What have I done!

+1 on the voltage spike possibility

The PP pins send and receive 5v signals depending on the pin.

Or 3.3V for most modern cards and laptops.....

I remember when I could have popped over to PC world and picked one off the shelf but times seem to have changed.

Maplin still stock some but I'm not sure what bus types for and what voltage data levels.
