nixie_tubes mod by Vanessa Ezekowitz
This mod provides a set of classic Nixie tubes, and a set of alphanumeric
15-segment tubes similar to Burroughs B-7971, controlled by Mesecons'
Digilines mod.
Simply place a tube, right-click it, and set a channel.
Then send a character or one of several control words to that channel from a
Mesecons Lua Controller and the tube will try to display it.
The classic tubes are numeric with colon and period symbols, and hence will
respond to the literal numbers 0-9, and the words "colon", "period", and
"off". Any other symbol or word is ignored.
The alphanumeric tubes respond to characters from the standard 7-bit ASCII
character set, along with these messages:
* "off", "colon" and "period" act the same as on the numeric tubes. Note that
neither a colon nor a period actually look all that great on a 15-segment
display, so use a classic tube for those, if you can.
* "del" or character code 127 displays an all-on square, but without segment
#15 (the bottom, chevron-shaped one).
* "allon" or character code 128 will display an all-on square, with segment
#15 lit also.
* "cursor" or character code 129 will display just segment 15.
Any unrecognized word or symbol outside the 32-129 range is ignored.
Tubes emit a small amount of light when displaying something.
