I'm trying to route 12vdc and to digital lines to a selected PIC, so I can program individual PICs via ICSP on a bread board without moving the wires around. I figured out how to route the 12vdc after much pain and sufferring, and a lot of help from a thread in General Electronics Chat, but I still need to figure out how to route the clock and data lines. I have some 74LS245s in front of me, but they need the DIR line to determine direction, and I haven't a third line to tell me whether the PICs are reading (programming) or writing (verifying or read mode). Is there another way?
