Just picked up a Xenon with a bad MPU board.
I got a replacement board that tests good and works.
However, I am not sure about all the jumper issues with the ROM chips.
In the photo below my broken board is on the right and new replacement board is on the left.
I have already taken my two ROM chips out and moved them over to the new board on left.
However when I put it in my Xenon I get no green light at all on the board.
Do I need to adjust some jumpers or am I missing something else all together?
I can take closer or better photos as well if that will help determine what is wrong.

I put my U1 and U2 chips back in the original boards so I can ask John the easiest way to make it work without having to re jumper the board.
Does he have a Pinside Account or is it easier to go through his web page. (I have not visited it yet, but will soon).
Just for fun here are both boards with everything back in place.
I had only moved U1 and U2 over as I thought those were the only two Game Roms. (I am a System 35 noob).

Looks like John sells 2732's
Here are a couple of close up photos in case someone can tell if this new board is jumpered for the ones I can add to cart from his site.

Quoted from kursiv:

With new ROMs you still need to change the jumpers.

You are correct.
I finally have this all straightened out.
Got a quick education on Stern and Bally system 35's.
