I've been able to identify most of the boards I recently picked up, but there are a few Im totally clueless on. Does anyone know what this one is? Big blue board that only has PCB-x and PCB-Y labeled. Thanks in advance for any help!
Yeah, it looks similar to a bootleg Galaga I recently worked on.
And I think it had 4 Z80s... the 4th was to replace one of the Namco customs, from what I read.
