Hi all, I'm wanting to set up the bistable latch to use as a demonstration with my year 11 class for the OCR Gateway P6 unit. We've got a set of NOR gates to use now and an LED to use as an output device, but I have been struggling to set up the circuit. I've never really studied electronics (at school or at university) so have no expertise in this area at all. I have the diagram below from the teacher/technician info we have, and I can set this bit up no problem, but I can't get my head around where A and D connect to, or where the two output wires go either. I've asked around in the department, and no-one can answer my question either. EDIT: no idea how to upload a picture on here, and help is much appreciated!
