Remote Access Computer Output over ITV Systems

The United States Military Academy at West Point, N. Y., has used a time-shared computer system in support of the academic program since 1965. The requirement has existed, however, for a highly flexible, portable access terminal-one more portable than the bulky communication or video units normally labeled as portable. It was felt that a terminal that could be used in any classroom or auditorium where the students could view both input and output would be far more suitable to the teaching environment. Such a terminal would allow instructors at West Point to use computers for reinforcement of teaching points and as a medium of demonstration. This requirement has been met through the integration of a PDP-8/I, a DF-32, and a video-display generator with the time share system and the instructional television system. Now the only equipment that has to be moved into the classrooms is a keyboard-entry device built into a 22-, by 16-, by 5-inch case. Since each classroom and auditorium has receivers placed to cover a maximum audience, the input and output is distributed via the instructional television system (ITV). The system is now fully operational. For in-class instructional support, it has proven itself an extremely flexible means of gaining access to the time-share system.
