PLATO Terminal Screen

PLATO端末の画面 / 1972–1980s / Style / Platform Screen Languages

PLATO was the computer-assisted teaching system started at the University of Illinois in the early 1960s under Donald Bitzer, and its screen is a style in its own right. It ran on plasma flat panels with touch input, and the TUTOR language placed text and drawing by coordinate rather than by line flow, so a lesson was assembled straight onto the surface. Its notes files, private messages and multiplayer games set the shape of later online screens.

Dictionary entry

Type: One monospaced face only, with no weight contrast and at most two sizes.
Composition: Place text at chosen coordinates instead of flowing lines, and separate areas with empty space rather than frames.
Material: Black ground, one glowing orange and no midtones, with the density of dots and strokes carrying the tone.
Caution: Adding scanlines and bloom to make it feel like a cathode ray tube erases the one thing that defined this screen, a flat plasma panel that glows without smearing.
