I know it's off-topic a bit, but I stumbled on this clock using neon 
bulbs for counters and nixies for display.  No vacuum tubes--just 
caps, resistors, diodes and neon.

And here's the GE glow lamp applications guide that I referenced:

Note the sections on using glow lamps for logic and memory.


Cheers,
Chuck
