Hello all,
I am working on a cabinet and I want to hook up a Nintendo Monitor. My question is:
Since the Monitor is running at 100v and the light I suppose. Can I wire in a newer power supply directly from the transformer to power a Jamma board?
What happens if you wire this monitor in to a standard power Block setup?
 
well you don't want to send the monitor 120volts. When I picked up that galaga 88 cab a few months back it had a 20ev, so there is a way to do it.

As far as running a switcher in the cab for jamma? You can run ac wiring from a power distribution block at 120v to the switcher, and figure out a way to get the 20ez to be stepped down or modified I am sure.

I was hoping I could come straight off of the Nintendo transformer and in to the switcher.
 
have you measured the voltages coming out of said transformer?

Not just yet. I am (assuming) that it is 100v since it goes to an A/C plug that runs the monitor and light. At the same time it branches in to the Nintendo power supply.
 
just tap the primary side of the iso instead of the secondary and you'll still be getting your 120v.
its not a good idea to power the switcher from the isolated line anyway -it just puts more of a load on the iso that it may or may not be able to handle.

I was thinking that as well. Has anyone ran this monitor off of a Jamma Harness? I am now wondering about the sync being a problem. I know Tron said he had a Galaga with this monitor, but I want to be sure how to wire it.
 
standard nintendo sync is composite negative, same as jamma.
I have a galags cab that i use to test my nintendo pcbs in.
The biggest issue besides the 100v iso is the inverted video that nintendo used. The monitor should have a little inverter board on it, you'd just use the inverted out from the inverter board on the monitor to run a standard jamma game.

Cool thanks.
I will run the switcher 120v direct. then cap off the other outputs that went to the old power supply. It just seems like the switcher is always coming off of the transformers.

The wiring coming off of the Nintendo are Brown/Yellow/Blue/Red/Green/Orange
And of course the Standard Jamma is R/G/B/BK/W
So why the extra wire? Is that to invert?
Which wire goes where other than the matches of course.
 
I am going to jump over to the Montor section before I get Flamed...
 
Nope

and the extra wire that you are talking about is ground.

Thanks.
Red = Red
Blue = Blue
Green = Green
Brown = Black
Yellow = White
Orange goese to ground.
Is this right?

and what about the other two connectors? Black and White, and Red and White.
 
here's the monitor section from the pc-10 dual monitor manual. Dave can tell you better than i if that's correct. Looks odd, but it is nintendo.

Not even close

Brown = Green
Red = Red
Orange = Blue
Yellow = Ground
Green = Ground
Blue = Sync

Black and White? (You mean the AC connector?)
Red and White = Speaker

OK. thank you sir.
The Black and White don't seem heavy enough for A/C. Also the main A/C plug is soldered in at the main board with a fuse and plugs in to the 100v outlet.
