Looking for optical grid mouse pad

[Camiel Vanderhoeven]

It is a mouse systems mouse, model M4Q, and it has the two holes (one red light, one infrared), so I'll need the blue-and-black grid. I've hopefully bought a correct one off eBay, just waiting for it to arrive.

    There's a blue-and-black grid, and an all-black grid, at least with Sun
    mice. Mice that work on one won't work on the other. At least with the
    blue-and-black grid, spacing didn't seem to matter -- I've got three sizes
    of spacing, all three work with the mice that support it.
    
    Not sure if it applies to your situation, but the Mouse Systems mice with
    two holes, one emitting red light, work with the blue-and-black pads, and
    the newer Sun mice with a single hole works on the black grid. The
    blue-and-black grid looks metallic blue until you take a close look with a
    lighted magnifier.
    
    Thanks,
