yes, and in asteroids deluxe the starting rock positions use this RNG to position themselves, so if yo usee the rocks bunched up, change the pokey :) I've seen it at least twice while doing repairs...

  Subject: VECTOR: Deluxe Pokey used as RNG??
       I just had to change the Pokey in my Asteroids Deluxe. Board is now working great. 
       Before the old pokey failed, I was getting some really weird symptoms from the board. New waves of rocks would start, with all rocks EXACTLY overlapping each other. Aside from this, the failing pokey had the board putting out some really weird random noise (to be expected). However, I did not expect to see the rocks overlapping and have no separation during new waves, or when they were hit. 
       I didn't know of any pokey's function to be used as a random number generator, am I wrong here? Or was the failing pokey also screwing up some stuff in the AVG or logic side? Anybody have any takes on this?
  Thanks,
  MK
