Эту машину никто не стал восстанавливать по очень простой причине – её элементная база за время разработки, эксплуатации в 1976-1989 годах, и простоя до 1998-го успела устареть несколько раз подряд.
Компьютеры на индивидуальных транзисторах – писк моды в средине 1950-х годов. После появились гибридные микросборки с множественными транзисторами и пассивами, после первые микросхемы с единичными И/ИЛИ элементами, после серия К155 со сложной логикой, после микропроцессоры вроде КР580ВМ80, КР1810ВМ86, КА1847ВМ286, и т.д.
Каждое решение обходило предыдущее буквально на поколение.
Тем временем, этот K340A с исторической точки зрения может и интересен, но с практической… Когда есть своё государство, и его нужно защищать от вполне реальных противников здесь и сейчас – ни в какие ворота. По сути уже на начало 80-х годов эту машину можно было сдать на металлолом, заменив комнату со шкафами… На компьютер размером с чемодан.
Вообще, компьютеры немного теряют свой шарм – если почитать книжки о том как работают АЛУ, шины адреса/данных, декодер инструкций, и т.д. Понимаешь что оно не такое уж и волшебное – сейчас можно свои дизайны собрать на FPGA, экспериментировать, и т.д.
Будь документация и код – то и этот K340A можно было бы набросать в проектик, и запустить. И даже использовать для обороны, по назначению. 😉
When Russia ruled the planet! Today Russia should develop quantum computers instead of making war. Putin allone is so incredibly rich he could buy entire Switzerland, so he easily could invest just 1% of his money (he owns several Trillions of dollars and Euros and Rubles !) for building a factory making the best quantum computers in the world!
No doubt its programming language is LATIN.
I truly admire the immense effort and innovation that went into this groundbreaking project, especially considering the technological limitations and political challenges of the time.
A really fascinating machine. Sadly, in the soviet times, and to an extent in modern day russia, these advanced technologies were (and still mostly are) all made purely for military uses.
They could have done a lot, were such things built for civilian use.
But such is the sad reality in a country fanatically obsessed with improving it's military while ignoring everything else.
I sincerey hope you will have the chance to preserve what remains of this amazing machine one day.
I'm only 3 minutes in, and this is already one of the most interesting videos I've come across in years!
We, as HAM operators, weren't so happy with the woodpecker, it came so far, that all HAMs in the world were jamming the signal for three straight days. Which took it offline. So they got bombarded with jamming signals from all sides. The biggest event ever in the HAM community back in the day. We got even from the governments a yes, to use more power for this purpose, because they received so many complaints. I used a 9 element log per, at 38m height, with pure 1200w power, you can do the math in ERP radiation. And pushed as much harmonics as we could.
Could it play Tetris?
Why would you bother to learn a foreign language and just ignore pronunciation?
LEARN HOW TO PRONOUNCE W AND V!!!

Значительно более распространенное название системы остаточных классов – Residue Number System
В последние годы к ней вернулся интерес исследователей – ведутся попытки считать в СОК нейросетки.
Но проблема СОК все та же – модульные операции – сложение/вычитание и умножение делаются легко, а немодульные – деление или банальный для двоичной системы сдвиг влево/вправо – в СОК боль и страдание.
Книга Акушского 1968 года выпуска у меня лежит 🙂 Но в ней просто тьма математических ошибок. Видимо чтобы враг не догадался.
This is very well done. Very fascinating subject.
Я бачив багато схожих плат з своє життя, але вони стосувалися обчислювальної машини "МИР-1", наприклад… Дякую за цікаві відео! Щасти!
The amount of done work is huge. Thanks a lot for done work
A Pentium is more powerful than K340A. It is so fascinating, how people use to work with discrete transistors before ICs revolution. Great video !!
Thanks again for a wonderful episode. Once again another fascinating insight into the history of the exclusion zone. I really appreciate the time and effort you put into it researching these episodes. So sad to see the scrappers have done their damage in scavenging all the valuable parts (27:30 it appears that all the silver edge connectors on the PCB's have been removed/stolen 😞). Perhaps there are enough damaged boards left to reverse engineer at least one example of each type of board ? Are you allowed to collect any of these ? Maybe there are people who subscribe to this channel who may like to help out with this task in some way ?
Probably the most interesting video on YouTube in years.
Хай. Найс джоб. Аирплайн клок эс э таймер ис крайзи.
Is there any detailed information about that cooling system? Schematic looks really detailed but can't understand how it worked, with what refrigerant and what caused that water issue?
One option is that it was a water chiller system and the heat exchanger started to leak in the air duct.
Thank you for this incredibly well researched and detailed video – I always wondered how they did all the computing necessary to get any useful information out of the received signal. Just finished watching for a second time. This is probably not new for you but just in case: there is a video titled: "Duga – Nadajnik Lubecz-1 (unikatowe nagranie)" on YT that appears to show some sort of ceremony that was held at the transmitter site when it was decommissioned. If the timestamp of the video is correct, it was shot in May 1998. After the official part, some employees are shown at their former places of work: consoles, maintenance shop, laboratory, cafeteria etc. A lot of equipment is shown that looks very similar, especially those grey racks. The transmitter itself is also shown: In the video a corridor can be seen that contains what looks like many more or less standard shortwave transmitters one next to the other. When the guy with the camera climbs the antenna at a later time in the video, some 20 feedlines are visible connecting the array to the transmitter building. That would explain how the beam steering was done and how they achieved the very high pulse power. Maybe you can get some useful information from this.
such a shame it cant be rebuilt for historical legacy
This whole machine could be replicated by a fpga.
My dad's Mothers Sisters Husband worked on some army base that had a data center so when they were upgrading they were trowing out the older machines and i remember she showed me the cabinet and it was the same blue color as the duka compiuter but it was the sice of a small soviet refrigeraton and its current use is not far of as it now holds jams.
Only problem was that the system was pissing off a lot of Radio Hams and was named The Russian Woodpecker because of the racket it created on the bands.
I wold not wonder if the fake ferrite rods came from the factory. They could be intentionally made indistinguishable from the real ones when installed, so personal cold not no intrusively reverse engineer the software
Nonsense, this is a movie set from the movie "Divergent".
Kudos!
these archaic systems never stood a chance if the west deployed.
This fucking antenna ruined short wave during my whole amateur radio life. Rot in hell.
very interesting post.

Will you make a video about the entire high-frequency chain – from antennas to receivers/transmitters? I haven't found any information about this anywhere
Awesome research and production!
Just duga
Good luck with the project! History deserves to be remembered and preserved for future generations.
Very interesting and great video 🙂 I heard in another video about the DUGA system at Chernobyl 2, that it was in use until 1989, but I thought they evacuated the place in 1986. Did the guy making that other video maybe refer to the system in north-east Russia, or did they still use the system at Chernobyl 2, even after the accident? (I know you mentioned 1988 in this video, but got a bit confused, as I couldn't find any good information online)
This is such unique content. Well done. It's mind blowing for me as a computer engineer. I was wondering how the Duga computer worked for many, many years. I remember Duga's noises on my father's HF receiver when I was a kid. I hope times will change for you all soon. So you'll be able to create the museum that many would like to visit. It's an unique site with history which is part of the collective memory of every European raised in the 80's. It's well worth preserving what's left.
When I was there, there were still modules with core rope memory in them. Maybe you can still find some and do a video on reading them out…
Have never been so excited to watch a documentary about anything
Thank you for for yet another absolutely amazing foray into the history and technology of the greater Chornobyl area.
Nice video 🙂 I'm a former tactical electronic warfare drone with the Australian Navy, later the Defence Signals Directorate, radar was my entire life for a while. It does have some shortcomings though. OTH radar systems are like phrenology – if you work backwards, sometimes the predictions can match reality, the rest of the time is spent correlating results with other sensors in hopes you can improve the software as well as the state of the art in signal processing – it's a multi-decade long R&D project with no end in sight. Many governments keep throwing money at it, some have given up. Scroll through the HF bands and you'll hear these things spamming away 24/7. If your country has the ability to launch satellites, this is how they are solving the early warning problem.
knowledge I never knew I didn't have. thank you so much for this fascinating video!
Are there any plans to get that equipment into storage units so "tourists" and the elements don't degrade it further before you're able to restore it?
Very good feat. A thing worth preserving. My compliments.
