It's definetly a resistive DIP package...

Yes, probably used as a primitive protection scheme , it connects 
annunciator outputs to pushbuttons throuhg resistors thus sw was capable of 
detecting the chip, but also game controls were linked together... affecting 
position detection..

Thanks for hints
