Quoted from LTG:
Similar to WOZ. It's basically a Williams pin and they snuck a motherboard and hard drive in there.
If you can do basic repairs. You'll be fine. And so far there haven't been many issues with the number of Hobbits going out.
And I would love to assist you, should the need arrive.

Thanks Lloyd. With WOZ the only thing that intimidated me were the upper playfields, so with Hobbit not having them, I think I should be ok.
