Hello-

This isn't strictly a Nixie topic, but I saw a conversation about this in a
message thread in the Neonixie-L archives, circa 2002, so I hope it's OK.
  I have acquired some Beckman Berkeley decimal display units with the goal
of making a clock, and have so far been frustrated in my search for
datasheets and schematics.  A couple of list members made it sound like
they had copies, specifically for the 705AH/AJ/AK units.  Can anyone help
me out here?

Thanks in advance.

Robert,

I think I have a Beckman counter book at home. If not, my brother Jim, who frequents this list and had made a clock as you describe, certainly has some data.
