The Magic Of Muxing!
Added 2024-04-02 19:36:25 +0000 UTCBack to the Packard Seven Segment Numitron Driver Board, this time to get it to do what it is designed to do - Multiplexing! Enjoy...

I suspect there are more than just diodes in that potted block. If I had designed this display, I would have put an inductor in series with each segment. Since the current through an inductor cannot change instantaneously, this would lessen the shock to the filament, and would help to make them last longer. But this is only speculation on my part.
