First attempt to wire up the 300 Kg HDD of Chernobyl SKALA
Vložit

- Welcome to the continuation of our exploration of the Chernobyl SKALA computer system! This time, we'll look at a massive, nearly 300 kg Bulgarian ES-5061 hard disk drive and its accompanying portable test instrument, the TIDU-3P. This drive is the exact same type that was used in the DIIS system of the SKALA computer, as well as in the early "Shater" (Marquee) and "Finish" information systems of Chernobyl Reactor IV Sarcophagus.
We acquired the TIDU-3P briefcase quite accidentally, and it brought us to the idea of connecting it to the actual drive to see if we could make them work together. This led us to a computer museum for our first attempt at exploring whether it was possible or not.
What you will find in this episode:
00:00 - Intro
00:37 - Where were ES-5061 drives used?
01:58 - Some news

This has to be some of the best, most intensely nerdy content found on CZcams right now. It scratches an itch few things can.
Thank you for so motivating words!
On par with CuriousMarc and Usagi Electric!
@@KeritechElectronics wasn't it CuriousMarc that was getting an Apollo guidance computer working?
That's next level!
For someone like me who has worked on mainframes as a COBOL application programmer, this tech brings back memories. Still remember the old reel tape drives, then the compact square tapes that had to be mounted by operators, superceded by robotic tape silos, and then all of it was made redundant with virtual tape ie solid state memory.
300KG, with wheels, so it is easy to move -- until you drop a wheel into the hole in the raised floor under the drive, where all the cables went down under the floor. Then get two friends so the three of you can get it level again and moving again. Been there, done that. You DO NOT want to do that with a vertical tape drive!
Oh yeah. Oh yeaaaah. Thought about that while moving it.
For anyone who is interested in learning more about the history of Bulgaria's IT industry, I suggest Victor Petrov's book, "Balkan Cyberia: Cold War Computing, Bulgarian Modernization, and the Information Age behind the Iron Curtain" (MIT Press, 2023). The ebook is even available open access for free.
Oh, thank you!
Thank you for this information. This topic is really interesting!
Oh, I'm gonna have to look into that! I was considering following up my Radio-86RK kitbuild with a Galaksija repro kitbuild - Would make for some very nice supplemental reading!
A few years ago this same type of tester was up for sale here in Hungary on a local auction site. IIRC, the asking price was more than 100 000 HUF, which was rougly 400USD in 2018 (now it would be about $280 due to inflation).
HEY! I just checked, and it is still up for sale from the same seller, but now for just 30 000HUF / $85. It is claimed to be brand new (NOS). I just asked him if he has documentation for it.
EDIT: He answered, and unfortunately he has no documentation for it.
Thank you! Buy it out for any local museum. Because test instruments are all gone like at all, that can be a good addition to exhibitions.
Again, you succeed in providing unique and really interesting content! Thank you!
My pleasure!
Yes! _That's_ what's now no bigger than the palm of your hand these days (external drives), and CPUs (SoCs) are even smaller, and everything has anywhere from 100 to 1000 times the capacity, processing speed, and at a small fraction of the actual power consumption! Amazing how tech has changed in a tad less than 40 years!
Well said!
In fact a fingernail sized microSD working with 3.3V has billions order of magnitude more capacity than this 300kg cabinet, 3 phase powered cabinet.
But the people who have designed these ancient technologies paved the way for all of our digital living.
Allways respect ancien hardware.
At first sight, that looks a copy of a DEC removable hard disk: with RM03 (67MB)) or RM05 (256MB) packs even down to a DEC color scheme. In the west they would have been 70k$ back in the 1980s. The pull about 30A on spin up. If the heads crash, there is enough metal in the air that sometimes the next disk will crash too. As a summer student, I can tell you that they broke easily and the budget for maintaining them was enormous. Good times.
if only IT was then what it is now
Except for color, they are also nearly identical to IBM 360 era disk drives. Can't remember the model numbers anymore, but I think 2716 might have been one of them. I don't remember one pack crashing eating the adjacent packs much. In a good machine room with proper ventilation all the dust would have been pulled down under the floor. There were also air filters in the drive cabinet itself, and they would catch most all the dust. I do remember when long seeks would get these machines rocking, and one would start banging into the drive next to it, resulting in possible head crashes.
Hope everything goes well with the restorations. Thank You
This is a very unplanned project, as we got that TIDU briefcase accidentally; we'll see!
It's always exciting to see unique manufacturing electronic test kits.

29 megabytes was a lot of information for that era of solviet computer! Such beautiful technology.
It was made by motives of IBM machines, after all. That laser drive is interesting, that is 100 Mb.
@@ChernobylFamily When you say laser drive do you mean a WORM drive?
G’day from Melbourne Australia. I can’t wait to visit both of those museums, one day. (made a note!) I am awed by your projects, please keep going.
Thank you! They both are very interesting, and Chernobyl museum is truly one of a kind. Stay tuned - soon more!
It is beautiful, you're absolutely right. Thank you for continuing to take us on these fascinating trips through the looking-glass, to see the mysterious alternate world of Soviet-era computing!
Glad you enjoyed it
Man, I watched the printer video and that was cool as hell, now this? Subscribed.
Thank you! Check one about first Chernobyl robot recreation, and about SKALA. And many others. We have interesting things here.
The first hard drives I used were a slightly amaller size on a mini computer. The disks themselves were in sealed removable drums and had less platters than the ones in the video and came in 1Mb or 2Mb capacities IIRC.
Thank you for sharing!
Our school class visited a recycling centre in late 80's and I remember seeing these kind of huge cabinets on the massive junk metal pile. There were lot of those disk packs as well, at the time we did not know what they were. They were on their way to a machine that chopped them and spit out hot steaming balls of crushed metal.
Well, at that time this was yet not valuable historical stuff, unfortunately
in post USSR, people were making TV antennas from these disks, which looked like cheburashka
Yes!!!! I remember those vividly!!
Hi, thank You for another highly interesting footage about The SKALA! Friendsly greetings from CZ, stay safe, be healthy! ❤
Thank you! More to come!
Usagi Electric would be jealous for certain
:)
I would love to visit that Chernobyl museum in Kiev and that big open air museum of former Soviet passenger and military aircraft.
You are warmly welcome here. It is tough, you will need to react to air raid warnings, but we all are up and running.
Stay strong and safe❤
Excited to be here early!
Grab popcorn and take your seat in the cinema! :)
It smells like the cylinder address is sent as parallel, rather than the usual step and direction signals.
That would be rather flashy!
Need to check documentation to say something about this
Cool! Fascinating journey into the past. These great and intricate machines, so many different and individually engineered and laboriously assembled components. The labor and genious of hundreds. The aesthetic of those builds. Craftsmanship. Durability. Serviceability. And all that to store a few megabytes of data.
Glad you enjoyed it!
90 MB was HUGE. Probably from the mid 1980s. When I started working with computers, spinning packs like that had more like 5 MB, though pretty soon 20 MB became standard for the 5-disk packs, if I remember correctly.
@@lwilton our first hard drive, extremely costly upgrade for our 8086 PC, was less than 20MB
...
I really like the push button implementation. It allows both cleaning the contacts and adjustments to the pressure of the springs.
It gave a strange impression of being a reworked part of a relay. Just it looks oddly familiar.
@@ChernobylFamily Yes, like a relay or like a headphone jack with a switched contact.
Probably manufactured with existing tooling and materials well characterised by use in open frame relays.
@@ChernobylFamilyIn America those were known as "telephone switches". They were used by the telephone company as part of the switching equipment. Lever switches were more common than push buttons, but the internal workings were almost identical in both kinds. They were extremely reliable in both mechanical operation and electrical operation, and could be easily cleaned or adjusted when needed.
Thank you for those details!
Good luck guys! I'm always fascinated that such technology still exists. It warms my heart that you try to resurrect the system...
A tip: If you manage do do that, then the next project is a maket of the old control room of the duga radar :) Use Oled screens for the computers :D
Consider it as spoiler, but with duga radar we gonna have a working replica of certain equipment at some point...))
We used the HDD case as a bread basket back in 90s in our family, lol.
That is a lot of bread!
Looking at the inside of the briefcase it reminds me of an old guitar amp I used to have. Also from the early 1980s. Lots of space. Not a lot of stuff in said space. Very cool indeed.
Thank you:)
I live in Stara Zagora. Those drives are clones (exact copies) of memorex drives.
Cheers! If by the chance you know anyone who has documentation for ТИДУ-3П or -3М, we will very much appreciate it.
@@ChernobylFamily I'll see what I can do. But I'm not promising.
Thank you anyway, any contribution will help.
@@ChernobylFamily I can open sandacite.bg. I dont know whay you can't. Anyway here is the documentation.
drive.google.com/file/d/1Rov0zgC1YrxJnpSfHAPAnVgCz-gYUyWI/view?usp=sharing
@@ChernobylFamily I studied in the technical high school affiliated to the factory. My uncle was one of the head engineers - he passed away last year.
Most of the appartments had one or 2 of these hdd plates with a slot - used as tv antennae. :) DZU stara zagora was making all kinds of magnetic and optical (in the end) devices and media. I call around if i find something but i dobt any1 would have documentation left. If ot was before y2000 the chances would've been bigger
Nice to seen these two obscure pieces of technology reunited again since decades.
The museum seems to be a must sen for any nerd...
Hope you'll find the documentation and that there will be a follow up about this stuff.
Thank you! A few commenters found some documentation, we will work on it!
@@ChernobylFamily that's great. I love that people are still involved this way, and hapilly share their knowledge around a subject. Good old internet spirit here.
Amazing Tech! Thanks for sharing 🤗
Our pleasure! Check out other episodes!
As someone who worked with such computer disk drives in the 1970's I can say they need three phase power. And the disk in the drive is removable, weighs around 30 pounds, and only contains about 30 MB of data. The most important thing is to ensure the heads weren't damaged in transit otherwise that disk will squeal from contact as the data is destroyed.
Exactly, 3 phases 380V... we'll see if it is possible to get this input at museum. I am not sure if you checked that part where we review the packet itself, but it is correct - it is 29Mb.
@@ChernobylFamily In Australia the 3 phase was 410V and the 30MB was probably because of how they counted the Bytes here in the 1970's as in 1000 instead of 1024. Also we used 12 inch tape reels as storage and the disks were mainly for sorting and outputting the data to print. I wish you the best of luck with getting it running.
дуже дякую за видос :) рідко таке на ютубі знайдеш!
Дякуємо! Скоро додамо українські субтитри.
These old mainframe is amazing machine. Data almost see in hard disk surfaces :)
Check out our ES-1060 restoration project on Patreon!
Recently one of the engineers who developed these drive publish a book about the story around the factory and the economical impact. Unfortunately it is only in Bulgarian and available only as a paperback.
Both are ok for us, do you have the title? Thank you.
Good luck! I hope to visit some day.
Thank you!
Didn't know that Chernobyl used Bulgarian drives 🤯. Greetings from Bulgaria
From my experience, a vast majority of data centers used them (though Chernobyl NPP also uses German reel drives made by Zeiss Jena in DDR).
@@ChernobylFamily nowadays the only thing we manufacture is ракия 🥲
@@ChernobylFamily I sent you an email about the documentation for the tester :)
"Requires 3-phase 380 Volts AC..."
Dang, that thing would put my welding machine to shame when it comes to power consumption. I bet every light in the building dims when you fire up one of these units. And Holy Hard Drives, doesn't this thing put the "Hard" in HDD. What a beast!
But another awesome video. I so enjoy all these nerdy videos with such rare machines/ computers.
Why would it dim? It would likely consume way less than 2kW of power - less than your welder...
@@Sixta16
It's a figure of speech😅
I have no idea if something will come out of that, but if we will be able to, we will power it all up after 20 years of lethargy :)
@@ChernobylFamily
I truly wish I could be there when it spins up for the first time after all those years. These projects of yours are so incredible and awesome. A technical unicorn is a very good description indeed. The rare gems you keep unearthing^^
*Remembers how computers sounded back in the 80s
We'll see... it is not really a project, we got that thing accidentally, and the museum got interested... let's see where it will come :)
the most interesting computer video i've seen in yt!!!
Thank you! Check our previous episodes. You will open a portal to unknown. :)
absolutely amazing
Thank you!
In Ocident, the "high capacity" (10 or 20 MBytes) HHDs during 70s and beggining of 80s were not much different.
Wikid Awesome Guys!
Really cool stuff, that's a TON(s) of hardware lol
Thank you :)
Оце нахлинули спогади про дитинство.В мене батько працював у відділі АСУП ,завод ГМГУиА у Фастові . Памятаю як малим їздив до нього ,ці шкафи ,цей запах,шум.... що тут казати😢.

Перфокартами весь шкільний клас користувався)))
Чебурашки добре пам'ятаю...)
this disk was produced in Bulgaria, during Soviet times it was one of the first countries in the world to produce computers and computer technology, after all John Atanasov is Bulgarian and he is the father of the computer
Дуже цікаво ! Дякую ! :)
Будь ласка! Далі буде!
usagi electric would enjoy this, he loves his vintage US electronics from fhe 70s back,
Would be cool to make a collab, actually.
These are quite rare to find I actually have one of these it was a type used by Chernobyl but the one I have isent one that was in the plant it came from the Kursk power plant Wich still operates rbmk 1000 reactors
13:50 this is what caused resonance cascade last time
))))
I have (kinda drunk) idea. How awesome would be to create complex Chernobyl power plant management system emulator (with aproximation of reactor core functionality)? I know, that this would be too complex to recreate or even impossible due to lack of documentation. But still I think Idea is pretty good :)
There is an app, we will come to it. You can see it here on 11:30 - czcams.com/video/B2sjzxPBcO8/video.html
Are there any simulations of the "Promin" machine? I understand it was one of the first widely used computers to have microcoded logic.
This is a good question. I wonder if MAME emulator has it...
Hi! Thank you for your excellent job! I were wondering if I could find schemes showed in the video in full size without crops? I'm very interesting in it as a ex-DCS-engineer.
Thank you! You mean SKALA scheme? You can order it as a huge and beautiful poster - check the link to a public patreon post in the description of this video.
Interesting video and handsome man!

One must love the Lada doors. 😄
:)) that is a thing I prefer to see in a far distance...))
My father had a couple of Lada's in the 80's, and you really had to slam the door to get closed.
But those cars were cheap back then.
congratulations
Still a long road ahead...)
could it be that the ossi technology was a bit shabby???
A logic circuit (clock, 16-bit register 1,2,4,8..., function, mode and i/o switches). I have no idea how the sectors and files are allocated - which is pretty much everything on a hard disk (I somehow doubt it's FAT :)
Literally this morning we got a full technical description for the drive, which ALSO explains how to use the TIDU briefcase; I did not inspect it really much, but I see there is the information you are talking about as well it gives enough details to start the drive, will need to solder a few connector terminators though.
Back in 1950s... a 5 MB of hard drive, sized like a side-by-side 2 doors fridge. Even you need a forklift to carry it!! 😎😎
I believe you know that famous picture with a forklift and a drive...)
@@ChernobylFamily absolutely! The IBM 350
Привет из Болгарии. There is some documentation available for ТИДУ-3М. It is not much, but inside there is User manual, BOM and plenty of schematics - about 50 pages at all. I will be happy to share, please advise the method. P.S. sandacite website is up and running.
Thank you! Already got that file with the help of a few viewers. As for website, I have a feeling they have IP-based access blocking, because from many countries it just shows 403 Forbidden.
I always wondered if you can use the skala system as a computer, connect a graphics card to it and actually use it with an operating system. (Maybe sometime in the future)
No. It is too specialized to be a general-purpose computer, but a graphic interface for its specialized purpose is exactly what DIIS subsystem provides. It is not just a card though, it is a bridge to modern computers.
How can i send you the documentation for the TIDU-3M?
chornobylfamily@gmail.com
Thank you! However, a few commenters found it, though already. It seems it is good to understand the principle, but 3M version looks to be very different... if there would be a chance to find a 3P documentation, that would be something
The giant harddrive
Yeah
* SKALA/СКАЛА (ROCK/CLIFF) computer - Control System for Apparatus of Leningrad NPP - Система Контроля Аппарата Ленинградской АЭС
* ROCC - Reactor Operation Control Computer
According to the paper documentation it is SLIGHTLY different - "System of Control and Automation of Leningrad NPP", not "Apparatus"... (we were interested in that detail, so checked it physcially)
@@ChernobylFamily true. And thank you.
But ROCC sounds SICC, isn't it?
Yes
Man...As a hobbyist data technician/archivist with a _huge_ love of Soviet-era technology, I so wish I had hardware like this available to diagnose faults on my disks too! Does anybody know if Uzom ever did a version of these for IDE or even SATA devices? 😋
(And yes, I wish the devices I had were rugged enough to keep on working after a nuclear incident, too! 😇)
*IZOT
No, they ceased to exist in the 90-s... though the quality of their storage devices was very good compared to Soviet crap, so for retro-computing IZOT drives are a preferred choice.
@@ChernobylFamily The drive you're operating in this video certainly seems *very* well built, and made to last a literal lifetime. Better still - Because it's the disk-pack type - The media can be exchanged, so you just need the one unit plus storage for the media, as opposed to my collection of modern drives where every unit has its own controller, motor, head assembly etc... 👍
Granted; A 300Kg unit is probably a bit too big for consumer applications (Good luck getting one of those up the stairwell in my UK block of flats, or the floor safely bearing the weight! 🤣) but the flipside is my devices definitely won't last a 30-50 year lifespan. Recently had one fail on me that wasn't even a decade old! 😋
(Also; Looks like I need to vastly improve my Cyrillic on the side. Time to start studying the manuals I got with that Elektronika calculator... 😇)
Maravillosa y confiable ingeniería soviética
Except it is Bulgarian, not Soviet. Pure soviet drives were far from reliable.
Wired up like an analog circuit AKA the inside of a 1970/80's pinball machine.
Well, it is quite a "dumb" device, so it is pretty good comparison.
It looks like a copy f an IBM 70s main frame. The ICL system 4 was very similiar.In my time at ICl in the 70s I changes hundreds of those read write heads on disk packs.
Exactly, that's what I also said. ES series cloned IBM/360 and 370.
The East German ROBOTRON R300 was mainly built as a copy of the IBM System360. My dad was a service technician and installed and serviced some of these machines in different countries. I remember he fixed ferrite memory ring arrays at home. I built my first amplifiers with scrap parts from decommissioned tape and hard drive machines, some early portable disks drives looked like this in the video. Punched paper cards for data, punched paper strips for programming later ½ inch tape and theses disks drives like a washing machine. I remember he told me every country of the eastern hemisphere had a specific field they had to cover. Bulgaria was responsible for these hard disk drives and heads of magnetic tape machines. But CzechSlovakia I believe to remember was also involved with tape drives. I played my first computer game on one of those machines, which was actually a star treck battle game where you would try to avoid getting caught by Klingon and then should shoot them down with photonic torpedoes. No real graphics, only characters used to make a graphical appearance. The other game was the board game GO.
What is format of TIDU PCBs is it standard?
They feel like 11x7 cm (need to disassembleto measure), so they are more than twice as smaller compared to standard TEZ cards of ES EVM. Personally, we did not see that small cards like in TIDU in ES equipment; but they are nevertheless marked in the standard way.
Well, one Sinclair Microdrive (external drive for ZX Spectrum) had 100kB.
100kB was just what they were aiming for in the early development stage. When they were delivered it said minimum 85kB. I remember typically it was 88kB. If you pressed the cartridge into the Microdrive while formatting, you might get 92kB but you would probably always need to hold it press it in to be able to use it like that, so not recommended!
I expect pressing the cartridge in just pressed the tape harder against the tape head, creating more friction, so it took a bit longer for the tape loop to go around.
At this rate, you’ll fix the entire reactor core, and the plant will be entirely functional again! 😂
Also, is it possible there is still any data on the drive? If there is it would be amazing to be able to recover it, and examine it!
:))
These disks are god know from where, but maybe really there is something. We will see.
How come the museum pieces are sealed shut?
They are work pulls from a functional ES machine which was based in Kyiv, and was scheduled for a permanent shut down in around 1995.
Hi I saw the trademark "ИЗОТ" - I suspect a Bulgarian link here :)
Yess
Sexy is when it's working. Good job so far.
Thank you!
BTW, there actually are some people who think Ladas are cool cars, it's like a sick cult.
True.
What is the reason for the seals on the boards?
Serviced, tested, confirmed operation by manufacturer or service center. Similar to any product - varranty void if removed. Just they did not seal entire device as to connect cables you must open the rear cover.
Now, those seals already is a museum issue; because if item is in museum, it must not be altered.

Again, a fascinating look into the Soviet / COMECON computer tech! And a beautifully made piece of test equipment. I love these bitbanging switches.
I've got a bunch of germanium DTL boards recovered from e-waste, with MLT resistors, mostly USSR made semiconductors and markings in Cyrillic. They may have been made for the early unified series computers, but I'm not sure. You might find them familiar.
czcams.com/video/Bjyzd0HevTA/video.html
Those are not ES, I am sure, this is something earlier than 70-s, element base and overall design is greatly different from ES standard. It is more a style of e. g. MIR or MINSK machines.
ES boards (so called TEZ - standartized exchangeable elements) always have a unified form-factor of 140х150 mm and have either lamellae for corresponding type RPPM connector on a backplane, or in case of later 1060 and greater machines - SNP-135 connector (female on a TEZ and male on a backplane). They also must have an inscription ES-xxxx or EST-xxxx on them.
@@ChernobylFamily thanks a million! That's one step closer to solving the mystery :)
id like to see the rom and the ram
It might be so simple as to not have either, or if it does have anything like a ROM or RAM, it'd just be like, lookup tables for logic and flip flops/registers for some state.

Your English is very good but of course you have a little bit of an accent which can be a little difficult for some people to understand, especially lazy Americans. I respectfully suggest that the addition of background music makes it even more difficult to understand any dialogue, even when the dialogue is spoken in one's native language. The saturation of the audio with a fast-paced techno background music beat is very common on CZcams, but is very annoying for some of us. Thanks for considering this suggestion!
Thank you, a known issue - noted for future! Just saying, there are subtitles available.
