Abstract : Progress is reported on a continuing feasibility study of the Variable Computer System. Since the results showed the predicted saving in computing times by the factor 2:1000, depending on the types of computations required, the efforts were turned to the crucial questions of establishing communication between the fixed and variable parts, of physical construction of the system, of supervising control and basic inventory, and in particular to the questions of testing and designing of high speed switching elements and packaging. A system to simulate transfers between the IBM 7090 and the variable part of the system has been constructed and the conjecture that 72 bit transfers are feasible in one IBM memory cycle was substantiated. Further problem studies as well as studies of special components, such as content-addressable memory were executed on a limited scale; in addition, studies of procedures in the efficient assignments of the available variable hardware inventory on dynamic basis in parallel processing of one or more problems were initiated.
