The research document can be read here: Finding ScrollPoints in new condition is more uncommon, but not impossible. Various online sellers and auctions will generally have ScrollPoint mice available in bulk. This however is incorrect, all ScrollPoint mice use the same resistive mechanism and all cite the same patent. The first version of the standard three-button ScrollPoint mice were announced in around

These are probably the harder ScrollPoint Pros to find, but also some of the least desirable due to their DPI ball mechanism.

Most mice will have red sensor LEDs mmo09bo they are cheaper to manufacture and more responsive to the sensing IC. It appears there have been two manufacturers for the Slate Blue plastic bezels as the colour can vary from being more blue or purple.

The next important thing is that the Slate Blue ScrollPoints do have a slightly slower cursor seems to be firmware-related BUT they are able to work with transparent surfaces glass, clear plastic, etc. All proprietary software is property of IBM. The LED is mounted facing just behind the same– it can be swapped out for any desired colour.

Ideally it would be nice to have the transparency tracking features of Revision A, coupled with revision A’s more sensitive ScrollPoint, and revision B’s faster cursor sensitivity. A few reasons may be that 1 most people don’t like change, 2 the ScrollPoint performs too fast without drivers, 3 IBM didn’t push marketing or continue to really develop the product into the mainstream.

And finally you’ll need to cut a larger opening for the clear ‘window’ piece that allows blue illumination through. Make sure there mo09b no excess glue to make the buttons taller in height than they were originally: If you’re going to use a Lenovo board, be warned that some people have reported premature failure with them– most likely due to cold solder joints or prematurely failed capacitors.


Regardless, it does have a following of few who like the ergonomy and enhanced scrolling ability.

This really gives the ScrollPoint a unique colour and helps keep with the theme a lot better. Many used ScrollPoints will have little to no wear as they are generally not used in service extensively from users ultimately swapping them out for a wheel-based mouse; at least, this was common for a time when IBM bundled ScrollPoints with all of their computers such as IntelliStations but ended after a period due to customer disastisfaction.

Metallic Black Depth Metric: Install the latest Lenovo driver which I think makes Chrome see it as a standard wheeled device– since that’s all it has been programmed to see. They were paired with the earlier IBM wireless keyboard.

The original ScrollPoint mouse debuted in to combine the similar TrackPoint mechanism as found on the ThinkPads to replace a standard mouse wheel.

It is possible to ‘donate’ the rubber siding from the ball ScrollPoint Pro to the optical one, this does require some minor modifications however. If your ScrollPoint isn’t new and has a damaged rubber coating, just use a magic eraser and gently remove the rubber or let the plastic soak in water and soap for a few hours and rub it off with a coarse cloth.

Another possible yet less practical solution might be to replace mk09bo optical sensor entirely with a superior one able to operate on transparent surfaces, but it would have to match the PCB pinout.

Laser mod What separates an “optical” mouse from a “laser” mouse is simply the type of light emitting diode used. David Hill the industrial designer of the mouse remarked: The original ScrollPoints used a “cat’s tongue” TrackPoint cap: I’m not exactly sure what makes them slower since they’re both DPI according to IBMhowever I presume this is either the optical sensor or the microcontroller. Flashing the controller will require desoldering the Cyprus microcontroller and adding a socket; relatively easy if you have soldering equipment.

Be careful not to cut too deep and slice away the plastic. The easiest way to fix this is to apply a bit of gorilla super glue and let it settle in and seal the hole.

Various online sellers and auctions will generally have ScrollPoint mice available in bulk. For some reason only the ivory version has the IBM logo printed up near the top of the mouse instead near the bottom like the other ones, AND later black ones used a silver logo.

Upon removing the top bezel, the buttons omuse actually detachable from the bezel. Availability ScrollPoint mice generally go under the radar as not too many people are acute to them. Fixing the divot on the button plastic. Omuse mice came in two colours, black and ivory: If you’re moderately gentle the original porous texture underneath the rubber will be preserved.
