Thanks for that, Nino. I only started playing pinball when I was at uni and by then we were into the SS era, so I barely know anything about EMs. It is helpful to have some sort of list to refer to in case a project opportunity pops up.
I did live in a house with a pinball machine for a couple of years - I am guessing it was an EM - but I can't remember which title it was. It was probably a Gottlieb, though.
