I think I'll need to borrow an oscilloscope and see what's going on. Frankly, I think I just made too many mistakes during assembly. Since I know at least four I made and corrected, I suspect another four luck under the cover. The primary oscillator seems to be running, but I am no longer certain the divider is running (it did when I previously tested it, but who knows...)
I'll work on it some more again soon.
