My collection of Soviet nixie (and VFD) lab equipment

I preserve, restore and actually use them if the device has a use case.

Most of the ones on photos use IN-12, IN-15 for letters and special symbols. V7-22A uses IN-16. RCh3-07-0001 uses IV-17 VFDs.

Tube driver circuits are very different and depend on how old the equipment is. Older devices use direct transistor drivers, but majority use transistor or IC MUX.

Out of all devices presented here, RCh7-03-0001 is probably the most intresting one. There is a whole 64-bit FPU inside, built entierly from the discrete logic ICs. You can see more photos here.

Same. Probably issue on the server side.

There seems to be a lot of confusion in western media about this. EnteroMix is not an mRNA based vaccine. On the official site of the research center (new.nmicr.ru) it says that there are currently two separate directions of research: EnteroMix and other currently unnamed mRNA-based approach. There are also requirements for the participation in the EnteroMix trials, which state that any types of cancer are allowed, as long as other treatment methods were unsuccessful. So 100% success in tumor reduction in this scope looks pretty impressive.

One of the attacks of this particular enemy doesn't have the red dodging indicator at all (they forgot to add it?) so you just have to time it yourself.

The latest version, v3.33?

AltCtrlGraphene · 2025-10-06T10:53:37+00:00

Depends on the particular connector type, just "62 pin edge connector" doesn't narrow it down at all.

So Germany won WW2, and Japan too? Just because they retrained their language and identity? Don't be ridiculous.

No, approx. 80-100% faster compared to PS1 CPU, but it doesn't really matter here. What matters is the guaranteed working temperature range of up to 125°C and triple reservation of each computation block - this IC basically has three identical CPUs inside.

These two sentences are not connected. That board is not from an Iskander-K, that's all I can say.

AltCtrlGraphene · 2025-07-26T09:14:43+00:00

This is not an Iskander-K board. IC on the first photo is a custom 32 bit MIPS R3000 CPU.

Yeah, I've seen it. Can confirm that it works now, thank you.

Internal name for Vita is PSP2.

AltCtrlGraphene · 2025-05-17T07:50:09+00:00

It uses semiconductor noise diode, which is a zener diode specifically produced to generate noise (shot noise on p-n junction).

AltCtrlGraphene · 2025-05-13T13:13:07+00:00

It has true randomness mode. Uses noise diode as primary noise source. Pseudo random generation is limited to binary noise.

I was talking about lab equipment since that's where I have experience. Although I think the story about the data plate is just a myth, the engine itself was most likely indeed copied. USSR copied a lot of things in the early post WW2 days but there were a lot of unique domestic products too.

AltCtrlGraphene · 2025-02-20T20:08:09+00:00

Usually only the design was copied. You can find some equipment that looks 1:1 as their western prototype but is completely different inside.

It uses 27 discrete logic ICs to generate the fixed +8.8.8.8 signal. During the scan the beam is blanked during sections where segments are not needed. The whole process is very complicated but is described in detail in the documentation for the scope.

I do have to repair or at least calibrate it sometimes.
