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.
