This Soviet Microprocessor lab looks like a nuclear briefcase!

[@ReverendJasper]

I can imagine that the notes were left inside to assist with the repairs. The repair service was probably shared amongst some of the same workers who did the assembly. The quota for units shipped gets made, and the metrics for repairs looks good as the "damaged in shipping" units get diagnosed incredibly quickly...

[@ChernobylFamily]

Close to truth. And not to disrupt the Good Statistics.

[@MrSzybciutki]

Leaving repair logs in electronics was a standard practice everywhere back in the day, not just in the USSR. I often find them in old equipment. You were supposed to write them all on one piece of paper that you could easily find inside. You had to write the date of repair/maintenance, who did the job, contact info, what was the fault, diagnosis and what repairs you made. Quite often, but not always, you had schematics inside too. Back then a device was supposed to serve you for decades, and it was assumed it would be normal it would go through cyclic repairs, so it made sense. Nowadays most electronics are one time use devices to which you don't even have service access to, which you are supposed to replace in a few years. But it's not like it was limited just to electronics. The practice survived on for instance with cars till this day after all. You surely do keep a log of every repair/maintenance of you car, do you?

[@ChernobylFamily]

There is one difference: it is not a repair log, it is an obscure notice on a glitch. The same we found, e.g. in DVK-3 computer we have a review of here, and by papers that machine was 100% functional, despite it had a dead graphic card.

[@MrSzybciutki]

The wire wrap technology was widely used in the 70‘s up to the 90‘s for computer prototyping, giving you a fast way of connecting pins together w/o the need to etch and manufacture a pcb. Pre-drilled PCBs, IC and other sockets were available with the necessary long pins to wrap the wire around. The wire wrap „pistol“ was driven manually by pressing the handle to rotate the shaft, and some models could even strip and cut the excess wire during the wrapping process, resulting in an enhanced working speed.

[@ChernobylFamily]

Manual...? Interesting, we had electric mostly. We recently got one for our ES1060 restoration project, it is for AC 36V so still i need to get a proper PSU but we gonna use it:)

My take on why they leave these notes explaining what problems the machine have and sold it as having passed all tests is that they had a production goal or received some bonus if there was a low number of faulty units

[@ZiggyTheHamster]

In addition to the other comments around this allowing the factory to meet its defect quota, it also reduces the demand on the factory - some number of customers aren't going to notice the defects (think like dead pixels on LCDs), and with things being so scarce, it would usually be better to ship the slightly broken device than not to ship one at all. The Soviets were, perhaps by necessity or perhaps by conviction, very good about not letting things go to waste. Just don't do this on military-spec units. Also, it would usually be someone else's fault it's broken ("damaged in shipping" but leaders would consider that to be more tolerable than marginal silicon), happily repaired, and everybody looks great on paper.

[@ChernobylFamily]

Yeah, it all was about the fulfilling the plan. The most important, things have to be good on paper.

This reminds me of a microprocessor trainer I learned on in school. I shouldn't say "learned" on, because I never understood what I was entering or seeing as output. You just typed in everything in hexadecimal, and then saw whatever output on a small little LED display, just like this unit. I hated it. Everyone in my class that used this basically just entered in the programs as presented in the book, verified the output was what the book said it should be, and checked off the lessons until we could move on to the real prize - our Heatkit H8, where we would all learn BASIC and write little games for ourselves. Well, at least in between constant bouts of component-level troubleshooting and desoldering/soldering RAM chips in the thing. Fun times.

I was looking for a completely different chip on eBay and happened to check what other items they had for sale, and it turned out they had a lot of interesting chips for sale, so I went on a bit of a shopping spree! Anyway, that was a very interesting video on a very interesting computer. In western countries you could definitely buy computer kits that were a lot like this during the mid-late 70s.

It was somewhat similar to Altair in its minimal configuration, but in maximal it could have a display and a keyboard.

Someone should program this thing to run a Minecraft server.

We do not know even a little about minecraft, so hard for us to get wheyher it is a joke or not:))

I think that Soviet technology was (and now Russian, Ucrainian, Latvian, etc. is still) so underrated also in EU. Probably due to US propaganda and aggressive commercial policies of US software corporations. Your channel is so interesting for me! I'm an Italian developer / sysadmin and I think that history of IT is import and it should be know... many novel engineers (at least from Italian universities) know only 3 things: Java, Agile, Project management... they dunno how a computer works, nothing about ancient computers, microprocessors, etc. all over the world and who developed them 🤔🤐

[@ChernobylFamily]

There is nothing underrated. Generally, it is all stolen and reworked western stuff. There were amazing ideas and talented engineers who were generally suppressed by communist regime. Please, I do not want to hear a word about 'U.S. propaganda' here, as it has a very strong russіаn flavor, which we in Ukraine do not withstand by obvious reasons which on daily basis fall to us from the sky. Thank you. Nothing personall, judt if you'be in our shoes, you would get very quickly, where real propaganda is.

[@ChernobylFamily]

By the way, after some thinking: you are partly right; but in an opposite way. During Soviet time, everything was arranged that way, that outside the USSR all would be perceived ar russian achievements. Even today, in the west some people by inertia call all us russian, which is actually really offending. And that is the thing, many good people were obscured by this, and still are.

[@alexandervt641]

It is interesting and important to study the Soviet computer history. In the West there is very little known about that. There were a lot of gifted people with great ideas. In the end, they helped to save the nuclear balance. Ukraine was one of the centers of Soviet IT development. However, I agree with the authors: Because of the totally inefficient Soviet economic system Soviet computer technology was lagging far behind the West.

Yes...) in fact, initially I wanted to output a word "BEER" as I have been recording that on Friday :)

[@johnvlahidis_google]

In a production line, such as the production of tractor parts, it was quite dangerous to point out, a continuous defect, in the production machine, (that reduced the quality) to your supervisor because they could accuse you of doing it, to your detriment. Even more so if you did it on a device like this, sure you are in a moment a Bраг народа direct to siberia

[@ChernobylFamily]

Not in the late 80-s, though. Here we deal just with a systematic ignorance...

[@JanicekTrnecka]

Those LEDs - horrible power consumption and barely emitting light, I suspected them for having an incandescent filament inside :D since some of them produced a lot of heat too.

[@ChernobylFamily]

...but, the color is beautiful, at least ;)

[@JanicekTrnecka]

​@@ChernobylFamilyvery nostalgic vibes, they look very similar as Czechoslovakian TESLA LQ100 series leds, with partially metallic package.

[@ChernobylFamily]

I won't be surprised if those are them.

[@JanicekTrnecka]

@@ChernobylFamily this is more than probbable in "RVHP" environment.

[@ChernobylFamily]

I mean, that textolite pcb material is what you'd find inside Tesla products. That said, it would be logical to have there locally produced LEDs as well

[@Pythagoras1plus]

label and buttons are cyrillic, but the led are labelled latin. why?

[@ChernobylFamily]

Because in KR580VM80A (and in all chips produced by the USSR) signals/states were marked in the same way as in what they cloned - in Latin/English. In this particular case, it is like in the original i8080A. There is a worldwide way to mark such things, they followed it, it was easier. Besides other reasons, it allowed to use western documentation and literature easier.

[@Pythagoras1plus]

i just realize hexadecimal numbers are latin too. i live in bulgaria for half a year now and it puzzles me every day how cyrillic is often mixed with latin. i'm not used to cyrillic that much yet but it seems, because of the ambiguity of some letters, one has to reread a word everytime you encount a certain character. i suppose that's normal in countries with cyrillic script or how do you experience this?

[@ChernobylFamily]

Frankly, we do not have any problems with this as we are in the environment of two alphabets from the time we are born.The perception is somewhat automatic. I remember when mobile phones did not support Cyrillic, we used to write with Latin in a transliteration, and people read that fluently:)

[@Nazardi0]

Ну ты показал детям в школе ардуино, смог объяснить как работает процессор?

[@ChernobylFamily]

About Arduino that was a joke, actually.

[@newrecs4969]

call it the TSARDUINO lol

[@ChernobylFamily]

No, thank you
