Cool video, it would be interesting if you could do a video maybe including the amplifiers and systems of de rader it self!

Probably all 160 IQ + guys designs 😅

I've seen an old swedish optoelectric tape reader that could read 3000 octets per second.

At the time it was operating, people listened to Radio Luxemburg on the AM band, then this started to fuck around, and was known as the woodpecker, And it was known that it emitted 32 bit digital signals and used the backreflection to calculate where a target was at..

Haszontalan baromság, amit feleslegesen építettek és rengeteg pénzt költöttek el rá.

I don’t even know what to say. 😢

Сложить "пазл" и получится, что катастрофа на Чернобыльской АЭС это диверсия для выведения из строя объекта Дуга.

Still neat and clean

I'm so glad you are saving all these computers! They deserved to be preserved

did USA have anything like Duga radar?

That must have been such a surreal and bittersweet experience for engineer George, seeing "his" finely made systems in a state of derelict abandonment. The lifecycle of facility scale tech is so short that the people that make it will probably outlive their creation by at least 2 or 3 fold, but the material is so valuable it's almost never abandoned in place and left to the elements for long. Wonder if Uncle Sam had anything to do with those pencil cores showing up in the batch of ferrites. Letting it go on for weeks is much more on the sabotage end of things and would get the perpetrator fired at most companies...in the USSR I'd imagine that "firing" could be a lot more literal.

Do you have information about how the RF system works in that facility? Regards

Like if you actually visited the site as a tourist (I was there in 2017) 👇

I still want to load up the antenna array for contest weekend on 20m. 😅

Прекрасна робота і матеріал. Як то кажуть, це вам не за бордюри взимку триматись, коли слизько під ногами :)

These older machines have really nice looking motherboards 13:19 I love that yellow board. It’s so cool looking.

I am out here in Poland. Man it would be so cool to go there and check out these machines you have. I guess it’s all in a museum?

Beautiful panel. Too bad so much of many of these machines were scrapped.

Ooh nice can’t wait, but have to go shopping, paused back later

Woody woodpecker.............mwahahamwahahmwahaha!

When I see computers like this I am always in awe. Nowadays some programmers have difficulty in grasping pointer to pointer concept, but there were people who not only did much more difficult operations on those computers, but envisioned and designed them.

incredible work. we used to monitor the system and called it the Woodpecker, the noise it made interfered with communications, it crawled up and down the HF (2-30Mhz) shortwave bands. OTHR Over The Horizon Radar in its infancy and ionosounding for propagation calculations. A great credit to all who worked on it in the very early days of digital signal processing.With suitable antennas and transmitters/receivers all of this can be processed in a small desktop box or two Thank you so much for this project. Maybe Chernobils SKALA control systems were upset by high levels of RF EMI/ EMC from the antenna and kaputted Chernobyl well someone could have reversed the phase of the elements so it "pointed" at Chernobil a few km away??

It shows once more that Russia was far behind other countries.. in the 80´s these computers were nothing but old junk

Sorry, but I had similar case with 80486DX2 PC motherboard by "Квазар-Мікро", but scrapped it in 2007 (because it was broken, not functioned)... Such two side riser card with ISA+PCI, so not so compartible with other motherboards as here. Very robust and hard device it was.

Bell, we got a job to do

Looks like an IBM 360 console.

This reminds me of the Semi-Automated Ground Environment (SAGE) story. SAGE was a network of huge computers that coordinated the air defenses of the US, operating long after its vacuum tube computers were obsolete.

It's sad that they lied to people about the evacuation being temporary. Hopefully some saw through the lies and saved family heirlooms.

The rocket boys gave the radar boys incorrect data about plumes. The radar guys took it on faith and assumed it was true. It wasn't. They designed an entire gigantic radar system based on those false assumptions. IF ever there was a case for pushing someone out a window it was then.

Clone of the Toshiba T1000 or T1200?

I think after wiring it up to arduino, you can play tetris on it! ❤

A OTHR that required regular frequency changes depending on atmospheric conditions due to changes within the F layers. The interesting part is how the returned signal is processed.

I know I'm late, but you could make a control panel, like add some metal, add buttons and make it be a control panel. And after thats done, you could make a diy version of Joker or one of those robots since your robot build was REALLY accurate and amazing looking. Then control the robot using this

Эту машину не стали восстанавливать по 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 средины 1950-х годов. После появились толстоплёночные и тонкоплёночные гибридные микросборки, 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 здесь и сейчас от вполне реальных противников - то ни в какие ворота. По сути уже на начало 80-х 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. :)

The powerful airflow serves to keep the inside of the disk clean. It also created a flow under the read / write heads. The heads had an aerodynamic shape. The airflow generated by the fan and that generated by the strong rotation of the disk, kept the heads raised a few microns from the surface of the disk. If the filter was dirty and the airflow was not sufficient the heads "landed" on the disk and you had to throw everything away. I have repaired many copies in the original version. Control data corporation. They were spectacular. We called them "washing machines".. hello from Italy🇮🇹.

I HAVE A QUESTION ! SO BASICALLY SKALA CAN DO POSSIBILITIES OF WHAT HAPPENING IF THIS THING IS GOING ON ? HUH ? LIKE IF REACTION GO OUT OF HAND ! SKALA CAN DO A KIND OF FUTURE PREDICTION?

The Soviet HAARP

imagine back then, they have today's technology. This video, is amazing. 👍👍👍

I've always wondered about the electronics that attached to the duga array... If possible can you explain how the RF portions of the array worked? .. like what equipment existed between the array and the computer. - Thanks for the great video!

I've seen some videos looking at the antenna array, but it's cool to see some of the history of the computer that processed the signal data. I worked at a company that created a simulator of the reactor at Chornobyl, and the owner added a lot of information on the history of that project. It's too bad Chornobyl has caused so much fear of using modern nuclear power with fail-safe designs. We need nuclear power plants if we ever want to reduce the burning of hydrocarbon.

What a strange, fascinating machine! Hopefully, some day you will find more complete documentation surviving somewhere public. Since you mentioned patents, I wonder if the patent filings would have any useful information on how such computers operated? Or, is that part already publicly available elsewhere? Sometimes, patent documents are sufficiently detailed to yield useful clues to the thinking behind the devices they patented. I've never had a reason to request such documentation myself, but I know that others have done so for research purposes. In any case, good luck with your research!

But can it play Crysis?

I can remember at Philips Semiconductors there was research into using Residue Number Systems for DSP.. It was dropped because it transforms multiplication into modulus addition of residues.. but made the operation of adding two numbers into a more complex operation than a multiplication in straight binary. That required to decode to binary, add and then re encode into RNS form.

Too bad I can't lay my hands on one of those rack cards with transistors... it would be nice to analyze one from close up, although I suspect very little actual information could be "distilled" from a single card .... but as you say, the war changed the situation. Let's hope for a positive outcome in the near future Slava Ukraini

Super interesting! So they felt it was ineffective, still they used it for a long time poluting hf-bands with the woodpecker interference all over the world. I remember we used to put out short fast "dit's" with a cw-keyer radioequipment on our local radio club with around 1.5 Kw output and a big yagi antenna pointed towards it, just to interfere back hahahaha

Fascinating!

Fascinating!

Great channel
