Just build it in GaP and you'll have a solid state 'Neon' :-)
Neon bulb logic?
Kind of neat in that the logic state is visible. Hard to use for anything
more than simple circuits--aging and uniformity are real problems. I built
a couple of ring counters using them though.
Why not Shockley diodes? Anyone remember the Shockley demo of a diode-only
audio amplifier back in the 60's? Tunnel Diode logic?
Still got about a dozen of those things in my hellbox.
Cheers,
