Actually that may be one of the few unconverted Pole Positions left over from the Phillip Morris lawsuit.
About a year after Pole Position was on the market, Phillip Morris sued Atari for the unauthorized use of their Marlboro trademarks and advertising in the Pole Position machine. I still remember the overnighted legal letter and free replacement rom chips we got. The letter stated that Atari had 'mistakenly' put Marlboro graphics in the game play. Phillip Morris was concerned it would also be contstrued as selling cigarettes to minors (yeh right like they would really be concerned if the kids were smoking Marlboros). So Atari sent out free replacement rom chips for every Pole Position that had been registered with Atari by filling out the Warranty Cards when the game was purchased new from a distributor. There was a time limit on when these chips had to be installed and the old "infringing" chips returned (at no charge) to the Atari factory.
There was a legal piece of paper we all had to sign. The serial number of the machine done, the name of the tech performing the work, date the work was done, signature of the tech, and signature of the company officer/supervisor/owner all had to be on the document. The document was to be returned along with all the old 'infringing' game roms.
It's possible a few Pole Positions escaped Atari's and Phillip Morris' eyes.
