Giant nixie panel from USSR

Once in Internet I found photos of giant soviet panel named IGG1 (ИГГ1). It was looking stunning!

This panel made in two versions:
IGG1–32x32 with 32x32 dots resolution
IGG1–64x64 with 64x64 dots resolution

Some technical data:
Brighntness: 150–300 kd\m2;
Minimal anode voltage: 210–240v;
Working voltage: 400v
Working voltage range: 370–420v
Current per dot: 25 uA;
Refresh frequency: 1000 Hz;
Maximum cathode duty cycle: 64;
Anode duty cycle: 32;
Dimensions: 193x193mm;
Weight: about 1 kilo.

64 version have two alternates dots colors: green and orange

Made at late 1980x — beginning 1990x at “Gazotron” factory (Rivne, Ukraine)

Today I got one IGG-64 for test. Maybe do some table clock with Wi-Fi sync:)
On photos it looks more smaller than in real life.

For convenience I've created a project page to log what I've found so far :

I’d love to know if you get this working too. I’d love to use one of these but the supply voltage is beyond my skills 😪

Can't read the Russian datasheet, and looking through the tech info on eBay I have a question. How do you select between the red and green colors for a pixel ??  Do the pixels alternate in color (red, green, red green, etc), such that you can only get 32 red and 32 green across or down ???  So that would make it a 32x32 for red or 32x32 for green, but not 64x64 for all red or green.....

Yes you're right, it is 64x64 pixels, but 2 times a 32x32 specific color matrix. Red (orange) and green alternate on a chessboard way

It is shown at the second page of the datasheet, I don't read Russian neither, but I searched green (зеленый) and red (красный) with google translate.

Thanks for confirming what I was thinking.

I think I start to have the idea of how the anode driver works:

Except the 10Kohm values visible on the video, the others resistor values are stupid guesses. 

When input (V1) is at 0v, Q2 is 'closed', charging C1 and Q1 is 'open'. So output is at 180v (~V2)
When input (V1) is at 5v, Q2 is open, Q1 is closed, putting C1 in series to the 180v, out is at 360v (~V2 + Vc1).

Transistors might be high voltage BJT NPN such as the MPSA42.

As I don't have yet these transistors, however I've tested 'manually' to charge a tiny capacitor (10nF) at 180v, then placed it in series with the 180v power supply and one anode. One cathode at ground. And yes, a pixel is flashing :)

These panels are inexpensive and available on eBay. I'd love to see you (or anyone else) get one up and running. The video @Muth linked to has a bit of a demo and the pixels have a really striking appearance!

The DIP packages should be shift register of some sort.

I don't know the types of the transistors, npn, pnp, fet or... So far I can only see something such as : 

I'm not enough advanced in this kind of electronic to really 'see' how it's working yet.

I found this video on youtube : 
Apparently it is possible to drive the anodes at 300-400V from a ~180V source, using a capacitor discharge.
I'm trying to figure out the schematics, not easy but doable.

Did you get this working? Just curious.

Unfotunatley no, I dont have time to have fun with it:(
