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?

Still got about a dozen of those things in my hellbox.
