Yes I read the VTA article. Cant find it now but there was something showed up after a quick google showing the pinouts, is there just a backplane and segment connections as per an lcd, or is there other volatges req. And would I need to have any dc bias like on some vfd tubes to ensure the digits stay off.
It'll be interesting to see what happens JR, let me know what voltages, connections and resistors you end up with.
