There's another
Galaxian at sort of Nostalgia museum in Japan (not the UGSF one, different joystick). Another one aside from the UGSF one, but I'm not entirely sure of its location.
There was an upright Puckman at the Hatoya Game Center as of 2003 in Japan.
There's a Namco cab converted to Ring King in the movie Big

(no clue if it still exists, but in the U.S.)
Arch here has a
Rally-X. There's another one somewhere in the U.S. There's at least one more converted to Puck-Man in another museum type setup in Japan. Sounds like there may be yet another one in the UK


Dazza1 has (had?) a
Xevious in the UK. White T-moulding.

There's a
Mappy in an abandoned hotel in Japan. Appears to have orange/chrome molding not unlike Nichibutsu cabinets.

I heard of another upright
Galaga in Florida, U.S.A. somewhere. There's a pic of one that keeps making the rounds on the internet with a black coin door and a screenshot in place of the instruction card. No idea of the origin of this/where it's located.
