Fire up the heat gun and replace the entire SIMM socket assembly...

The first time I did heat gun desoldering, I lost a bunch of small surface mount components off of the patient. I shouldn't say lost, as I had possession of them, I just had no idea which ones went where.
We live and learn. Since then, I cover up nearby parts with modeling clay.
