The "Numitron" tube was developed by RCA in the 60's or 70's as a low voltage replacement for a "Nixie". It uses 20 volts on the digit anodes (works well @ 12 V.. in my direct experience) has a filament tat must be powered (1.5 - 6 Volts @ 100 - 500mA) depends on the spec for the part. I am not familiar with the Russian IV series however the principles are the same... It would take a great deal of work to interface it with a MAX7219. I used CD4017's as decade counters and drove the digit anodes with 2N3906's from the 1 of 10 outputs of the CD4017. The actual details are somewhat... as I did this thing in my 20's and I am nearly 66 years old now. The point is that there is one wire for each "number/value' and not easily done for a 7 segment decoder/driver like the '7219. Supply voltages are different (the CD series had a max voltage of 18V and Spec'd at 15 Volts, making them a great choice for decade counters... in another similar project I used 7442's (bcd to decimal) and mux'd them, 8 data lines 4 for digit data and 4 for addressing a digit counter/latch. All Most Old School and questionable here except as a beginning to interfacing the IV series of displays
I think you mixed up VFD's and Numitrons... Numitrons is just a 7-segment display with incandescent wire as the segments.
