Hello, I really hope someone can help me out. I'm brand new to anything related to real arcade equipment (I've been doing MAME for years).
So I recently bought a jamma supergun from Neotropolis on ebay. I then bought 3 jamma boards: CarnEvil and Invasion: The Abductors from ebay, and an aftermarket SFII:CE board from Quarterarcade.com. All of them sold as 100% working. I can't get a single one to work.
First, Carnevil:
When I power it on, I get no image and the only sound I get is a steady pulsing sound.
The LEDs indicate:
disk drive not in use
waiting for disk drive
exception occurring
sound reading from instructions
no -5vdc power
The rest indicate normal operation. Now with the hard drive, I've tried 5 different hard drives, and on all of them I first imaged one version of the mame chd, then tried the other. The only difference between any of them were some of them showed disk drive not in use, some showed disk drive locked up.
Now for Invasion:
Same thing. Power it on, no image, the pulsing sounds more in rhythm with a heart beat. The LEDs are all lit up, indicating both the game code and the sound are locked up.
Street Fighter II: Champion Edition (aftermarket board):
This one has no sound, but I do get a garbled image. On my standard CRT, the image is scrolling vertically with jumbled red, blue, and white graphics. On my HDTV, through either composite or S-Video, the image does NOT scroll vertically, and the colors are gone, just black and white jumble.
Does anybody have any ideas? Its all starting to drive me nuts!

Is there a way to adjust your +5 voltage?
-
Before you do anything else -- Check all of your voltages.

No idea. Here's a picture.

What exactly would I be looking for?

You need to verify that your input voltages are correct. There should be a +5V, +12V and -5V.

You should also post some pics of your set up and the boards that you are connecting to. Are extra power cables required for your hard drive games ?
-
and I dont know if CarnEvil is the same as KI/KI2 but in order to use any HD other then the OEM drive, you need a bootrom
-
The supply shown only has 5V and 12V. Looks fairly puny 25W.
Have to agree with Cheffo and RayB the heart of your problem maybe your power supply.
Just for your info
Happs recommends the following power supply for Carnevil
CARNEVIL MIDWAY POWER SUPPLY 5V@16A, 12V@6A, -5V@.5A, -12V@.5A
Now you probably do not need the -12V but the supply provides much more power than your power brick.
-
Thanks for the replies everybody, I'll do some voltage checks and get back to you.

Ok so on the Jamma harness, both +5 read +5.21v, and the +12 reads +12.02v. And the -5v is not wired.

QA sold the SF as tested/working?
Another trick is cleaning the edge traces with a pink eraser. (You'd be surprised). Check all cables and chips are firmly seated.
Your voltage seems good, though on the higher end of tolerance.
-
I think both Invasion and CarnEvil require -5V, but am not 100% sure.

SF was said to be working. I'll definitely try the eraser and the chips when I get home. Thanks!

Figures.. how hard would it be to wire in -5v? I'd also need a new power supply, right?

All right, I've decided to sell this Supergun.
After looking at how it's wired, it's primarily wired for Neo Geo, which is fine, but the games I want to play on it don't work. I opened it up to see if I could rewire it, but all the connections are neatly hot-glued. Also, the whole reason I spent this kind of money on it was to avoid doing any wiring work myself. Anybody know anyone interested in a Neo Geo supergun?
Here's the original auction:
