A Tutorial for Use of the TENEX Electronic Notebook-Conference (TEN-C) System on the ARPANET
A 1975 technical instruction manual produced for users of the TENEX electronic notebook-conference system on the ARPANET, prepared by the Defense Technical Information Center and linked to the University of Southern California's Information Sciences Institute. The single picture is a flow diagram of the TENEX prompt branching into programs such as XCONFER, XED, MSG and other programs, each with its own input and a shared Change step, which a designer could borrow as a clean schematic of hierarchical menus and connecting arrows.
