IBM Mouses

All but the first IBM mouse, at the bottom left of the photo, used to connect with IBM's own PS/2 plug. The PS/2 became the standard mouse port after it was introduced on the IBM Personal System/2 computers in 1986. The USB protocol replaced it in the 1990s, as on the two black mice top right.
