I have no idea on this chip.

However, it would be cool if it came from a Bar Car (aka, Lounge Car) that existed on some trains back in the day. I don't think they exist any more.

Hop on a commuter train home after a hard day at the office. Join your buddies for a drink(s) and some poker on the ride home. The only downside would be if you're getting some hot hands, but it's your stop to get off the train!
