5/82.2.1.3 TICCIT
TICCIT (Time-shared Interactive Computer Controlled Instructional Television) was the second major authoring system to by funded by the NSF. It was developed at the Institute of Computer Uses in Education at Brigham Young University in the early 70's and distributed by Mitre Cooperation. The system was based on Merrill's concept of Component Display Theory. The concept was different to that of PLATO where the users had complete control how their lectures would look like. In TICCIT the frames always had the same appearance independent of the author and subject. A frame was either an objective, rule, example, practice or a help component. In addition, students using the TICCIT system could choose between different degrees of difficulty.A TICCIT server could serve up to 128 terminals which consisted of a special keyboard and a colour TV. In contrast, PLATO mainframes could serve up to 1000 terminals. Today you can find several hundred TICCIT systems running on microcomputers.
