A lot less common is the HP 1820-0092. There is a later version of that chip also called the 1820-0729. These nixie drivers do the same thing, a BCD to 10 output driver. The pinout is different than the Russian version.
It took a bit of research but I finally found the pinout and a truth table for this IC. The information comes from an HP 5321B frequency counter manual.

This is the information that I needed. I can now send the appropriate 1s and 0s via the 74HC595 chip to activate the correct digits.
