I don't ever remember seeing this in the arcade when I was a kid. Too bad. Essentially a normal Vectrex home unit inside an arcade cabinet. The coin slot activated a timer that let you play Minesweeper (the Vectrex built in game) with infinite lives until the time ran out. You could put in more money to extend your time. The inside is pretty much a normal Vectrex (case and all,) the joystick is even the home console controller mounted to the cabinet! Very rare and hard to find, I imagine that these things are probably worth a lot of money now.
