Hi
If I was to build an electronic visual computer, I would
use neon lights. All the logic functions can be done with
these and the results are visual. NE2's can be bought in bulk
for a few cents each.
I built a relay combination lock once but I used relays
and doides to cut down on the number of contacts needed.

You need SOME amplifier element; just logic alone would not do.
Neon lights for logic certainly would be possible, but neither convenient nor
reliable in my mind, since the difference between ignition voltage and burning
voltage
is not that big. Diodes are MUCH more convenient AND a lot less expensive
than Neon lights.
