ABSTRACT:
An interface apparatus for interconnecting signal lines of a computer connector and a peripheral device connector with non-matching interconnect patterns having mismatched data lines or open inputs on handshake or control lines. A pair of conductive paths extend between the connectors, with each path interconnecting one data line of the computer connector with one data line of the peripheral connector. Lights indicate mismatched interconnection of the data lines, and a switch selectively reverses the interconnection of the data lines. Additional conductive paths extend between the connectors, each path interconnecting at least one handshake or control line of each connector with at least one handshake or control line of the other connector. Two pairs of interconnecting handshake lines are each provided with a switch in gang with the data line switch for selectively reversing their electrical interconnection. Four current-regulating field-effect transistors are each connected between one of the handshake lines and a common node, and act as a conductor when an enable signal is present on its line and as a current-limiter when an open input is present on its line. Resistors are connected between the common node and each of the remaining handshake or control lines.
