Giant nixies
 

I have Burroughs Giant nixies type B7971 used in early stock exchanges.
These come in a 17 pin socket with some hardware and transiostor drivers but
they can be bypassed to light the tubes. They give an alpha-numeric display
and are somewhat of a novelty. I have five of them with mounting boards. $8
each plus postage from Ottawa ON.
