High Score Saved Again

A little more love was given to the Pole Position II today.  I replaced the ghetto fabulous score saving cordless phone battery with a Dallas Semiconductor nonvolatile SRAM.  Now my dismal hi-scores will be saved for all posterity.

This chip replaces a socketed ram chip about three spots north of the old battery location.  Previously I was using a rechargeable battery to maintain the scores, but found it to be a bit unreliable.  This is a much better solution, and should last a good long time.
