A clock using old and very rare nixie tubes to display time.

variants

I tried to decouple the main controller board from the tube board, so there is the possibility to use different tubes on the same controller board.

A short overview of the tube board versions and their compatability:

origin socket supported tubes
western germany Euro Grid ZM1000, ZM1000R
eastern germany B13D Z570M, Z573M, Z5730M, Z574M, Z5740M, ZM1080, ZM1082
russia RSH27 IN-8, IN-2
