I don't see a fuse unless it's under the sheetmetal cover over the
ports, which it appears I can't remove without desoldering retention

I wouldn't have thought to look for such a thing though. I had no idea
PS/2 ports might be fused. (Not a bad idea, as electrically fragile as
they've historically been.) Thanks for the information.
