A friend asked me about cable testing. He has a need for a tester for terminated cables. I was speculating about something decoder based; Pin 12 on A end is excited, and B looks for that AND looks at 1-11 and 13-40 for anything that should't be there. Then light up pin 13, and iterate. What's the Brane Trust's ideas on how to do this?` -- A host is a host from coast to coast............

Assuming one back-plane to consider , what would be most efficient component-count/least complex discrete/CMOS/74 route , ie not pic/Pi/uC to firstly convert the ex-oring business to proper levels and then the "mapping", output could be linear per digit rather than bcd. Starting with an off-the-shelf commercial unit where the LCD display is driven off a uC, to give a remotely monitorable ...
