The radio station I worked in in the early 1970's at a Nixie based clock as part of a program automation system. The Nixie tubes lasted forever, but the driver chips would fail constantly. Handling that high voltage seemed to be a problem. Speaking of old technology, anyone remember the (RCA, I think) Numitron display? It was a seven segment display using incandescent filaments. You could use them just like an LED seven segment, but could not multiplex them without adding a bunch of diodes.
