I killed the keyboard port on my main desktop machine today.

Whoever "designed" my IcyBox external hard disk box decided that it would be a good idea to use a PS/2 plug as the power connector, stupid.

I had never noticed that it used a PS/2 plug and today accidentally plugged it into my keyboard port, stupid.

Clearly the voltages on the hard disk PSU disagreed with the PS/2 port, even though it was only connected for a second or so, as it doesn't work any more.

Unfortunately my preferred keyboard is a PS/2 one, so it looks like I'll be buying a new motherboard

For the moment I'm using my Mac keyboard.
