IBM Mouse Model 12J3619 (PS2)

Circa 1997

Use Case:

Used in general desktop computing in office and home settings, offering a reliable, ergonomic input device compatible with PS/2 ports. Its key distinguishing feature was the inclusion of the blue ScrollPoint nub, which allowed for both vertical and horizontal scrolling within documents and web pages without needing a typical scroll wheel. The mouse uses two buttons for primary interaction (left/right click) and the nub acts as a third, programmable function button when pressed.

Historical Significance:

Historically significant as part of the transition away from the original mechanical ball mice and an alternative to the emerging scroll wheel designs. It was notable for integrating the iconic TrackPoint pointing stick technology, well-known from IBM ThinkPad laptops, into a full-sized desktop mouse. This provided a unique scrolling solution that differed from standard scroll wheels and highlighted IBM's focus on innovative ergonomic features in its peripherals. The design was produced by LOGITECH for IBM under model names such as MU29J, M-SAU-IBM6, and others.
