You would tie the decimal point to a positive supply (like the other
segments) thru a larger resistor. I would start with a resistor value 10x
higher than the series resistor on the segments.
To prevent wearout, use the lowest current that gives acceptable
illumination.
I didn't see anything
I know IN-12B Nixies the decimal place need an additional resistor on the
decimal place (usually ~22k, 1/4W from memory)
Do IV-22 VFDs require something similar for their decimal place - if so
what's a good value compared to the other segments?

You can also have decontrons do the counting:

I'm guessing some more parts can be replaced with tubes by replacing the
rectifier with a tube rectifier.

Do you have a link to the assembly manual? I have the clock, just not the
manual.

i know this is an old pose but i have some 22v10's, what kind of stuff have
you made with them? using one as a bargraph driver or shift register woud
be nice for my projects since i have some neon clock displays and uusing
one to multiples it would be cool, its an old gold ceramic 22v10, but
