A Machine Organization for a General Purpose List Processor

A general purpose list processor organized machine is postulated that: 1) carries out directly the basic processes involved in list processing, 2) includes arithmetic and other features needed for a general purpose machine and 3) adapts to operation in a wide variety of programming languages. The power of the machine is achieved by using a small fast scratch pad memory for manipulating address fields and by including an automatic symbol table in the form of a search memory. Two basic list orders, a transmit order and a structure tracing order, determine the fundamental organization of the machine and are summarized.
