Tektronix DVST Graphic Terminals: Pioneers of Computer Graphics Displays

2024-12-19

This article recounts the legendary story of Tektronix's DVST (bistable direct-view storage tube) graphic terminals. From Bob Anderson's invention of the DVST in 1961, to Tektronix's launch of its first 611 display, and later the iconic models T4002, 4010, and 4014, Tektronix spearheaded the development of computer graphics display technology. These terminals, with their high resolution and stability, became essential devices for computer graphics applications at the time, ultimately driving the progress of the entire industry. Even after the advent of low-cost raster-scanned CRTs, Tektronix's DVST terminals held a significant market share for years due to their compatibility and reliability.

Tektronix's 'Unicorn' Graphic Terminals: A Legacy of Low-Cost Color Displays

2024-12-15

In the 1980s, Tektronix launched the 4100/4200 series graphic terminals (nicknamed 'Unicorn') to enter the low-cost color terminal market. The project faced challenges, including the destruction of a crucial prototype, but successfully delivered models like the 4105, 4107, and 4109 ahead of schedule. The 4200 series further reduced costs and improved performance, eventually incorporating networking capabilities. These terminals gained wide adoption due to their cost-effectiveness and compatibility, becoming a significant part of Tektronix's legacy.
