This report describes a graphics terminal designed as a remote computer input-out terminal for unsophisticated users. The first chapter focuses upon the terminal's plasma display panel, its self-contained character and line generators, and its ability to communicate over low grade telephone lines. Chapter 2 concentrates upon operating modes,…

A low cost communications network has been designed for use in the PLATO IV computer-assisted instruction system. Over 1,000 remote computer graphic terminals each requiring a 1200 bps channel are to be connected to one centrally located computer. Digital data are distributed to these terminals using standard commercial cable television (CATV)…

The PLATO IV computer-based educational system contains its own communications hardware and software for operating plasma-panel graphics terminals. Key echoing is performed by the central processing unit: every key pressed at a terminal passes through the entire system before anything appears on the terminal's screen. Each terminal is guaranteed…
