This Microsoft Wheel Mouse is a reliable and versatile device for all your vintage navigation needs. It is used but overall in good working condition and feels comfortable. Was actually used to test a few of my vintage PCs via PS/2. This mouse is compatible with both PS/2 and USB connectivity, via the PS/2 adapter, providing flexibility in its use. The retro beige color and 3-button design make it a classic and functional addition to any workspace.
