Vintage Microsoft InPort Mouse with serial and IBM PS/2 interface adapter. This classic "Dove" style mechanical ball mouse features a two-button design and a cream-colored finish that has developed a natural vintage patina. The unit includes the original cable with a 9-pin circular connector and a specialized interface box (FCC ID: C3K76FMA) designed for compatibility with older computing systems. Made in Japan, this piece of computing history is ideal for collectors of retro hardware or those restoring period-correct PC setups.
