Is it up to me, then?
So, around the time that I owned Big Ben and Magnatron, I also owned a third machine, all bought from Todd ("TNT amusements" in PA) and fixed up by myself and a good bud, bumbling in the dark as it were.
Unfortunately, its backglass had been shattered, so I reconstructed one out of plexiglass, with art featuring a certain P3 Scottish gal I liked at the time.

Now if you follow the theme of what the gal's wearing (or not wearing), well-sir, I think you might be able to guess my third game!
