Hi,
What a fantastic community you all have created! I just got lucky and acquired a Bally Manufacturing Corporation Draw Poker Machine. V1336-1 / 42
It's a four-board version. I hear these are great

So my first question is, should I clean the dust from the machine? It's gross, but it's working perfectly! Well, until I tried to remove the boards, and some cable came loose. I pushed on some connectors and it's back to functioning.
What would you do?
Thanks,
Rich
P.S. I love it because it's all $.25 coins.
And does anyone know what these numbers mean behind the top glass?
