A few weeks back, I spotted a pcb on ebay with a red Zacc serial number sticker and a Falcon logo on it.
My first thought was Crazy Kong, but this one was quite different from the well known versions.
The seller advertised it as a Scramble and sent me a Konami to jamma adapter also, but I was pretty sure, it will be something else.
Before I fired it up, I used romident and it turned out a Puckman/Hangly Man pcb.
I checked the pinouts and seemed like I can use my Crazy Kong adapter upside down.
Result:
There is no title on screen, just "Nittoh" which is the manufacturer of this board.
The maze is quite different from Pacman, there is a nice description on wikipedia with the other differences.
The major difference from the original Pac-Man game is that the first two boards and every even-numbered board after that are slightly altered versions of the original maze. The third board and every odd-numbered board after that are not mazes at all, but contain only the ghost house, the board's boundary outline, and the pills, arranged in straight vertical and horizontal lines. To access these levels, the player must eat four ghosts after eating a power pellet on level one. After that, every power pellet eaten turns the maze black until the power pellet wears off. And then the odd maze appears at level three. On these levels, in addition to the horizontal sideways left–right escape passage, there is also a vertical one connecting the top of the screen and the bottom, which the ghosts cannot enter. If the player moves Pac-Man to anywhere in this passage, and then pushes the joystick to the left or right and holds it; the Pac-Man will become stuck in that position, and the monsters cannot catch him, even if he is far enough out that they can touch him. But as releasing the joystick frees him, one cannot leave the game running with this method. Also, there are no walls anywhere in the maze, so Pac-Man can go anywhere, but the monsters are restricted by the walls depicted in the other levels.The pcb looks like this, unfortunately the "wakawaka" and the "pacman death" sounds are missing, if anybody has any idea, which chip is responsible for these, please help.
I'm pretty sure, this was the pcb, that Zaccaria used in dedicated Puckman cabs.
