This hopefully is a easy one. I'm repairing some trace damage that was done on this board when the pia was removed at U4. Almost all the damaged traces were obvious other than one, pin 40. I can't tell if it had no connection to the pad or not. The schematic sheet 1 has it labeled "sound busy" and references it to sheet 3 where I don't see it at all which leads me to believe it may not be used.

So before I solder in a new sip socket I'm hoping someone who has a spare board laying around could take a look and verify for me if there's a connection to it or not. One thing, there is a thru hole right next to pin 40 but it doesn't look to me as they were connected but I'm not 100% sure about that.

Thanks!

I'm not sure as to what you mean by it should be connected in some way to pin 40 of U5 for instance? I don't see where the trace was pulled off the board at pin 40 on either side of the board. Any way to get a picture?

Thanks all. I just needed to know if it had a trace missing or not since the schematics wern't 100% clear. And yes, I agree especially these 40 pin chips should be socketed.
