The development of systems for on-line mathematics at Harvard
Adrian Ruyle · 1967
Project TACT (Technological Aids to Creative Thought), in the Aiken Computation Laboratory of Harvard University, has been designing, implementing, and using on-line systems since 1964. Our investigation has concentrated on a rather small class of interactive systems which are "dedicated," that is, tailored to provide a coherent set of tools for mathematical assistance, and which use fairly powerful terminal facilities: display scopes and natural input.
