I love the way you say "mechanism", the -ch phoneme sounds the same as in Scots and German :) Though most Scots only use it when speaking Scots, or when using Scots words mixed-in with English speech; so they'd use it when saying words like loch, or for instance with the phrase "mechty me!" instead of the English "oh, my god!" A lot like Norwegian, Danish, and Swedish or with Ukrainian and Russian, Scots is its own language that just shares a common ancestry with Modern English. Specifically it's an offshoot of when Scottish Gaelic mingled with Old English and Middle English, hundreds of years before Modern English arose. So it never had the Great Vowel Shift for instance! Though it's a common attitude in England (or among English people living in Scotland) to believe Scots is "just mangled English" and "isn't even really a language", sadly. I know some Russians also hold that sentiment about Ukrainian, but I don't know if it's as widespread an attitude (though I sadly expect it probably is, or even stronger). The ending is crying-out for a paper tape re-spooling machine! I also found the 6-bit tape thing interesting, I haven't seen that among western vintage electronics. Usually even the 6-bit word length machines used the 8-bit wide tape, just with the two left-most holes left empty (so 5-3 becomes 3-3). I guess the narrower tape was just... to save paper? I think the wider tape was kept over here so you couldn't accidentally put it on upside down.
Thanks about note on language, that was interesting! I used to guide in the Zone and had Scots many times, so remember their way of speaking vividly. Can't say it was a problem for me, though :) I am no sure, but didnt PDP machines use 6-bit tape? As for narrower tape, I believe that might work for CNCs. Those often used PL-150Ms for their programs.
@@ChernobylFamily yes, the PDP-8 with its 12-bit word length used only 6 bits, but all the photos I could find of actual software for them showed they used the wider tape and just left 2 columns un-punched! Then 2 rows would be combined to get the necessary 12-bit words. Usually with one address word followed by one data word, so every basic data “item” would use 4 rows in most programs and such. And then the same paper tape machines were seemingly compatible with the PDP-11 with its 16-bit structure, and could use all 8 columns. But I couldn’t find that for sure unlike the PDP-8 and 11 tape formats, so perhaps Digital swapped the readers as well. I’m not surprised you got on fine with Scots, I notice most northern and eastern Europeans actually have an easier time with it than Modern English! Largely it seems because the vowel shift which occurred in early-Modern English didn’t occur in Scots, just like it never did in most other Germanic(-ish) languages.

I was made in Belfast Northern Ireland at the start of the Sixties. We lived near a big ICL factory and I passed it running errands to the grocery shop. There was a little park area with seats and litter bins which were nearly always filled with many metres of pink punched paper tape. I remember wondering why the tape was being dumped outside and not in the bins of the factory. Could it be there was a programmer who was very embarrassed about making a lot of mistakes and sneaked the tape away to dump outside? I guess we'll never know... Brilliant video folks, I really enjoyed watching.
This reminded me on a little episode from my childhood: it was 1992 and I remember we could find these tapes everywhere. We were little and did not know the real purpose of them until parents explained. That year, mainframes were slaughtered en masse, and we have been playing with these papers - they were flying beautifully.
@@ChernobylFamily I should also tell you that when I did physics research at Queen's University Belfast from 1997 to 2000, I found boxes of old Fortran punch cards but bizarrely they were cards with maybe only two or three holes. Usually they can have maybe a hundred holes. It turned out that my supervisor and the building manager saved the cards from thirty years before because they were just a nice size for writing notes on. They were from a generation that hated to waste things - both gone now I'm very sorry to say.

Very interesting video! I'm also motivated by your passion on making forgotten technologies live again. Coincidentally, I also acquired a Chinese made tape punch/read/check device, with concept similar to your one. It has 5/8 bit tape punch, photoelectric tape reader and a keyboard. The unit is electronically controlled, not like other teletypes such as ASR-33. The punch/read/keyboard unit I have weights 17kg but the control unit which I'm missing should weight more than 30kg according to the information I've found! Just like you, I'm also planning to make a modern interface for my machine. I'm planning to add UART capability(which is a must have) and also USB keyboard emulation, so I can use the machine as a convenient input device on modern computers. I think with your tape punch restored, you can make some customized tapes and seal them in plastic, for sale as bookmarks. They should be very welcomed and should add a little help for funding your bigger projects.
A few (!) years ago, when I was in college, we used the Teletype ASR-33 punch tape terminal to keep our programs between semesters, when they wiped the drives.
Now here's an interesting bit of Venn Diagram overlap between myself and you guys - during the 1990s (the late 1990s, I might add) I had a job with an electronic funds transactor company here in the US called (at the time) STAR Systems, and our main central processing system was comprised of an IBM S390; I would wager the JCL we coded in would run quite handily on some of the machines you've talked about in this very video.
Thank you for a story! Yes, actually a lot of western software would run on ES. In reality, a lot of original IBM-compatible software was stolen/cloned and reworked, surprisingly even often improved with bugfixes ;)
I’m really impressed! I’m sure with an Arduino or a Cheap ESP8266/32 you could get some sort of communication going with the unit, it would be kind of impressive to make one of these wifi or Bluetooth enabled (maybe make it emulate a keyboard of some sort to get data out of the tape and give it some sort of web UI that translates text files back to binary) just to say you did it! Really excited to see where things go with that control panel too, it looks challenging but would be very rewarding to have a working model going for historical reference.
These PL-150M and FS-1501 outlived their mainframes, as they were used for CNCs, and in some oldschool workshops they are still being used. So there are superrare industrial ISA boards for them, but also there are at least two circuits developed already - one on a simple logic with COM port communication and a DOS program, and more modern one on a microcontroller, also for a COM port. That or another we will try. At least, we'd like to make cool merch - a tape with a custom message :)
@@ChernobylFamily If you get ahold of one of those ISA cards - you can most likely use them on modern computers since ISA is still kinda exposed on the tpm header (isa to lpc chip needed tough) Would be funny to see that old hardware and software working on something modern :D
@@_DSch very much hoping for that. Yeaterday we have visited the Polytechnic Museum in Kyiv, they have both PL150M and FS-1501 and they are VERY much interested to get some adapter as well.
Vey cool that the speed adjustment makes one gear larger and the other smaller so the relation is changed but the belt size don't need to change. Cool!
Hey guys, I think the switches used for synchronisation are called "Hall effect sensors". They are triggered when there are changes to the magnetic field, in this case caused by the little magnet on the inner wheel spinning past. By the way, this episode was very nicely put together: The little montage while powering the machine up, and the extra information about how punch tape works were great additions. -Dominic
I doubt they'd have bothered with full Hall effect. More probably, they'd been reed switches. In Soviet literature, these are often called 'hercon' or 'gercon', 'херкон' or 'геркон'. It's supposed to be short for 'HERmetically enclosed CONtact; spelling it with leading 'h' is the Ukrainian way, and with leading 'g', the Russian way.
In Ukrainian we spell it also gerkon, but you are right, it is not ringing G, it is much softer :) Mmmm I can't recall that small gerkons, will ask my mate who has full schematics for PL150M.
A Hall effect sensor is a solid state device. This looks like a magnetic coil. I'm not aware of any name for it, beside "pick up coil". It would work on a principle similar to an electric guitar pickup.
@@russellhltn1396 You could be right, as a pickup would certainly be cheaper... But my understanding is that the signal from a pickup is a sine wave, while a Hall Effect sensor is a square wave. If you're actuating a punch with exact digital (serial) timing, wouldn't a square wave be more easily applicable without modification of the signal?
Those 3 "switches" that look like coils on the end of the motor are in fact HAL sensors. They send a pulse to the control board to control the speed of the motor or to "inform" the current speed of the motor for it to punch at precise timing.
Had a computer pair given to me that had ttl memory of 4k (1 card had 1k on a size of 9 x12 card) its companion was set up as a paper tape reader /punch unit. Called super smart and super dart
It was HAL sensors used fo synchro, or kind of. That's really neat suff, the analog beginnings of digital age. I love this machinery. So if You don't mind I would like to join the family. Especially as born right behind west border same year as Czarnobyl's big bang🤯
You warmly welcome! As for this video, please check our documentary about SKALA computer that used this tape punch- we put a lot of love in it, and we hope you will like it!
Hi Guys, great to see you recovered that mainframe panel. I'm looking forward to seeing it restored. All of the kit, is deeply cool. I remember being reading about punch tape but never got to use it. The box for punch tape has got a nice design. Needs a good clean.
We already made some shopping with the help of patreon, so soon will be some updates on the first cabling work... that is going to be a long journey. As for the punch... heh, it was green, needed to retrobright it to return the blue color. However a few spots on the top we are unable to clean out with anything...:)
I was taught the basics of punch tape at Institute of Technology as late as in late nineties, if only to preserve the CNC code on a more modern media (like 3.5" disks or other marvels of cutting edge technology...) Machine shops tend to keep useful hardware around and running as long as possible. And when it's no longer useful, you know it's absolutely *ancient*.
I worked in the former Czechoslovakia as an EC-1033 and EC-1045 operator😉 We called devices for 2-36mb disks "washing machines" because they visually resembled them😁😁I was still young at the time.
Oh my... Look, we VERY much ask you, if possible: can you write us an email using a 'contact us' on 'about' page of our channel? The thing is, EC1033 was installed at the upper floor of the Duga datacenter, and we crucially will need a consultation of the actual operator of such a machine.
@@ChernobylFamily As an former operator, I probably can't help you with technical matters, the technicians and programmers who took care of the system and repair of boards could do that, although some are still alive, but they are people 70+ and I have no contact with them.
@@ChernobylFamily Yes, but this operation of the front panel was in charge only of technicians who turned on the whole device and knew what each indicator light meant! They had a manual for it At least in our case, the operators were not allowed to do anything on this panel, at most turn it off or report that something is wrong. And the diagnostics were carried out by technicians! This means that the error messages diagnosed by the lights were managed only by them. Most of the time, there was a problem with some board and they had to remeasure it and resolder the "cockroaches".So unfortunately it cannot serve😌
Hey, greetings from another lab coat wearing nerd gal with Slavic origins :). Nice unit! I love how it's built, contrary to Allied computers, it's more mechanics than electronics, all so simple and reliable. Cool that you show synchros, as CuriousMarc just did a video on them :).
Of course I will do, but with this equipment the only people who really know something are Chornobyl NPP engineers. We had a few meetings with them, so at some point there will be a really massive episode about unique tech.
Chernobyl Family, thank you for that video. It brought back many memories for me. I am waiting for your video on that Скала machine. I've read thousands of articles for Chernobyl disaster and I know that Скала was important part from reactor equipment. It will be very interesting for me to see what that piece of machinery was, what was the purpose of all that racks and control boards and lamps and switches. Was it a real computer, how it works. How many programs run on it. What was the operating system. What is program Дрег and how this program takes the measurements of the parameters of RBMK reactor. Please do that video.
Thank you for your motivating words! We will make it as soon as it will be possible. Right now there are severe limitations due to the wartime. However, it is highly possible that we will have a few episodes about its components again before the big one, specifically, about DREG.
I love your humor. Good luck with your extensive restoration work, which may be laborious! * J'adore votre humour. Bon succès pour votre vaste travail de restauration qui risque d'être laborieux !
@@ChernobylFamily Bonjour à vous deux, ❣ "Humor is the politeness of despair." In France too, and especially at the moment. * "L'humour est la politesse du désespoir." En France aussi, et surtout en ce moment.
8:58 Those look like "variable reluctance" pickups. The pointy bit on the rotating bit changes the reluctance of the magnetic circuit for the pickup (coil) as it goes past, and it gives an electrical impulse.
Yeah, the same as the pickups used in electric guitars, and sensors on cars such as camshaft and crankshaft position sensors, and anti-lock brake sensors, I dismantled an ABS sensor last year, and was stunned at how much tiny fine wire they'd crammed in there wrapped tightly around the soft iron core.
I remeber these from Czechoslovak embassy in Baghdad. There it has been used for storage telex data before decryption in another machine. That was back in 1989 so I can confirm it was used probably also in the early 90's. Anyway, thank You for another nice video as always.

When i was at school some of our first programs were punched on paper tape.... i wish i had kept them... paper tape is the ultimate symbol of retrocomputing.
Great video ! Happy to see you both :) Možná byste mohli vědět, nenapadá mě nikdo povolanější, protože to vypadá, že o Duga radaru víte hodně, zkoušel jsem hledat bezvýsledně na internetu, jaké se používaly elektronky v RF části duga radaru ? Nikde jsem tuto informaci nenašel. Looking forward to the next part, punching some code !
Dobrý deň, presne nemôžme povedať - nakoľko zariadenia spracujúce signál sa nezachovali. Logicky - elektrónky by mali byť použité len vo vysielacej časti Dugy, ktorá sa nachádza v Ľubeči 1. Toto miesto nie je prístupné. Existovala celá séria elektrónok, generujucich signál, nazývali sa GU(ГУ) a nejaké čìsla za tým, veľmi silné boli napr. ГУ-23. Možno mali aj niečo silnejšie
That's similar to modern IBM mainframe computers. In its operation system, there are still punched cards readers and writers as virtual entities with some very practical purposes
Love your work! I invented (well, at least I never heard this before) the concept of "Industrial Archeologist" for folks like yourself who resurrect old industrial technologies. I'm from the US, and would love some day to visit Russia and see your marvelous restorations in person.
Dear friend, although we appreciate your words, I advice to pay attention to a flag of which country is near our channel name. We are from Ukraine. We. Are. Not. Russian. From russia we have just missiles and drones falling from the sky while we edit those videos (happened literally this way a few times).
@@ChernobylFamily Sorry to hear that, and sorry about your situation which sadly, could easily have been solved peacefully by adherence to the Minsk agreements. In any case, stay safe.
Thee name of the device is synchro. It was used in old planes and machine to sense position think of it as analog rotary encoder. There are no switches those are the sensing coil cores, the sensing is completely magnetic. As there is no physical contact with the rotor it is very durable and reliable.
Punched tape was rarely used by Soviet mainframes. At least I've never seen it used although the puncher and the reader were available. And I've seen a dozen of different installations and spent a great deal of the day in the computer hall for several years. Punched tape was used by mini- and microcomputers. ПЛ-150 is a very simple device that has only 1 transistor inside that provides a delayed ready signal to computer. Wiring of the solenoids is directly connected to the input socket. High speed was used for paper tape. Low speed was recommended for plastic tape that is harder to punch. ЕС-1060 was the top model of the stage 1 development, then there was stage 2 with ЕС-1066, and some work on stage 3.
@@ChernobylFamily Apparently it was, but it had buggy VM support. VM/SP did not run on it. So it looked the same old stage 1 from the user's perspective.
@@ChernobylFamily It was some kind of MVS with a home-made dialog system called JEC. JEC had a simple text editor, JCL launcher, and it could spy on the system console.
I got to play with teletypes in the 70's. Punched tapes were usually wound in a figure 8 pattern using the thumb and little finger. I wonder if you've run across any tapes wound like that.
@@seangriffon6502 I believe that you are correct. I'm a Controls guy so I don't really know what the difference is (to me it's bits, bytes, and wires). :)
It always floors me on how the political grip strangled so much engineering potential. There is so much basics to learn from these devices. Everything has become so integrated that it is sometimes really hard to understand how things work on the low level. Here you can touch and feel them. No nano mechanisms here.

"worked straight out of the box", i now know the soviet version of this saying includes several dozen hours of testing, jumped test leads, custom test connectors, disassembly, and repair of previous failure condition. lol
Very true. However, big machines were never meant to be ready out of the box and always required a certain (long) period of installation and testing. Another thing, that in the case of the western tech after that stage started work, not work-repair-work-repair-repair-repair :)
@@ChernobylFamily ha, i know this from owning a cheap car.... but i can always get my car to work. like with the old reliable manual transmission, 384k miles on my 98 honda accord, starter went out and i just push started it for 3 months before finally fixing. stuff isnt made like that anymore. didnt realize you guys were ukranian, guess that makes sense. glory to ukraine&the heros
Thank you! Given 10 mm = 4 bytes, we need 2560 m for 1 Mb. In reality, not that bad, that roll we had was kinda half a kilometre, I think. Still it is MUCH better than if we'd use punch cards.
I am afraid it is a little misunderstanding: we do not have them, we just demonstrate the principle. Most of its code was stored on magnetic tape reels. Nevertheless, at some point here will be a video about SKALA - basically covering what you are interested in.
The switch on the back with the 3 positions looks like a early Hall effect sensors cars use a single sensor with a wheel that is connected to the crank shaft to tell the computer where the engine is in its cycle to fire the ignition
From what I heard in multiple conversations with actual former operators of that hardware, opinions were generally negative, kind in a form of "yes, some machines were serious, but unreliable as a nightmare. Sometimes it was under repair longer than actual uptime".
I'm a precision engineer and we have a couple of very old CNC's that use tapes. We don't use them any more (except for demonstrations). Absolutely love old technology like this

Coincidentally, I also acquired a Chinese made tape punch/read/check device, with concept similar to your one. It has 5/8 bit tape punch, photoelectric tape reader and a keyboard. The unit is electronically controlled, not like other teletypes such as ASR-33. The punch/read/keyboard unit I have weights 17kg but the control unit which I'm missing should weight more than 30kg according to the information I've found!
Just like you, I'm also planning to make a modern interface for my machine. I'm planning to add UART capability(which is a must have) and also USB keyboard emulation, so I can use the machine as a convenient input device on modern computers. I think with your tape punch restored, you can make some customized tapes and seal them in plastic, for sale as bookmarks. They should be very welcomed and should add a little help for funding your bigger projects.
thank you for the story and your ideas! Yes, we are thinking towards such merch. And good luck with your restoration and interface making!
A few (!) years ago, when I was in college, we used the Teletype ASR-33 punch tape terminal to keep our programs between semesters, when they wiped the drives.
Woooow!
Now here's an interesting bit of Venn Diagram overlap between myself and you guys - during the 1990s (the late 1990s, I might add) I had a job with an electronic funds transactor company here in the US called (at the time) STAR Systems, and our main central processing system was comprised of an IBM S390; I would wager the JCL we coded in would run quite handily on some of the machines you've talked about in this very video.
Thank you for a story! Yes, actually a lot of western software would run on ES. In reality, a lot of original IBM-compatible software was stolen/cloned and reworked, surprisingly even often improved with bugfixes ;)
I’m really impressed! I’m sure with an Arduino or a Cheap ESP8266/32 you could get some sort of communication going with the unit, it would be kind of impressive to make one of these wifi or Bluetooth enabled (maybe make it emulate a keyboard of some sort to get data out of the tape and give it some sort of web UI that translates text files back to binary) just to say you did it!
Really excited to see where things go with that control panel too, it looks challenging but would be very rewarding to have a working model going for historical reference.
These PL-150M and FS-1501 outlived their mainframes, as they were used for CNCs, and in some oldschool workshops they are still being used. So there are superrare industrial ISA boards for them, but also there are at least two circuits developed already - one on a simple logic with COM port communication and a DOS program, and more modern one on a microcontroller, also for a COM port. That or another we will try. At least, we'd like to make cool merch - a tape with a custom message :)
@Randy sure!
@@ChernobylFamily If you get ahold of one of those ISA cards - you can most likely use them on modern computers since ISA is still kinda exposed on the tpm header (isa to lpc chip needed tough)
Would be funny to see that old hardware and software working on something modern :D
@@_DSch very much hoping for that. Yeaterday we have visited the Polytechnic Museum in Kyiv, they have both PL150M and FS-1501 and they are VERY much interested to get some adapter as well.
My mother used that kind of machine for CNC programming. Her supervisor made them print "МОЛОДЕЦ НАТАША" on the tape itself at the end.
Haha that is an amazing story! Thanks for sharing!
Good work! Well made and funny video. Just can't wait the next episode...
The next one will feature truly epic hardware.
Made in Czechislovakia ❤, iam too from here, great material thank you
:) thank you!
Vey cool that the speed adjustment makes one gear larger and the other smaller so the relation is changed but the belt size don't need to change. Cool!
Yes, and it is pretty stable working, we have to say!
Hey guys, I think the switches used for synchronisation are called "Hall effect sensors". They are triggered when there are changes to the magnetic field, in this case caused by the little magnet on the inner wheel spinning past.
By the way, this episode was very nicely put together: The little montage while powering the machine up, and the extra information about how punch tape works were great additions.
-Dominic
Hmm maybe you are right, need to take a look again to them closer.
Thank you!:)
I doubt they'd have bothered with full Hall effect. More probably, they'd been reed switches. In Soviet literature, these are often called 'hercon' or 'gercon', 'херкон' or 'геркон'. It's supposed to be short for 'HERmetically enclosed CONtact; spelling it with leading 'h' is the Ukrainian way, and with leading 'g', the Russian way.
In Ukrainian we spell it also gerkon, but you are right, it is not ringing G, it is much softer :)
Mmmm I can't recall that small gerkons, will ask my mate who has full schematics for PL150M.
A Hall effect sensor is a solid state device. This looks like a magnetic coil. I'm not aware of any name for it, beside "pick up coil". It would work on a principle similar to an electric guitar pickup.
@@russellhltn1396 You could be right, as a pickup would certainly be cheaper... But my understanding is that the signal from a pickup is a sine wave, while a Hall Effect sensor is a square wave. If you're actuating a punch with exact digital (serial) timing, wouldn't a square wave be more easily applicable without modification of the signal?
Those 3 "switches" that look like coils on the end of the motor are in fact HAL sensors. They send a pulse to the control board to control the speed of the motor or to "inform" the current speed of the motor for it to punch at precise timing.
Thank you, yes, we figured that out.
Awesome channel that I just found !

Hi Guys, great to see you recovered that mainframe panel. I'm looking forward to seeing it restored. All of the kit, is deeply cool. I remember being reading about punch tape but never got to use it. The box for punch tape has got a nice design. Needs a good clean.
We already made some shopping with the help of patreon, so soon will be some updates on the first cabling work... that is going to be a long journey.
As for the punch... heh, it was green, needed to retrobright it to return the blue color. However a few spots on the top we are unable to clean out with anything...:)
Godd to see that You both are alive and still kicking! If You think i can be of any help, don't hesitate to ask!

@@ChernobylFamily You’re very welcome! ❤️
I was taught the basics of punch tape at Institute of Technology as late as in late nineties, if only to preserve the CNC code on a more modern media (like 3.5" disks or other marvels of cutting edge technology...) Machine shops tend to keep useful hardware around and running as long as possible. And when it's no longer useful, you know it's absolutely *ancient*.
Thank you for the story!
Gotta love the look of old tech! Amazing tech!
Today get ready for a new episode!
@@ChernobylFamily 😁 👍
I worked in the former Czechoslovakia as an EC-1033 and EC-1045 operator😉 We called devices for 2-36mb disks "washing machines" because they visually resembled them😁😁I was still young at the time.
Oh my... Look, we VERY much ask you, if possible: can you write us an email using a 'contact us' on 'about' page of our channel? The thing is, EC1033 was installed at the upper floor of the Duga datacenter, and we crucially will need a consultation of the actual operator of such a machine.
@@ChernobylFamily As an former operator, I probably can't help you with technical matters, the technicians and programmers who took care of the system and repair of boards could do that, although some are still alive, but they are people 70+ and I have no contact with them.
Thank you for your responce! We are particularly interested in work with processor panel and so. Not repairs, with this we have sources.
@@ChernobylFamily Yes, but this operation of the front panel was in charge only of technicians who turned on the whole device and knew what each indicator light meant! They had a manual for it
At least in our case, the operators were not allowed to do anything on this panel, at most turn it off or report that something is wrong. And the diagnostics were carried out by technicians! This means that the error messages diagnosed by the lights were managed only by them. Most of the time, there was a problem with some board and they had to remeasure it and resolder the "cockroaches".So unfortunately it cannot serve😌
@@pumelo1 i see. Anyways, thank you!

Hey, greetings from another lab coat wearing nerd gal with Slavic origins :). Nice unit! I love how it's built, contrary to Allied computers, it's more mechanics than electronics, all so simple and reliable.
Cool that you show synchros, as CuriousMarc just did a video on them :).
...but it required a table-sized rack of circuit boards to function.
Thank you! :)
i think you should show this to curiousmarc and his team if anyone can help you with old computers it would be them
Of course I will do, but with this equipment the only people who really know something are Chornobyl NPP engineers. We had a few meetings with them, so at some point there will be a really massive episode about unique tech.
oooh I cannot wait
@@qmacaulay69 must say, since I commented, we much advanced. But still some time needed
Chernobyl Family, thank you for that video. It brought back many memories for me. I am waiting for your video on that Скала machine. I've read thousands of articles for Chernobyl disaster and I know that Скала was important part from reactor equipment. It will be very interesting for me to see what that piece of machinery was, what was the purpose of all that racks and control boards and lamps and switches. Was it a real computer, how it works. How many programs run on it. What was the operating system. What is program Дрег and how this program takes the measurements of the parameters of RBMK reactor. Please do that video.
Thank you for your motivating words! We will make it as soon as it will be possible. Right now there are severe limitations due to the wartime. However, it is highly possible that we will have a few episodes about its components again before the big one, specifically, about DREG.
I love your humor.
Good luck with your extensive restoration work, which may be laborious!

MWAHHAHA
8:58 Those look like "variable reluctance" pickups. The pointy bit on the rotating bit changes the reluctance of the magnetic circuit for the pickup (coil) as it goes past, and it gives an electrical impulse.
Thank you!
Yeah, the same as the pickups used in electric guitars, and sensors on cars such as camshaft and crankshaft position sensors, and anti-lock brake sensors, I dismantled an ABS sensor last year, and was stunned at how much tiny fine wire they'd crammed in there wrapped tightly around the soft iron core.
I remeber these from Czechoslovak embassy in Baghdad. There it has been used for storage telex data before decryption in another machine. That was back in 1989 so I can confirm it was used probably also in the early 90's. Anyway, thank You for another nice video as always.

Wow! I'm really looking forward for this EC-1060 restoration process. My mom worked on EC computers (she worked as software engineer in soviet union).
We have updates about ES1060 on Patreon and new will come soon. Question: which machine she worked on? We could use a help from 1060 operator...
@@ChernobylFamily I asked her previously, she doesn't remember quite well. She worked on a bunch of soviet machines since 1980th, including EC (but not only). She worked for the Institute of automatization in Chernivtsi branch. Traveled a lot while worked on projects like nature gas pumps automatization in Siberia or automatization of sugar plants in Ukraine.
Continued working there and then in some gov structures at 1990th, but on a more modern computers. And then she switched into accounting at early 2000th.
@@ChernobylFamily I'll try getting more details about EC computers, do you have any particular questions?
@konserv thank you! Specifically we are interested in the work with ES-4001 multiplexer channel control panel. We so far got all internet sources on it and some documentation but without actual operators' testimonials it os hard to proceed.
Edit; 4001 is an integral part of 1060.
@@ChernobylFamily hi, guys. Sorry to say that, but I'm not sure that she can help you too much. She worked mostly with preparing data on magnetic tapes (бюро подготовки данных на магнитной ленте). Within EC machines she mostly communicated with a tape storage blocks, there were other guys who worked with control panels, multiplexers, etc.

When i was at school some of our first programs were punched on paper tape.... i wish i had kept them... paper tape is the ultimate symbol of retrocomputing.

Great video ! Happy to see you both :) Možná byste mohli vědět, nenapadá mě nikdo povolanější, protože to vypadá, že o Duga radaru víte hodně, zkoušel jsem hledat bezvýsledně na internetu, jaké se používaly elektronky v RF části duga radaru ? Nikde jsem tuto informaci nenašel. Looking forward to the next part, punching some code !
Dobrý deň, presne nemôžme povedať - nakoľko zariadenia spracujúce signál sa nezachovali. Logicky - elektrónky by mali byť použité len vo vysielacej časti Dugy, ktorá sa nachádza v Ľubeči 1. Toto miesto nie je prístupné. Existovala celá séria elektrónok, generujucich signál, nazývali sa GU(ГУ) a nejaké čìsla za tým, veľmi silné boli napr. ГУ-23. Možno mali aj niečo silnejšie
My CNC mill measures program execution memory in terms of punch tape length. 321 meters.
That's similar to modern IBM mainframe computers. In its operation system, there are still punched cards readers and writers as virtual entities with some very practical purposes

Love old tech, i call it "mechanical charm" but in the case of that big control panel I'll have to call it "Wiring nightmare"
But my god, you cant imagine how we wanted to find that thing...! That nightmare is nothing comparing to a fulfillment of the dream :)
Thee name of the device is synchro. It was used in old planes and machine to sense position think of it as analog rotary encoder. There are no switches those are the sensing coil cores, the sensing is completely magnetic. As there is no physical contact with the rotor it is very durable and reliable.
Thank you for these details!
very intersting. thank you my friends 😀
Thank you! Check our other episodes, and this weekend gonna come something even more epic!
Punched tape was rarely used by Soviet mainframes. At least I've never seen it used although the puncher and the reader were available. And I've seen a dozen of different installations and spent a great deal of the day in the computer hall for several years. Punched tape was used by mini- and microcomputers. ПЛ-150 is a very simple device that has only 1 transistor inside that provides a delayed ready signal to computer. Wiring of the solenoids is directly connected to the input socket. High speed was used for paper tape. Low speed was recommended for plastic tape that is harder to punch.
ЕС-1060 was the top model of the stage 1 development, then there was stage 2 with ЕС-1066, and some work on stage 3.
Thank you for the details! The only thing, 1060 was stage-2 as it was ibm/370.
@@ChernobylFamily Apparently it was, but it had buggy VM support. VM/SP did not run on it. So it looked the same old stage 1 from the user's perspective.
@@poizaz so what did they use then? BOS ES?
@@ChernobylFamily It was some kind of MVS with a home-made dialog system called JEC. JEC had a simple text editor, JCL launcher, and it could spy on the system console.

"worked straight out of the box", i now know the soviet version of this saying includes several dozen hours of testing, jumped test leads, custom test connectors, disassembly, and repair of previous failure condition. lol
