There is one other guy who built a clock, but as far as I know there are no details or schematics available. Here is his video: http://www.youtube.com/watch?v=ULKdAg0mLhQ > I would be most curious to know what their intended purpose was - why > would they design a display tube that had such odd power requirements. That has be baffled too. Mine even have a datecode from the year 1990, so regular 7-segment LED displays were already available for quite a while. > Perhaps on the plus side, is it's a high-voltage tube that can be > controlled directly with TTL logic (if I understand other references > I've read). Yes, that's correct (although I'm not sure about actual TTL levels, i.e. 2V = high). It certainly works great with 0V/5V CMOS levels. There is also the latching feature of the thyratrons, so you get the advantage of few pins needed for a large display without the disadvantages of actually multiplexing the tubes (flicker, reduced brightness, increased CPU load).
