This engineering research program, undertaken to construct a 5000 word cryogenic associative data processor, achieved its intermediate objectives concerning identification and solution of technical limitations for large capacity array fabrication, interconnection, data linkage, and packaging. Successful methods for fabricating 2.0 inch x 2.25 inch arrays having 40-word, 2000-cell 11,000 cryotrons capacities resulted in seven operable arrays by the end of the program. Between 126 and 144 such arrays would provide the 5000 word objective. Fault-tolerant system operation permits use of arrays containing failed words. Array interconnection via superconducting, flexible, strip transmission line in pressure-actuated contact with thin film array contacts was successfully used throughout the contract, as were preferred data linkage means. Design concepts for packaging the multi-array system were accomplished, and the interface electronic functions to permit on-line operation with a Univac 1218M computer were specified. Because solution of array fabrication problems consumed most of the contract period, fabrication of the full complement of arrays was not possible. An engineering development program is recommended for construction of the 5000 word cryogenic associative processor.
