An instrument is described which is used to multiplex the “ready” and “external sync” lines of an IBM 1800’s data channel to 15 external devices. Used with the digital output registers of the computer, the device facilitates the interfacing of non-IBM peripheral devices to the 1800. The multiplexer can be used in any application in which a pair of lines needs to be shared among several devices.
