Bill Duvall, an SRI researcher, spent about a month writing a clever program for the 940 that essentially fooled it into thinking it was communicating not with another computer but with a “dumb” terminal. A dumb terminal can neither compute nor store information; it serves only to display the most recent set of information sent to it by the computer to which it’s linked. Duvall’s program was a very specific interim solution to the host-to-host communication problem.
