Stan, I have some SN74HC86N and CD4070BE ICs. I'll follow your instructions above and see how it goes. However, in my massive shop and parts re-organization project (currently underway) my entire assortment of CMOS ICs are temporarily MIA, but the 74xx ICs are right where they are supposed to be. Half the battle lately has been just finding things. Not sure the difference between the AC and HC versions, but I am guessing the HC will work too. I'll be looking at the datasheet anyway.
Some of GRJ's PIC chips listed above have been added to my next Digikey order. Somewhere around here I have the traffic signals working on an Arduino Uno from previous fiddling a few years ago. I'll save that and the PIC trials for another thread, good idea. It might be a while on that one though, I need to do some studying and learning with the PIC.
GRJ, as I said to Stan above, I have this for Arduino, but I like the idea for the PIC and one PCB solution as you suggest. I am guessing that the PIC code will be similar to the Arduino, if so it shouldn't be too difficult, but I haven't tried it yet either. Sometimes the 'doing' is a bit worse than it seemed in my first thoughts. I just need to learn the PIC pin outs and their functions. I don't suppose my PICKIT 3 will do for this? In that case I'll need to get a PICKIT 4, probably a good idea anyway. I don't mind that as I have always wanted to learn more about the PIC chips since I read some articles on the PICAXE a few years ago. All this should keep me busy (and off the streets 
) for a while.
Finding my CMOS ICs might occupy quite a bit of time, I can't imagine what I did with them, I had quite a variety too, more so than the 74xx series stuff. I have been in some state of disarray with one thing or another since we moved almost 6 years ago! I have moved things around several times and so nothing has seemed "just right' as it was in our old place. You are probably already in much better shape than I am, but I'm sure you can relate!
