Analog, the oscillator and input LEDs worked. The 220R on the LEDs needs to be 1/2W.
The value of C1 ended up needing to be left at 1 uF, otherwise, when using the 0.1 uF, if the power is cycled while one of the alarm inputs is being held high, sometimes/frequently the FF would not start out in the right state (flopped instead of flipped) The set and reset inputs are too close in terms of how quickly they approach Vcc upon power-up.....
The charge rate of C3 upon power-up plays a role, when its changed to 0.01 uF, no problem.
Even at 0.1 uF, it still gave me that issue.
What was the purpose of it?
