Tektronix Inc’s UK subsidiary in Marlow, Buckinghamshire, has reimplemented software written for Sun Microsystems Inc workstations to run on its own 4300 series of graphics workstations. The latest 3.0 release of the Unix-based UTek operating system enables users to access Sun-3 binary programs, any application that uses Tektronix drivers, and any software written for X-Window. PDA Engineering’s Patran ME/CAD system now runs on Tek workstations.
