The ARM is in control.

I soldered up a stock PNP-NPN transistor tree for the anode control, and surprise, it worked first go. This was reassuring as it is the first time the ts7260 has been hooked up to the high voltage.

The next step is to replicate that a further three times, and then wire up the nixies. Board layout is the toughest part of this project, I am geometrically weak.
