Nixie Tubes

Long before LCDs, 7-segment LEDs 7-segment filament , 7-segment vacuum fluorescent digital readout displays; there were Nixie Tubes. First appeared in the 1950s and used well into the 1970's for digital readouts of frequency counters, professional radio receivers and lab instruments. More recently for high-end retro digital clocks.

Most of recent supply are ex-USSR military, but now in recent years a very serious enthusiast is making his own. https://www.youtube.com/watch?v=wxL4ElboiuA

I remember in the late 1970s a school friend of mine picked up a working nixie tube calculator (something like the photo below) at a jumble sale for a few pence. He gutted it and used the case to build a Watford Electronics "Superboard" computer in. Sort of a shame because the original calculator would be a fun showpiece now!

Ah, the fun we used to have with high voltages before LEDs, like having to use magic eye indicators for simple level meters https://en.wikipedia.org/wiki/Magic_eye_tube
