I haven't had time to check my machine, but after looking at the schematics for a while I think the "sound enable" line must be stuck on (maybe a bad ls273 at M2). I'm also making an assumption that there is sound always coming from the pokey and it's just muted at the 4066 at L4. If someone has a chance, could you check if there is a signal coming from pin 37 of the pokey when the game is in attract mode. (or jump across pins 10 & 11 of L4, which would allow any sound to pass to the amplifier) -jeff -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of vernimark Sent: Sunday, October 10, 2004 7:37 PM To: [email protected] Subject: RE: VECTOR: Battlezone problems Jeff, what about your BZ?
