Ross and the other researchers from the Massachusetts Institute of Technology Lincoln Laboratory were the sole users of the complex display systems installed for the pre-SAGE Cape Cod system.

Ross saw the 'interactive display equipment' being used by radar operators, believing it would be exactly what his SAGE-related data reduction group needed. Some of these developments include servo-motors controlled by generated pulse (1949), a digital computer with built-in operations to automatically coordinate transforms to compute radar related vectors (1951), and the graphic mathematical process of forming a shape with a digital machine tool (1952). Circuit design theory or power network methodology was algebraic, symbolic, and often vector-based.īetween the mid-1940s and 1950s, various developments were made in computer software. Digital computers were used in power system analysis or optimization as early as proto-' Whirlwind' in 1949. ( January 2022)ĭesigners have used computers for calculations since their invention.
