Here’s a comparison between an earlier sage SP Pro with the 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: You are logged in as. Another possible yet less practical solution might be to replace the optical sensor entirely with a superior one able to operate on transparent surfaces, but it would have to match the PCB pinout. Flashing the controller will require desoldering the Cyprus microcontroller and adding a socket; relatively easy if you have soldering equipment. Sets mouse sample rate. Sometimes they are listed under 31P, I think this might be only on very early models from

Searching the web suggests that MO27FO is the version with a wheel, not a scrollpoint. No intentionally harmful or joke advice. Does the wheel light up like the ScrollPoints on later ScrollPoint-equipped mice?

It is by far the most comfortable mouse I have ever used. A USB mouse device that is added and configured after the open operation is automatically added to the open set. If you’re running a Slate Blue rev.


The client driver has no knowledge of the underlying USB adapter hardware. Note that your submission may not appear immediately on our site.

If you have different coloured ScrollPoints, you can mix and match button colours. The first version of the standard three-button ScrollPoint mice were announced in around They came in black and ivory, with the exception that both used blue printing of the IBM logos.

Make sure there is no excess glue to make the buttons taller in height than they were originally: I need mouse for my work computer, the one I have just kind of makes me sad.

Sexually explicit or offensive language. I’m not sure what existing IC is in use by the ScrollPoints or other optical mice which use similar indiscreet sensors.

Some people are laughably dumb I’ll function as ib international shipping hub if anyone overseas is interested and seller agrees to ship to Canada.

They’ll have patent 5, referenced at the bottom for the optical mechanism that determines the movement of the mouse ball. The original ScrollPoints used a “cat’s tongue” TrackPoint cap: The following input device driver ioctl operations are used for the USB mouse operations: I wanted that auction, now everyone is gonna bid.


Please submit your review for IBM Mouse. It’s also possible to replace the 5mm red optical sensing LED to blue.

However, the stark blue doesn’t quite match the translucent mouze blue” ScrollPoint cap which is very close to lavender. It just fits my hand perfectly.

Therefore it may be possible to replace the existing red LED with an infrared one. As ScrollPoints offer superior functionality to the standard ‘wheel’ mechanism, it’s very curious why this alternative design never overtook standard mice. It is possible to ‘donate’ the rubber siding from the ball ScrollPoint Pro lbm the optical one, this does require some minor modifications however. Sets mouse sample rate.

The antique sage ones mousse prized for their unique look, however. The firmware which controls the ScrollPoint mechanism is flashed onto these Cypress microcontrollers. These mice came in two colours, black and ivory:
