Slightly related but I once got a 'behind the scenes' of a bowling alley, I was amazed to see (not sure if still the case, could very well be) how 'analog' the whole machinery was, with a big wheel and lots of mechanical entrapments to pick/collect/replace pins. I think the technical constraints demanded a lot of ingenuity back then.

If I remember correctly they added digital score keeping as an afterthought using camera's (+ software + screens).
