Success!
The procedure was fairly easy. (But, jeesh, there are a lot of screws to unscrew and an awful lot of PCB plugs to unplug).
The only issues I had were:
1) I lost first few screws in the body of the keyboard when removing them from the "windows" in the back. Since I don't have a magnetic screwdriver, I ended up laying on my back on the floor and unscrewing the rest of them in such a way that if they were to fall, the would fall out of the hole. This worked, but I can now hear the screws I lost inside the body of the keyboard when I move it around.
2) I had trouble getting the solder to lay flat on the PCB. It had a tendency to bead up and required a lot of "smearing" to get it to touch the contacts.
But, other than that, no issues.
Thanks for your help!
