Keyset from a Xerox Alto II XM
The following is a keyset from the Xerox Alto II XM and was used in the manner of the original keyset from Doug Engelbart's group at SRI, to provide two handed access to software interfaces, affecting seletect text and operating frequenly used menu itums. This device is a bit like a piano keyboard and allows you to operate interfaces without using the keyboard. Sounds of the rapid clicking of keysets at Xerox PARC was an indication that researchers were playing Maze War.
