Hi dear reader ;-)
Some pictures would probably please your eyes, I hope you enjoy the sight !
It was quite some work but the result is nice. The only gotcha was a forgotten diode/segment in the decoder at NU2.A:

I reuse the same pinout and test board as the #Numitron Hexadecimal display module for convenience :-)
I'll have to do some "optical design" to prevent glare/reflections and keep the Numitrons readable, but this is for another time. As you see, I use a separate connector for modularity so I can design the front panel independently.
I'm already working on the condition display...
