Talkomatic is being developed by Dave Woolley and Douglas Brown at the University of Illinois as a multi-user chatroom application. It is an instant sensation among users of the PLATO system's online community.
TERM-Talk is developed by the staff of the Computer-based Education Research Laboratory at the University of Illinois as an instant messaging application that allows any two users of the PLATO system to have a live conversation, typing character by character on the bottom of the screen of their PLATO terminals. Soon many features were added, including "monitor mode", which allowed one user in the TERM conversation to share their own screen with the other user to ask questions or point out something they were seeing. Years later, this concept would be introduced as "screen sharing" or remote desktop software.
PLATO Notes is developed by 17-year-old student Dave Woolley at the Computer-based Education Research Laboratory at the University of Illinois as a conference and bulletin board forum system for communicating with the user community. In 1976, Notes was expanded to allow any user to create a "note file" on any topic. PLATO Notes was to serve as the inspiration for Lotus Notes, which was developed by former PLATO users Ray Ozzie, Len Kawell and Tim Halvorsen.
