So I bought one of steve23's boards he had on ebay. This was a Double Dragon that says that it is locked in test mode.

Anyway I don't know it this is a real DD or a pirate, but I need to know the pinout, since I assume it is not JAMMA.

I will post a photo later.

Does anyone know the pinout? Where I can get an adapter?
 
Thanks Mike,

I plugged it in to my JAMMA cabinet, and it makes it to the memory test with all roms OK and freezes there.

Anyone happen to know the dip switch settings? Is there a freeze video switch like on Galaga?

It's JAMMA. I just fixed 2 of them this week. You can find the entries on my repair logs site.

Set DIP 7/8 on both switch banks to ON. Set the rest to OFF. That will set it for upright cab and free play. It's an odd game in that you have to have a credit on it for it to play in free play.

Here's a pic of a real board:

I am having a similar problem with the Double Dragon machine, and you seem to be the expert here.. But in my case, the machine will not coin up. I put a coin in, no credit, i hit the credit button, no credit, i put the game in free play and hitP1 or P2, nothing. Can you tell me what other trouble shooting items i should perform...i would really appreciate your help

Trace back from JAMMA connector the not working inputs.Anyway, the problem lies in the 74LS244s or the custom TJR-001 custom resistor networks, they are both near the JAMMA edge .
