  This was a major design flaw in the
 Pole Position arcade PCB's, someone positioned the backup
 battery at the top center of the board when it was mounted
 sideways on the inside side wall of the cabinets and when
 the batteries died, they died a horrific messy death,
 usually taking out a 3 square inch of the PCB traces with
 them.
  
Don't remind me...
And it was many more than just Pole Position. There were *lots* of 80's video games,
as well as pinball machines that suffer from the same fate. I've spent more hours
repairing battery damaged boards than I care to think about.
