Three Button Mouse from the Xerox Alto
(with keyset)

The following is a three button mouse from our Xerox Alto II XM and was derivative of the first mouse produced by Doug Engelbart's group at SRI in the mid 1960s. We also have in our collections and Alto keyset, the first Microsoft Mouse and the first joystick created for an Apple computer. Gary, a DigiBarn visitor, later sent in photos of an original Alto wheel mouse that he has in his collection.
