Hi,
I don't have the Popeye. I have spoken to 3 or 4 people in the UK who remember playing the Atari version cabinet so it DID exist.
The only Atari cabs I have seen in this shape in real life are: Millipede and Time Pilot. If you look at the Atari Liberator manual you will see a diagram that shows this cabinet for this game also - no one has ever seen one though.
I had 2 Euro Millipedes that were missing various parts and sold them on. I do have a complete working Time Pilot.
Gravitar is a different cabinet shape for the Euro versions. This shape was for the following games: Gravitar, Black Widow, Dig Dug, Kangaroo, Fast Freddie. I have ALL of them
I would love an Atari Popeye!!!
