I am stumped by this problem I am having with the Rev 1.01B (MD) 60% Hacker layout board that I built a while back. The space bar has never worked properly, and I have discovered recently that the entire bottom row does not work, including the last key on the right on row 4. I can upload new bins to it fine, but nothing is working down there no matter what I do. I tested with a multimeter and it looks like everything is working as it should at the switches, etc. Is there something I am missing?
