Like all things, eventually these mice will be harder to find as time goes on. The differences with these ones is that they now use an DPI sensor instead of the optical-sensing ball; the sides are now coated with the rubber paint and the ScrollPoint mechanism now lights up! 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 came in black and ivory, with the exception that both used blue printing of the IBM logos. Flashing the controller will require desoldering the Cyprus microcontroller and adding a socket; relatively easy if you have soldering equipment. 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.

Searching the web suggests that MO27FO is the version with a wheel, not a scrollpoint. Once I determine the cause of the increased sensitivty of the revision B ScrollPoints I will report back here. If you’re running a Slate Blue rev.

I need mouse for my work computer, the one I have just kind of makes me sad. These early ScrollPoints were mistakenly reported to use pressure pads instead of the resistance measuring mechanism mo27foo found on the TrackPoint.
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 mo7fo the microcontroller. Become a Redditor and subscribe to one of thousands of communities.
Vintage IBM Scroll Optical Mouse Model Mo27fo
Queries mouse device identifier. Laser mod What separates an “optical” mouse from a “laser” mouse is simply the type of light emitting diode used. Some minor changes need to be done, either miuse tabs on the optical base or the older silver top need to be cut. Metallic Black Depth Metric: Some of the earlier ScrollPoint Pros suffer from misaligned buttons at the assembly ihm which results in a click response that isn’t as crisp and slightly spongy.
The easiest way to fix this is to apply ml27fo bit of gorilla super glue and let it settle in and seal the hole. The revisions are colour specific: They discontinued the more elaborate ScrollPoint III Pro Model 31P as pictured above inpresumably due to the cost of manufacture and little demand.
Another possible yet less practical solution might be to replace the optical sensor entirely with a superior one able to operate igm transparent surfaces, but it would have to match the PCB pinout.
A device special file is created for each USB mouse device. You are logged in as. After in extensive use the microswitch will cut the plastic of either left or right clickable buttons and the thumb button if you use that frequently. Unfortunately, I think they stopped making it a decade ago.
Link mo72fo are not permitted. 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.
Flashing the controller will require desoldering the Cyprus microcontroller and adding a socket; relatively easy if you have soldering equipment. These are probably the harder ScrollPoint Pros to find, but also some of the least desirable due to their DPI ball mechanism.

As ScrollPoints offer superior functionality to the standard ‘wheel’ mechanism, it’s very curious why this alternative design never overtook standard mice. These mice featured an ergonomic curve while retaining sharp angles, and the third button has been moved near the thumb area. Click on the following links for the driver package readme info: Does the wheel light up like the ScrollPoints on later ScrollPoint-equipped mice?
The differences with these ones is that they now use an DPI sensor instead of the optical-sensing ball; the sides are now coated with the rubber paint and the ScrollPoint mechanism now lights up! Most mice will have red sensor LEDs as they are cheaper to manufacture and more responsive to the sensing Mousee.

It is possible to swap parts with the later MBO optical ScrollPoint Pros mo27ro you want to convert your optical ScrollPoint Pro to mp27fo a different colour, or borrow one of the rubber sides to replace your worn down one.
Here’s a comparison between an earlier sage SP Pro with moue later revision where they corrected this with an updated injection mold, you’ll see how the older revision has both of the buttons veering to the right causing an uneven gap and this isn’t just the photo angle:. After this you will need an X-ACTO knife to cut away any excess, if you do not the buttons won’t align properly disallowing them to click.
ScrollPoint mice generally go under the radar as not too many people are acute to them.
