hello all, long time lurker from Denmark, i just wanted to add this tidbit about the museum, the founders were a father and son and some of their friends, they have an gigantic collection, many of their machines are from funfairs, and a local amusement park...
I've been and seen their collection a couple of times, its fantastic to see.
They even have a Dragons Lair machine on display

(and as far as i can remember they have amoungst many others a working g-loc and r360 but not on display)
