Can someone identify this PCB?

This PCB was in a machine that I just picked up in a package deal. There are no identifying markings on it except for "greenbrier Marketing Intl" on the adapter. Of the 5 cabinets I picked up, they all have identical power supplies and then have an adapter made depending on the PCB they used. The lot came with 4 PCB's, a Ladybug, a PCB labeled Moon Cresta (bootleg), one that had Space Battle instruction card and chips labeled "SB", and this double stack.

It doesn't appear any of the power supplies work, so I can't test any of these at the moment. It is a two stack PCB. Any guesses?

Thanks! You can tell just by looking at it? I have much to learn.

Yes, by recognizing some key components and the board layout. This is an interesting bootleg though... it has power supply components to convert AC to DC, like Pac-Man and Galaxian boards. From the pinout, it appears that it was designed to plug right into a Galaxian machine (minus the Li'l Green Giant adapter).

Most of the Phoenix boards I've seen (bootleg included) have an 18/36 pin connector. This one has a 22/44 pin, so I'm not sure what the pinout should be. I'd like to see if I can test this PCB, but I'd need the proper pinout to make a new harness. If this turns AC to DC, I bet that's why I couldn't get any voltage readings off the old power supply. All 5 of these goofy generic cabinets I just picked up just have step down transformers in them. In my stupidity I assumed AC went in and DC came out. I bet checking again with my meter on AC might yield different results.
 
Yes, like I was saying, that board has a Galaxian pinout, so treat it like a Galaxian. Not sure where they mapped the shield button, but it should be simple to figure out.
 
I wonder if these bootleg Phoenix boards used the same music chip as the factory boards? Or was that part reverse engineered on the boots?

Those music chips are getting near to impossible to find.
 
never mind... They used the same chip as the real boards. :(

They use the same chip (so yes, cheap bootleg boards are a good source for them).
