I picked up this chip to create a nixie clock:

501.html

it has tons of features which you can read about here (condensed feature
list):

IP/Neonixie-6-digit-nixie-clock-controller-options-v1.0.pdf

I picked up an old nixie time code reader display (systron donner) from a
surplus place (in seattle):

it was great because it had the nixies, controller chips, power supply and
everything. I just had to wire in the chip (prototype here):

final soldered version here:

and the final product here:

only problem is, it doesn't (yet) take a 1PPS input. I've contacted the
folks who made the chip to see if they would consider creating a version
with 1PPS.  But it does have a super cap that will let it keep time for
something like 8 hours.
