A-PLAN Pinouts:

A-PLAN is a gambling game (slot machine)

These are the pins I have figured out:
- The game seems to be perfectly playable in this configureation, however,
I do not know if there are more pins to perform more tasks in the game.
There are still quite a few un-connected pins which I can not identify.

When you hold the PCB with the edge-connector away from you, and chips are facing UP, pin 1 is on your left.
The bottom pin 1 is directly below the top pin 1.

There is also a small edge connector on the side of the PCB.  
Pin 1 is closest to the main edge connector.
