingy" is an AC/DC inverter and the "dirty thingy" is an ... inline power whatsits...  The tube takes strait AC?

The "silver thingy" is a switching power supply....pretty standard.
For a MAME machine you won't need it.

The "dirty thingy" is a transformer. (along with other essential parts on that same board)
LEAVE IT.
It provides isolated power to the monitor and it also provides power to your marquee light and such. (see the tag on the monitor power cord)

Remove the two wires leading over to the switching power supply and and be sure to either completely remove them from where they are tied into the rest of the wiring or cap them off so as not to have live AC flopping around in your cabinet.
OR - You could also potentially use those same AC wires to power the PC power supply if you so choose to.

Excellent, thanks.

So I take it that I can use the switching power supply for anything that needs 5/12v that my PC PSU wont handle?  Unlikely as that may be, it'll be nice to have something to play with.

[Kevin Mullins]

Sure....

You may want to take a look at the wiring to see how the coin door lights and such are wired before you yank too much out. (just a heads up if you want to use those lights)

is that a stargate cabinet?

[Kayden]

No, it's Ninja Gaiden.

[SirPeale]

No, it's Ninja Gaiden.

 

It's definitely some kind of Williams cab, but since I can't see the profile I can't tell you which one.

[Kayden]

   I take it stargate is a form factor.

Here's a front shot if it helps:

[SirPeale]

You have a converted cab.  It was either a Robotron: 2084 or a Joust in it's first life.  It was converted to a Ninja Gaiden once it stopped earning money. 

Interesting...there isn't an entry in the Wiki for conversion cabs.  This will have to be changed. 

[Kayden]

It's interesting you should say that.  There was a Joust instruction booklet and stickers in there when I opened it.

I was told that since NG was made in 1988 that this was a Jamma board.  Obviously, that doesn't change, but is there any issue with the monitor being older?

Then that's most likely what it was originally.

JAMMA is a standard setup that came about and replaced many of the older games and is commonly used to this day.

Nothing wrong with using that monitor..... a monitor is a monitor so to speak.
Heck, the older ones were the workhorses of the bunch, it's the newer ones that I always doubt.

[Kayden]

Hmmm.

If I remember correctly, I read that JAMMA boards are configured with a standard plug port to make connections easier, but it looks like the connections on my board are all individual wires, is that just the fallout of being a re-purposed cab?

[Kevin Mullins]

Not sure what you are looking at then .....
That single large green connector is the JAMMA connector.

And yes, they are designed and configured to have a common pinout to match many different "JAMMA" boards. So that for the majority of them it is plug-n-play. (there are a few exceptions, but understand the basics first)

Oh...  the green thing comes off?  I thought the green thing was part of the board.  I haven't got around to taking it apart yet.
