Sony Microsystems Co, Palo Alto, has signed to use Santa Clara-based Parallax Graphics Inc’s Viper series of high-performance colour graphic and videographic display controllers with its NEWS family of multiple 68030-based Unix workstations. Equipped with the optional Viper video input card, a VMEbus board that can be used with 32-, 16- or 18-bit microprocessors, the workstations will be able to be used in such multi-media applications as video production and computer-aided instruction. The Vipers include device drivers for the X Window System Version 11. Under the agreement, Parallax will provide its products directly to Sony end users and to resellers of the workstations, with Sony and Parallax co-operatively marketing Viper under Sony’s Synergy marketing programme that covers the Synergy catalogue of products available for use with the NEWS. Parallax Graphics is an independent unit of Dynatech Corp.
