    Was going to suggest that, trying to avoid more tedious soldering, but remember, then it's 'option base one' for the remaining viewable Neo's

    Also, . . . . One could run a long data wire from the last of those beneath each Nixie to where B6 was to control the in-between Neo's

    See note #27 where software SPI may not work
    'those based on nRF52 chips can have SPI on any pins'
