Re: Battlezone sound problems

I belive Radio shack has LM324s on the rack.

You should remove the 4066 from the circuit to prevent it from injecting noise. I don't recall seeing a case of a 4066 making noise as you describe.

I'm not familiar with BZ enough to know the sound circuit off the top of my head. Pokey, Engine rumble (noisy pot?).

Is it all sounds or just a given sound?

Ah reread your original post.

Given that you've lost all sounds it must be in the mixing/amp stages unless there is some sortta sound enable. Do all the sounds go thru the 4066?

  I don't have an oscilloscope. I think I'm gonna just close the switch manually by crossing the input/output pins. If that produces sound, I'll know that the 4066 is bad.

  I have the following parts to trade:

  AMD 2091 bit-slice processors, up to four in quantity
  2114 RAM, up to 13 in quantity
  4116 RAM, up to 24 in quantity
  Williams "Special Chips", up to two in quantity

  I also need 4 or more LM324s.
