Hi, what is this board called? Where can i find a replacement? I think the one I have is bad.

ok but this is out of a ikari warriors cabinet, and that is a ikari warriors pcb, so i thought the first ikari warriors game was non jamma.

Am I wrong?

If in fact it is a jamma adapter, can i just buy any new jamma adaptor?
 
Why do you think it's bad... it looks like a JAMMA adapter, which is a pretty simple board... not much to go wrong besides burnt traces or connectors. And yeah, the first Ikari Warriors wasn't JAMMA, which is why it needs the JAMMA adapter. With the adapter, it can be used in a JAMMA cabinet.

I've got the same exact deal in my Ikari.

It looks like a jamma adapter (same number of pins), but its not. The pinout is SNK specific. The manual talks about it.

I actually lost some signals on my game for a few days (coin inputs) but I reseated that extender card and it worked again.

I have no idea what the purpose of this extender card is. Why doesn't everything go straight to the PCB?
 
yeah that is what im screaming, I mean if you loose or break this card, where the hell would you hunt a new one down? buy another dedicated original ikari cab? that is just crap.
 
I can't see the pic, is this the universal card as described in the manual? If so it is nothing but a pass through and should be easy to fix.

BTW, it looks like this was designed to make the machine easier to convert in the future...
 
Why do you think it is bad? I can tell from the pic that you don't have your joysticks hooked up to the pcb...
 
what this thing seems to do is takes a big harness and allows it to plug into a smaller edge on the pcb, the wide end had like 44 pins and the small end on the ikari pcb had much less.

It has a resistor on it so it must do something important. i am trying to rule everything out to why my cab isnt working, the monitor powers on but i get no picture on the screen, its just like a whitish purple.
 
Board

Do you have a Jamma board that you can plug directly in to the harness? Have you tested your voltages going to the PCB?
 
From looking at the manual posted earlier I wouldn't plug a Jamma board into the cab's wiring. There is a 56 pin connector but it is not a Jamma configuration.

Can you host the picture on this website by adding it as an attachment?

You said that it has a resistor, is it one resistor or a series of resistors, one for each circuit and possibly coupled with diodes?
 
That does look like a SNK to Jamma adaptor at first glance. But I think it is the Universal adaptor pictured on the last two pages of the Ikari Warriors manual. Power looks to be the same but the controls are different.

You can easily test this piece with a multimeter. Just test for resistance across each leg, from edge connector pin to edge connector pin. You should be able to see where each trace goes by looking at the board. What circuit is the diode in?

darer,

Let's back up a little bit. How did you determine that this board is the problem?

Have you done the basic first steps like:
1) Verify that the voltages (+5, +12, and sometimes -5) ON THE GAME PCB are good?
2) Replace the game PCBs with a known working set?
3) Taken your game PCB to someone's Ikari Warrior machine to verify they work?
4) Does the game play blind?
5) Did the game ever work? If so, how long ago did it stop working?

I only briefly glanced in the manual.... but I thought the "Universal" Adapter was more like the other one mrbill2084 posted.
But then again, maybe I should study the manual some more myself. :)

Seems like someone else had a post with this SNK to JAMMA looking pcb thingy just recently.

ok so i have a dynamo cab, at least that was the manual that was in the bottom, does this mean that I have jamma wiring in it? because I have the use the extender?

i thought the point of jamma(besides uniform wire colors and positions) was that it was a bigger edge with more contacts on the pcb.
