n A digital data processing subsystem comprised of redundant central processor units plus companion input/output units, resident software, digital data buses, and numerous remote bus terminal units would function as the core subsystem to interconnect all avionics subsystems. It also provided the means for the crew and ground to access all vehicle systems (i.e., avionics and non-avionics systems). There were exceptions to this, such as the landing gear, which was lowered by the crew via direct hardwired switches. Engineering Innovations 243
