Abstract : The ASCII decoder described in the report accepts inputs from an acoustic coupler, or Modem, in a remote time-sharing system. On receipt of a special command character the decoder recognizes, stores and decodes the next two decimal digits. The output can be used to access any one of 100 items. For example, the decoder allows a random-access slide projector to be operated under computer control. The report contains complete specifications, including a description of the functions of the circuits in the decoder. (Author)
