Microsoft Introduces 2-Button Mouse

Microsoft Corp. announced the two-button Microsoft Mouse, which it introduced to go along with its new Microsoft Word processor. Microsoft built about 100,000 of these fairly primitive units for use with IBM and IBM-compatible personal computers but sold only 5,000 before finding success in a 1985 version that featured, among other improvements, near-silent operation on all surfaces.
