Looking at the Amiga PCB Explorer site, I couldn't help but notice that the A1000 isn't there. Is there a place I can find PCB schematics for the A1000, specifically the daughterboard?

I need to repair a broken trace off a non-working daughterboard, specifically the one that goes to pin 19 on U6J.

I don't have a pic handy, so I took one from EzdineG's thread on installing a Kickstart adaptor. This is the trace I need to fix:

I've tried figuring out where it leads to, but have not succeeded.

Any help would be appreciated!

I traced that connection, and it goes to pin 9 on U6Q, which is one of the connectors to the motherboard. I'm not sure of the pin ordering on the connector, so it may not actually be called pin 9, but if you apply the pin ordering of the nearby chips, then it gives you a reference.
