Created a PCB and sent it to OSH Park.
As I usually do, just put the footprints right into the layout and quickly clicked to connect the netlist like me scribbled schematic.
I also brought almost all the signals to 8 pin headers which will mate with a Saleae logic analyzer. Long ago, when I had more time, I probably would have prototyped this on a breadboard or vector board with point-to-point soldering. But that takes a lot of time to build. Took only an hour to quickly connect up all the parts on this PCB.
Of course with a PCB there's a long wait. I also chose postal shipping on a Digikey order for the 74LVC chips. Going to put this all aside until the PCB and parts show up.
