My Monday-night keyboard adventures took a wholly unexpected turn Tuesday. I had said that I was going to swap keyboards the next night, and I duly picked up a used but working model from the corporate parts locker. (I am one of the last people on earth using a PS/2 keyboard connector, it seems, so this won’t be missed, and yes, the sysadmin is aware of it.) But for the sheer hell of it, I decided to plug in my late, lamented IBM Model M, just to see what happened.
And the sucker worked perfectly, even on the keys that weren’t working before.
Conclusion: Despite my earlier diagnosis, something inside actually had gotten wet, and, in the manner of things gotten wet, dried out some time in the subsequent seven months.
Super Talent (!), the manufacturer of the keyboard gone bad, has since moved into products without moving parts. I’m not complaining, really: this particular keyboard was thrown in as a freebie when I had my current tower custom-built, and that was a good seven years ago.
