More curiously, here in Croatia- in fact all countries of former Yugoslavia, generic term for all electronic calculators was and still is digitron. Name came from a factory Digitron in Buje, Croatia, which made all kinds of desk and office calculators. Their products could be found on each office desk around the country and name stuck. Anyone knows who originally coined Digitron name? Tomislav Sent from my mobile device

Also VFD tubes are reffered as* itron*.
