Microsoft Mouse

The Microsoft Mouse is a computer mouse released by Microsoft in 1983. It is the first mouse released by the company, and it was bundled with Microsoft Word, Notepad, and an on-screen teaching tutorial for an initial price of $195.
Nicknamed the "green-eyed mouse", the Microsoft Mouse featured a pair of green buttons. It also featured a more curved body than the blockier designs more common of mice at the time. As with other mice at the time, the Microsoft Mouse used a steel ball for tracking.
The initial version featured an InPort ISA interface, requiring a Microsoft bus card to be installed in the computer. Later versions were available with DE-9 or DB-25 serial connectors. All versions of the Microsoft Mouse could be used with IBM-compatible and other DOS systems.

The "kidney" Microsoft Mouse 2.0 was introduced in 1993, and its design served as the basis for the IntelliMouse, which debuted in 1996.
