In an undated ad, Hawley Mouse House boasts about inventing its first digital mouse in 1972. (Stanford Making the Macintosh) The Alto I mouse substantiates this claim to fame by its prominent embossing of the name Hawley alongside Xerox on its innards. It wasn't until 1983, however, that Jack Hawley produced his own mouse, the Mark II X063X, with his company name only and the copyright year emblazoned inside.
The Hawley mouse looks industrial with its sparse little block design and homely black plug, compared to the contemporary Xerox Star mouse. The bottom of the Hawley Mark II is reminiscent of the Alto's mouse except with the cord on the opposite end. The Hawley's big stainless steel mouse ball resides at the wrist edge and communicates the x-y coordinate position to the cursor. Two small stainless steel balls serve as rollers on the cord end. The Hawley mouse motherboard looks akin to the Alto mouse's, but brightly colored, much prettier than the outside.
A patent filed by IBM in 1995 for a pointing device cites the Hawley: "Two different implementations of the mouse protocol unit 37 have been known. One involves quadrature signals (pulse trains) and is known as a parallel implementation. The parallel implementation was developed and manufactured by Hawley Laboratories of Berkeley, Calif." (Patent 5764219)
Hawley ads featuring the 1983 X063X mouse undoubtedly target engineers and military technicians, who were some of the earliest computer users. Hawley must also intend to challenge input devices produced by Koala and Mouse Systems for personal computers. One ad claims,
"the MOUSE HOUSE™ is superior to any other mouse made. Its combination of accuracy, speed, and ease of operation is impossible to attain with input devices such as touch tablets, light pens, or track balls." (Stanford Making the Macintosh)
Another ad states the specifications:
"The HAWLEY X063X Mouse moves the cursor in any direction on a computer display screen, in direct proportion to its own movement, with a resolution of 200 ppi. The user-friendly Mouse rolls freely on any convenient surface." (Stanford Making the Macintosh)
