Ok, got some photos here. I took the 555s out completely; it's just the 4093 going right to the 40110's. I did figure out the issue with both switches needing to be pressed. After I thought about it a little more, I realized it's pretty obvious that the output pins had to be joined...and they were! So my sleuthing skills need to be upgraded a little.
Unfortunately, the one quadrant of the 4093 is still making the counter change by two. I tried moving the .1uf capacitor and 100k resistor from pin 1 to pin 2, but that didn't change anything. And also, it is incredibly consistent that it changes by 2. I can get a video if you want to see it.
And to explain a little more how I set everything up; the 40110's on the left side of the board are driving the "in process" side, so the 4093 outputs are going to the clock up and clock down pins of the lower left, and that borrow/carries to the top left 40110. On the right, that is the "target" number (only set once a day, presumably) so I just have outputs going to the clock up on both 40110's. (one button per digit), so that you don't have to clock through more than 9 presses per digit. That way, you can set any number in 18 button presses or less, instead of 50 presses as the other side is. Uh, if that makes sense.
So, as it stands; I think I'll just stuff this all in my enclosure as is. I'm getting antsy to see it all together.
The in-process side will clock down by two, but as a prototype, I think it's fine. I was actually toying with the idea of having only two buttons, and a toggle switch to make the buttons control only one side at a time. That way, the "target" side will be more difficult to change accidentally.
One more question, though. Would ribbon cable be the best choice to connect the LEDs to the board? I looked around a little at the cable, headers, etc., but I'm not quite sure what is the appropriate way of doing it. Something tells me that the phone cord I used this time isn't "industry standard".
