By the mid-1960s, almost half of all computers on the earth had been IBM 1401s. The first large-scale pc communications community, SAGE connects 23 hardened computer sites within the US and Canada. Its task was to detect incoming Soviet bombers and direct interceptor aircraft to destroy them. Operators directed actions by touching a light-weight gun to the SAGE airspace display. The air defense system used two AN/FSQ-7 computers, each of which used a full megawatt of energy to drive its 55,000 vacuum tubes, one hundred seventy five,000 diodes and 13,000 transistors. The machine used up to sixty five,536 one-bit processors and will full a number of billion operations per second. Each processor had its personal small reminiscence linked with others through a versatile community that customers altered by reprogramming somewhat than rewiring. The machine´s system of connections and switches let processors broadcast information and requests for assist to different processors in a simulat
