RE: Deluxe Pokey used as RNG??

I had the exact same problem once with a _Centipede_ board: All the
mushrooms were lined up all along one edge of the screen, instead of filling
up the screen at random. Bad POKEY.

  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...

         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
