The way to do the set and reset with the PBs is to put the resistors from the inputs to ground as a pulldown. Then connect the PBs between the inputs and V+. Pushing the buttons will the put a logic one on their respective inputs. Otherwise the outputs stay at logic zero.
Heh; that's 'zactly what I ended up doing, and it worked fine. Used 22k resistors (that's what I had). Thanks to you.
So before you answered I prepared this sketch to ask you a couple more questions about this:
**broken link removed**
I omitted R1, and just had R2 betwixt gate pin and ground.
In general, what's good practice with CMOS inputs? (Yeah, I know, it depends ...) Just looking for general guidelines here.
By the way, my little test circuit works; chases a LED around a loop. Not very exciting, I know, but it's my first logic circuit ever! so it's just a little bit exciting.
But, of course there's a major problem, which would be a show-stopper for those circuits I drew for other people: the lights are very flaky. Sometimes they go in sequence, but more often they skip around drunkenly.
Can you say "switch bounce"?
So how do I deal with that? Do I really need a one-shot? Would Schmitt triggers help? Is there a simple wave-shaper I can make, just a capacitor or three? I know this is a topic unto itself, and I will do a search here, but since this problem has reared its ugly head here I thought I'd bring it up.
===== Later, in a different part of the forest: ======
Lotsa stuff here. I found this picture in a good PDF someone posted (including all the math needed to size R & Cs):

More parts than I had hoped for, including yet another gate. Anyone have experience with this arrangement? I'm sure it works; I'm just wondering if there might be something simpler that would work well enough. (This is not going inside the Space Shuttle.)
