ChadTower:
CPU board with all new sockets except the ram which already had replacement sockets, a new male 40 pin interconnect, new sound header since I'm having issues there, and the battery holder moved off board.
I tried to pull the sound PIA to socket it but couldn't get it out without damaging it so I just resoldered the whole thing. It's worth a shot as I don't have any spares.

Popped the power board back in minus that missing disc cap... figured it was broken before, can't hurt anything now.

Put a new disc cap in and the one electrolytic that I didn't have at the time... one of the 100uf 150v caps.
I'm holding out mild hope that when I put all these back in the sound will work properly. Mild hope.
Jeff AMN:
Good to see that you're keeping on track with this, Chad. Keep the pics and info coming.
ChadTower:
Put the boards all back in... nothing fried. That's good. Now it only boots into audit mode. It did that intermittently before. This is probably either an error in the battery holder hack I did or the 5101 RAM crapped out. I think that's one of the socketed chips so I'll just have to order a couple and see if that works.
Sound test still fails exactly the same way.
ChadTower:
Booting to attract now... had to go into audit mode and cycle through the settings and force it to write to memory. I couldn't do that earlier because my son took the key out of the coin door and put it someplace random. Had to wait for him to get home.
For a change of pace I'm going to start on the top of the playfield now. I'm a bit burned out on these boards.
