Not sure what PCB this is.
Wanted to make a Jamma adaptor to test it.
Anyone help me out with this?

You're best bet (if you don't have one), is to find someone local with an EPROM burner and do a ROMIdent on one of the EPROMs.
 
Not universal....

It looks familiar, but I can't place it... I know I've made and adapter with power both on the ends and in the middle like that.

Sell it to me cheap and I'll tell you what it is once I fix it :)

The confusing thing is that it has 7x 2125s for one sprite plane, but also has the white ceramic RAM for another plane, and the gfx ROMs in the lower corner for the background. The way the design is partitioned, the original was likely multiple boards -- you can see the sound board partitioned out in the upper right corner.

Trying to find out what board it is so that I can test it.
So it might be functional, just need to see what it is.
Thanks for the input though.
