What kind of System 16 hardware is this?!

Check out this weird motherboard and ROM board. Any idea what this is?

I think it is an early System 16 PCB, I have a similar one with Fantasy Zone on it. The more common S16 PCBs have revision a on them which means they revised it from this. You can see that it has had the suicide battery changed, don't think I would rest it on the components though, personally

It's the second revision of System 16A, only compatible with S16A romsets.
