A clock using old and very rare nixie tubes to display time.
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:
|western germany||Euro Grid||ZM1000, ZM1000R|
|eastern germany||B13D||Z570M, Z573M, Z5730M, Z574M, Z5740M, ZM1080, ZM1082|
