Terak Graphics Computer System

The Terak Graphics Computer System is an early graphics workstation built around the DEC LSI-11 microprocessor.

From Terak

The Terak was manufactured in Scottsdale, Arizona in the late 1970s. The graphics system consists of a memory mapped frame buffer of 320×200 pixels with video scanout circuitry. In many ways, the Terak was the precursor to the graphical unix workstation that became dominant in the 1980s.
