I have taken some time off of the actual build to study this project but now starting to melt some solder again. The sequencer has now been mounted to the main frame and is working very well. I was having a problem with the J-K flip-flop toggling without error. It would hang up from time to time and freeze for a couple of clock cycles and then resume again. Just by chance, I installed a led to the output of the pulser circuit and not expecting to see anything due to the short duration of the pulse. I do get a nice flash from the led and now the J-K is toggling without any glitches :-) I can only surmise that the led is placing a slight load on the pulser circuit but beyond that I am open to thoughts about why it works better.

Here is the result so far. The pulser is at the top right with the pulsed led on the right side of the board. The toggled J-K is in the middle and the sequencer is at the bottom with five steps that I can branch from. Sorry for quality but cheap camera ;-)
