I have used it (though briefly) attached to a SUN workstation, and it is quite nice. It will be able to detect rotation as well as translation. Price: $286, qty 1 (??) Apple-II interface: $51 IBM-pc interface: $51 RS-232 interface: $40 Availability: 2nd Q, '83. The address: Mouse Systems Corp. 655 Fairoaks Ave., Suite D-313 Sunnyvale, CA 94086 408-730-2132 Have fun, Herb Jellinek (lime!burdvax!hdj)
