The board is a much later revision according to my source, definitely the meatier CPS1 games of my collection.
Please excuse my haphazard installation of the spinner. Note that the spinner has a microswitch function as well by pressing it down. I was quite skeptic about that aspect of the control scheme as I needed to adopt a 2 finger 1 thumb hold on the spinner to make it work.
I was not wrong....
But I had an awesome time learning to play it.
