I have 6 Nixie tubes B7971 and a few MM5314 chips.

I have 5 HV drivers DS8880 but I think this is a multiplexed design which can't use this.

I would get the HV from rectified mains ~ 160 V for the HV side of the Nixies to make it as simple as possible.

Does anyone know of a schematic to help me build this clock with this chip?

How are the 7 segment Nixie tube displays decoded using? 74141 chips.

Thanks for the help.
