摘要：An interface (10) between a first (MC, 30) and second (SC) computer employs amultiplexer (46) and a coupler (48, 50). The first (MC, 30) and second (SC) computers havea first (LA/B, LEX0-15) and second (CX1-21, CA1-15) plurality of information lines,respectively. These computers also each have a group of control lines (36, 42). Themultiplexer (46) is connected to the first and second plurality of information lines (LA/B,LEX0-15, CX1-21, CA1-15). The multiplexer (46) is operable to separately switch each of apredetermined group (LEX12-15) within the first plurality (LA/B, LEX0-15) between eithermember of a different corresponding pair within the second plurality (CX1-21, CA1-15).The multiplexer (46) is also connected to at least one (ESELCX) of the control lines (36) ofthe first computer (MC, 30). The multiplexer (46) can switch the predetermined group(LEX12-15) in response to a signal on the control lines (ESELCX) of the first computer (MC,30). The coupler (48, 50) is connected to a given assemblage (CX1-20) within the secondplurality (CX1-21, CA1-15) and to a predetermined set (LBIN1-15, LAIN12- 15) within thefirst plurality (LA/B, LEX0-15). The coupler (48, 50) is operable to transmit signals to thesecond plurality (CX1-21, CA1-15) from the predetermined set (LBIN1-15, LAIN12-15).
