So I was down the front in Southend-On-Sea (in Essex, England, UK) last week and I spotted some cabs and bits in the Happidrome arcade (down towards the Kursaal end, opposite the public conveniences and the kiddies pavement fountainey thing):
Defender
Space Invaders
Track & Field (classic 3 button set-up)
Simpsons
Pac-Man
Addams family Pinball (x2)
Indiana Jones Pinball
...all in fairly good condition too so worth a pop-in if you find yourself in that part of the world....
