The Wilsonville site opened in 1975 and was home to the Information Display Division (IDD) in building 60.  These groups had remained on the Sunset Plant site which was so over crowded that they brought in portable trailers.  Here is a TekWeek article about the construction of the Wilsonville site.

IDD had three main groups: Information Display Products (IDP), Information Display Systems (IDS) and Information Display OEM (IDO).  IDP was responsible for the line of graphic terminals including the 4010 series direct view storage tube (DVST) terminals, the 4020 series of raster graphic terminals, and associate hard copy units.  IDS was responsible for the 4081 and 4050 series of graphic desktop computing systems and associate peripherals such as the plotters.  IDO was responsible for OEM products which consisted mainly of the GMA DVST monitors.

These groups morphed over time.  Eventually Graphic Computing Systems (GCS) took responsibility for the 405X family of products.  There was even a Mechanical Engineering Graphics (MEG) group to create software for the Mech Eng market that could leverage Tektronix hardware.  Building 61 was added onto Building 60 to accommodate the growth.

Tektronix later chose to exit the computing systems business and focus on terminals and hard copy products.  The hard copy products initially were peripherals to the Tektronix terminals, but refocused on the general purpose computing market.  Eventually they were broken off and became Graphic Printing and Imaging Division (GPID).  Building 63 and 83, a warehouse,  was added to the site was added to accommodate more growth.  The terminals group was divided into low end terminals as Graphic Desktop Products (GDP) and high end terminals as Graphic System Products (GSP).  Eventually Engineering Computing Systems (ECS) was formed to develop engineering workstations (some noticed that ECS was GCS with a parity error).  These products were developed around the ill-fated National chip set and after developing an initial family of products was disbanded.  Artificial Intelligence Machines (AIM) was formed to develop the 4400 series of Smalltalk workstations.  Eventually GSP evolved into Graphic Workstation Products (GWP) and developed a family of workstations using the Motorola 88K family of processors.  However, the market was well entrenched with the likes of Sun and Apollo workstations and few applications were ported to Tektronix workstations.

GPID continued focusing on printing with breakthroughs in color wax technology and became the Color Printing and Imaging Division (CPID).  With the terminal market waning both GDP and GWP were closed but a new group focusing on network-based computing emerged as Network Displays (NWD) that developed a family of color X-Terminals.  By the mid-90s it was clear that video, computing, and networks were converging and Tektronix formed the Video Networking Division that merged the video disk storage (Profile) portion of TV Products and NWD and consolidated on the Beaverton campus.  CPID took over the entire Wilsonville campus as their color printing business grew.  In 1999 CPID was sold to Xerox as Tektronix divested of VND and CPID to return to its roots as a Test and Measurement company headquartered in Beaverton.
