Okay - my typical format in reverse - rather than starting out showing you the display running and then going for a teardown, I have to do this one in reverse and take it apart first. And then it gets interesting..... Enjoy!

примерно в 1980 году в мои руки попал цифровой индикатор, который состоял из 10 ламп накаливания, 10 цифровых шаблонов, 10- линз и матового экрана
Have you tried connecting the socket with the wires directly to the one with the bulbs? From here it seems like it will work that way …
На лампочках!!!!!😮
Во раньше заморачивались! Такой бутерброд собрали!
lol, all gold plated pins…the federal government knows no bounds…in making solid gold hammers.
That thing had to be ridiculously expensive when it was new
Fascinating device! What a huge amount of complexity for a single digit.
Question; can you pull the front-most part out of that to change the incandescent lamps without removing the rest of that from the panel?
wow, I just wander how would they manufacture those mini bulbs? it just looks impossible
Now you have it apart, you can bypass the driver and just power the first half of the display 😊
Nice! 4 bit latch — 3 bits for 7-segment decoder, one bit for decimal point.
The opposite of module replacement – you can replace every single component. Just imagine you are on Mars and can't get a new module. It's enough to have the proper incndescent bulb and your display is good to go again… crazy.
Super! Thank you very much!
It must have been designed for the military. It looks too expensive for commercial sale.
two TTL like 7447… the 5447 is a military version.
Really disappointed you didn't get it going.
Would be a great video to see you reverse engineer the pinout and get it running.
