RE PORT STATUS OF PLATO IV Bruce Sherwood Computer-Based Education Research Laboratory University of Illinois, Urbana 6180i The Computer-based Education Research Laboratory of the University of Illinois zs developing the PLATO IV system to provide high-quality computer-based education at low cost. When fully implemented, the PLATO IV system will consist of a large central computer simultaneously serving several thousand state-wide users of graphics terminals, with response times of a fraction of a second. The estimated cost per user i s fifty Cents per hour, including operating expenses, such as communications charges and management, and amortization of capital costs for the computer and the graphics terminals. The research and development effort over the past twelve years has resulted in important innovations in terminal and communications hardware and in system and teaching software. The heart of the PLATO IV terminal is the plasma display panel, now being produced by Owens-Illinois of Toledo, Ohio. The panel measures 8.5" x 8.5" x 0.5" and is a transparent 512 x 512 dot matrix display with inherent memory. Individual dots can be written or erased without disturbing the rest of the display. Terminals incorporating plasma panels are being built to PLATO specifications by Magnavox,
