However, my understanding of neon logic is that it's great in theory, but
not
so much in practice. The characteristics between bulbs vary enough to make
implementation awkward and the characteristics of the bulbs vary over time,
leading to reliability problems.
As the description of ring counters in the the manual says:
"Lamps should be aged for best results and some selection may be
desirable."
Hi
At one time one could get three terminal neon lamps. These could be
used for many logic functions reliably since they always had on electrode
with ionized gas on it.
