Some motherboards will fry if you try and hot swap a PS2 mouse. Certainly the
keyboard/mouse chips will. Specifically some of the 350 servies IBM's will, though
they claim to be 'hot swapable'.
Some serial to ps2 converters don't actually run all the wires correctly, and
sometimes you have to have a specific adaptor for that brand (I don't know why, they
are just wires).

I like these mice.
