The Tektronix 4010 Graphics Terminal


The Tektronix 4010 Graphics Terminal, 1972. The pedestal is part of the terminal; it's full of electronics. The one shown is in Columbia University's SSIO area, circa 1982. Note the PACX box on top to select the desired host computer, and the thumbwheels on the right side of the keyboard for moving the crosshair cursor.
