content: Mush of the developments that pushed electronics forward were the product of work at places like Siemens and the British Radar work and then the integrated circuit as we now know it at TI and Fairchild to name a few. That is, much of this work was done in the west. As IC's evolved into micro processors and RAM the capabilities expanded exponentially -- but again, much of this work was done in the west at places like Intel and Motorola. So, over this time there was very little known about what was going on in the former Soviet Union on a lot of things but here I'm concerned about how they went about producing or acquiring electronic components. As someone that's been in the semiconductor industry since the early 80's and has seen the evolution and revolution from within and also aware of the incredible cost to build a FAB and produce the tooling needed I even more puzzled by the black hole that was the Soviet Union's electronic industry. Please, I'm not interested in starting a flame war and I no desire to ridicule what they did so I would hope anyone wishing to comment would keep that in mind and offer any insights you may have in a factual way.In it's current form the semiconductor industry, at the 10nm scale, is insanely expensive as the core tool needed to do this, lithography, is now at the $80M USD per machine price level and there are very few players in the litho business with the skills needed being very cutting edge. And, decades ago, even though the demands for litho were no where near what they are today there was still the problem that only a handful of companies in the west were producing the processing tools so either the Soviets were able to construct there own industry with the own processing equipment or they had to get there hands on tooling from the west.Part of my problem, I suspect, is that my knowledge of what the Soviets did is limited by the fact that they were pretty closed mouthed and we in the west largely went on viewing things from out perspective. It seem likely that the Soviets must have done some pioneering work but we in the west knew little about it.So, beginning at the component level of transistor and IC production then moving up from there to PCB's of various function, how did the Soviets stay relevant with the west. Soviet missile technology has been on par with the west since the 50's and by some measures are and were at least equal and perhaps ahead of the west. Making such things work requires real competence with electronics and more to the point, the ability to produce them. In the last few decades the microprocessor has revolutionized everything and perhaps no where more than military hardware such as fighter planes. The narrative we have in the west is the it was Intel that, with the 4004, ushered in the microprocessor but, once again, the story of the Soviet developments in this field are once again unknown to me.Hopefully some of our Eastern European members can fill in the blanks here and of all the former Soviet republics perhaps our Czech, Hungarian, Ukrainian and Polish members can address this.Again, I want to be clear that my interest here is an honest one and I do not want this to devolve into an East versus West debate. Yes, espionage will have played a roll, it always does, but there were and are many brilliant people that few of us in the west ever heard of.Brian

content: Cost is no problem when you run the whole country as one big company.The question is too generic. Up to the 80s Soviet Union was on par with the world. It was lagging a bit, because a lot of new development was "inspired" by what was happening in the west. But ability to throw a lot of money at the problem ensured fast catching up to any new developments.Soviet Union had its own machines (including stuff made in GDR), but IC designs were borrowed in a lot of cases. In some cases they were just mask copies, in others just functional analogs redesigned from scratch. A good representation of a complex IC available at the peak -https://en.wikipedia.org/wiki/KR580VM80A. After that the development of own technology essentially stopped.

content: Well, I am hardly an expert but the Eastern bloc was quite successful at both cloning and developing a lot of semiconductors. I don't know many Soviet parts but e.g. the Czechoslovak TESLA was producing the 7400 logic series (MH74xx/54xx/84xx), the 4000 CMOS series, lots of analog ICs too - e.g. uA741 was produced as MAA741, LM723 as MAA723, etc. I still have quite a few of these in my junk bin.E.g. Intel 8080 was produced as MHB8080 by TESLA, I believe they were producing also an 8088 or 8086 clone. East Germans were making Z80 clone U880 which has found its way into many home computers.You can have a look at what ICs TESLA was producing e.g. here (under Catalogue):http://www.tesla-ic.com/The same for vacuum tubes, transistors, diodes, etc. Soviets were manufacturing these things on a pretty large scale too. There are plenty of websites showing these things, e.g.:http://www.cpushack.com/soviet-cpus.htmlThen there was a pretty large scale computer industry - both clones (e.g. the IBM's System 360 and DEC's PDP series) but also completely own designs. The same for test instruments, radio gear, etc.Pretty much most of the electronic industry production was going either into military applications or further industrial deployment. Consumer electronics was pretty much the last to get any of this - e.g. it was common to have a black & white vacuum tube TV until the mid-late 80's where I lived. Solid state and color TVs were rare, expensive and mostly crap.There has been also quite a bit of own R&D done because importing Western components was either very difficult (limited hard currency reserves) or straight impossible (embargoes). Espionage certainly played a role but probably smaller than you think - the Eastern bloc did lack modern resources compared to the Western counterparts at the time but certainly didn't lack first class engineers and scientists.And to fly an ICBM on target you don't need a supercomputer - especially if the thing carries a nuke that will flatten a city of several millions of people. Then you really don't really care if it has an "accuracy" of several kilometers ...Also both as a consequence of this lack of resources and access to the modern components the designs were quite a bit different - more primitive and crude, with engineering ingenuity having to make up for the lack of resources. However, the gear was often built to withstand much worse handling and conditions than Western gear ever could. Just compare e.g. the Vostok or Soyuz space capsules with Apollo - much much simpler and primitive but thanks to that there was much less that could break and cause problems (not in the least due to the infamously sloppy workmanship).

content: Quote from: Cerebus on March 03, 2018, 03:13:09 amWhen I mentioned Russian missiles I wasn't so much talking about nukes as SAM's and air-to-air missiles -- these don't work very well if you can only expect to get within a km or so. The advances in Russian SAM's were game changers for the U2 missions and some say it even made the XB-70 irrelevant as well. So, even back in the 50's the Russians were making some pretty good missiles -- some of which are still in service and lethal.I suspected some of the IC's and components were thanks to espionage but it's also the case that Russia had and still has lots of brilliant people -- we just don't get to hear much about them in the west. If what ataradov says about the development work ending in the 80's is true, and I find it hard to imagine that Russia would have ended all development and production work on components that were critical to there weapons programs, it would suggest that with the fall of the Soviet Union the Russians have had more-or-less unfettered access to western IC's and components and that more recent systems would then be based on western IC's and components -- again, that seems a bit suspect given the strategic aspects of there weapons programs.And thanks to janoc for his feedback on the work done in the Czech Republic during the Soviet era -- outside of Russia itself the Czech Republic and the GDR would seem to have been the other centers for Soviet technology.The 1980's were a milestone period not only for the demise of the Soviet Union but also the move to VSLI and the need for much tighter cleanliness requirements as feature sizes reached below a micron. In the early 80's, when I worked at IBM East Fishkill, we were transitioning our thermal production tools to cantilever system to eliminate the quartz-to-quartz scrapping that was the norm up till then. As you can imagine, pushing a quartz boat/sled into the quartz tube of a furnace was very dirty and up to the early 80's, because feature sizes were between 1um and 10um, the contamination was livable, but when feature sizes got smaller that no longer was acceptable. So, I can see that copying or catching up was more feasible up to the early 80's and less feasible after that point.Thanks also to blueskull for his comments vis a vis China -- though not strictly what I was asking about the needs and methods would appear to have been similar. One thing I'd argue with is his comment about western education systems focusing on "useless" things like creativity and freedom -- our universities are filled with Chinese students so one would think they see some value in the approach. You can copy if you are good at engineering, but to innovate requires something more and in this area the west still leads the world -- though the lead is shrinking...Brian

content: Quote from: raptor1956 on March 03, 2018, 03:53:25 amIt did not end abruptly, it just slowed down to the point of near death. There are still factories from that time that still make ICs (they have switched to modern equipment, of course), so the industry did not die entirely, it just really stopped developing, new equipment stopped being produced, all the associated research institutes shrunk in size.While military is a big part of demand, consumer electronics contributed a lot as well. And consumers started switching to imported ICs, since they were easier to get, there were no supply shortages.Quote from: raptor1956 on March 03, 2018, 03:53:25 amMilitary people did not really adopt digital ICs as much, a lot of those ICBMs are still analog. Digital ICs were mostly used in non-critical ground equipment, like computers for R&D and stuff like that.And it still happens to this day. If as a developer you want to use an imported component (if there is no equivalent Russian), you just write a note-type document (1 page) with clarifications of your requirements. If it gets approved (in many cases it does), supply people will buy some stock for maintenance, and you are free to use that component. And then as a result, in theory an R&D (called OKR in Russia) projects starts, and some of them even end up with a replacement component.This rule is easier to apply to high-end stuff. Russia goes not make really big FPGAs, and some equipment is impossible or impractical to design without them.Again, typically stuff that actually goes into actual rocket is all done with Russian components and components from Belarus, since it had huge concentration of manufacturing in Soviet Union, and Russia has good relationship with them.But bear in mind, Russia considers ICs designed in Russia, but built by TSMC to be Russian for the purpose of this discussion.

content: Quote from: raptor1956 on March 03, 2018, 03:53:25 amThe electronics for such systems can be deceptively simple. The only controlled technology needed beyond the rocket/propellant and explosives are the fast IR detectors such as HgCdTe or PbSe which can be made in low volumes without the vast complexity of a semiconductor lithographic process.Back on more generic semiconductor technology if you rely on wikipedia you get a very US centric view of the world, but you can find a little on the periphery:https://en.wikipedia.org/wiki/Angstrem_(company)https://en.wikipedia.org/wiki/Mikron_GroupAnd thats before you delve into all the allied countries during the Union of Soviet Socialist Republics.

content: I remember my first job at the CMOS factory, in Far East of Russia in 1992 as a quality engineer. We made some IC for military - K765 series, along with common "citizens" series K561 & K176. Know that 765 was for some anti-missiles, alike "Patriots".I wander, that discussions doesn't include Japanese electronics, myself and all my friends dream about Japanese consumer electronics at that time, not american.Regarding miniaturization, nano-technology - nm processes, it's not for battle field, nm and radiation/EMI resistivity is in inverse proportion. Can't see how the dumb size reduction may lead the technology. Rather the way to colonize the world.

content: Not having the brains to be innovative, Russian scum copied most IC's that US companies invented - even Intel ICs. Now its China who demonstrates it does not have the IQ to create anything much, just copy and steal, without a conscience. The USA should always be honoured for its great technological leadership in electronics. No-one can deny America's contribution to electronics and technological innovation - past, present and future.

content: An acquaintance who grew up in Russia told me that in the late 70s various research labs there had produced competent CPUs that had good performance. However, the government instead decided to fund the cloning of chips used in the DEC VAX series, because those were the computers that ran the CAD programs used to design aircraft and missiles. Industrial espionage took care of getting the CAD files into Russia, where they could be studied and improved upon. Of course, this is probably third-hand information since I have no reason to believe this guy would have worked on this stuff himself.

content: There were clones and entirely new CPUs developed and produced at the same time. I have never heard of stealing the software though. All CAD-like software I've seen was developed in the Soviet Union. Or at least it was masqueraded well enough - all translated into Russian, using metric system, and adhering to GOST standards.The software was pretty primitive, so I don't know how much of it was actually used for designs.The mathematical software was pretty advanced, but that was just command line stuff written in Fortran.

In at least one area they are clearly the world leader -- consumer drones, no one is even close to them as GoPro discovered. When you have millions of talented engineers performing tasks like building production facilities for Apple etc, sooner or later some of those engineers will strike out on there own in much the same way engineers in Silicon Valley have done for decades.Please, although we've had one person go off on a thinly veiled racist rant I'd hope that we can stay on point here and avoid such nonsense. As someone that's been in the industry a long time I'm interested to know about what went on on the other side.Brian

content: Quote from: Someone on March 03, 2018, 04:35:33 amThe missile system that took down the high flying U2 flown by Francis Gary Powers in 1960 was not an IR missile but instead was radar guided with ground based command. In addition, anything traveling at Mach3 had better have pretty fast responding controls or it will miss the target by, well, miles. If it were so trivial why have so few nations, with large budgets at there disposal, been able to cob together something comparable 60 years later? Even advanced missiles from places like the USA are not 100% effective against fast high flying targets -- IE the Patriot Missile. Additionally, during the 60's and the Viet Nam war the principle longer range air-to-air missile in the US arsenal, the Sparrow, was pretty damn useless in spite of the advanced electronics we had. Intercepting and destroying a fast moving target at high altitude is non-trivial!Brian

The fact that rocket hit is a miracle, it was at its absolute limits, and he happened to fly right over the launch site. And the reason he had to fly over that place is to take picture of some unusual activity, which actually was testing of those new rockets for S-75 launcher.

But the usual game of cat and mouse continued on as counter measures and then counter counter measures were deployed for radar based systems and IR navigation. The point was that missiles didn't need advanced electronics to do their amazing tricks, just a lot of money spent developing and testing them which both sides seemed to have available.

content: I've heard a lot of stories from my older colleagues as I'm too young myself to have been working in soviet times.As there was shortage of pretty much everything and the military was priority, the best stuff was allocated for military use only. For example, transistors with KT prefix were commercial-use and 2T were military-only. The military-purposed ones were better (tighter tolerances), but they were not allowed to be used in commercial applications. Hobbyists were able to get some unofficially sometimes, but they definitely could not be used in manufacturing.For commercial stuff (ie radios), the components were split in 3 categories: things you could use, things you had to get special permission to use (incl paperwork showing why any substitution is not possible) and the stuff you could never use. It was not building down to a price point like now - you were not allowed to use these components at all. The allowed components had very large tolerances, so the schematics had to be engineered to cope with both extremes. For example, the probably most common transistor, KT315/KT361, had h21e of 20-90 or 50-350 depending on variant. And taking apart whatever device manufactured after 1980-ish, there are very probably some KT315/KT361 inside. Your schematic solution had to handle the variance, whatever was thrown in ther during the manufacturing.All of the companies were state-owned and governed during the soviet times (with some small exeptions at the very end). Some engineers, who worked in large and important engineering bureaus at the second half of eighties, told that these larger and most important bureaus were actually using western gear - tek, rohde etc, because these were much better. These were smuggled into the country, probably at the goverment level. Officially, this gear did not exist. Even if development was done on these, the type qualification and all official testing had to be done with soviet equivelents. Engineers of that times have told me, that they were going mad with passing the testing - the better western gear told that everything was passing, but the official tests with soviet gear failed... And they had to tweak the products to get the required results.Copying western stuff was not only ok, but required. Old engineers have talked how some officials smuggled some western audio gear into the country and then brought to the engineering bureaus to reproduce. The only issue was that the western component base was so much better that they had to design the internals ground-up. Of course these clones were much lower spec, but still looked quite similar. For example, there are tales that the gov officials in moscow had smuggled some Sharp Optonica audio gear to moscow. The management of RET engineering bureau (Tallinn, Estonia) were called in to Moscow and asked why they do not make stuff like that. They were given orders to reproduce the gear. The gear sold as "Estonia 010" series were visually and functionally clones of Sharp Optonica SM5100, RP7100 etc. The Sharp amplifier used ic output stage, it had preamp and power amp in one box. Soviet engineers did not have ic amplifiers, they redesigned the device with discrete components. Their version was much larger in 2 separate boxes (separate preamp and power amp), both of the boxes were 5cm wider. But the overall design and functionality was quite well copied. The record player was unique because it had automatic track searching etc. The sound quality was quite good considering soviet stuff, but the reliability was just horrible. Designing that large functionality with high count of unreliable discrete components meant that the failure rate was very high - i've seen probably more dead Estonia 010 amps than working ones.Digital and microprocessor design was also very different. Most of the 74 series etc had soviet equivalants (K155, K561 series etc). The microprocessors were either mask copies of western stuff or functionally equal redesigns. Some older colleagues tell that when microprocessors became available outside of military market, the first years they were only able to get their hands on broken ones - the boxes of processor trays came with errata sheets, that listed which instructions worked on that batch. You had to program the code on that batch of controllers with those instructions only. A year later, these sheets changed to listing the instructions that did not work.

content: Quote from: VK3DRB on March 03, 2018, 05:18:05 amEven most Americans with a little knowledge of history will tell you America was a technologically somewhat backward country at the end of the second world war. The reason they did so well in that war was their size gave them enormous production capacity. They didn't do well through their technological edge. After the second world war the cold war made America open to importing talent from any place it could find it, and build a technological edge in as many fields as they could. This worked rather well. Walk through an engineering department in the US, and you'll find a lot of the smartest and most respected members of the team come from those countries you think lack talent.Someone coming to the table late is going to be at a disadvantage, endlessly trying to catch up with those who arrived first. China knew that, and has done a lot to absorb technology and catch up over the last 40 years. Now many of its major technology companies are on par with western ones, they are increasingly funding original research. Expect to see interesting things from them in the coming decades.

Same for their thyratrons, plentiful, cheap, and very good at high energy.I used to maintain some products made in Lithuania.. My gripe was that GOST series mil spec connectors were poorly toleranced crap and difficult to assemble compared to Amp/Cannon...One major difference. Soviet era high power equipment had tougher safety regs, you pop the lid and any large storage caps are immediately discharged.One thing USSR seemed to excel at, large SCRs and high power, high voltage, NPN transistors. The Lithuanian lasers I worked on had NPN inverter transistors for which there was no western equivalent.The Rs and Cs used were quite nice, if a bit bulky. What is the deal with that weird shade of green paint used for many discrete components and transformers? Was it for tropical conditions or something?Steve

content: Quote from: blueskull on March 03, 2018, 04:21:33 amCareful there. I was teaching at a fairly large Danish technical university and I had regularly Chinese students in class. They were excellent in things like doing crazy calculations from memory - one guy had it literally calculated faster than I could punch it into a calculator ... My Danish students were absolutely no contest for them in this, especially given that many didn't know how to work with fractions, negative numbers, etc. (not kidding!).On the other hand, these Chinese students were almost always utterly lost unless toldexactlywhat and how to do. When it came to actual problem solving where they had to think for themselves and actually decide on their own approach to it, they were hopeless and the Danes were running circles around them. It was a completely foreign concept to them - they were used to a system where teacher tells them exactly what to do and they do exactly that, not a step aside. In Denmark (and the rest of the Scandinavian countries) the kids are taught independent thinking and problem solving from a young age, constantly working on projects and similar. So this is second nature to them. The creativity part is a natural component of this, including studying subjects in humanities to give them wider cultural background.It shows that different education styles produce different results. I am pretty sure the Danes would have learned the math better if they were pushed (sadly the trend has been to go exactly in the opposite direction - but that's another debate) and most of my Chinese students did actually figure out that independent thought and problem solving part after a while, especially because we were forcing them to work in mixed groups with the Danish students so they were learning from each other.However, saying that the Chinese students have a "solid engineering background" is a bit of a stretch, IMO. I am sure they have excellent background in math, physics and similar things but that isn't everything. Engineering is first and foremost about problem solving abilities.Now, just to be clear, I am not saying that the Western students are better or worse than the Chinese kids. They aredifferentthanks to the different education systems they come from and each have their own pros and cons.

content: Quote from: coppice on March 03, 2018, 11:41:34 pmSorry but that is a rather oddball argument. Of course, the best of the best will prevaildespitewhatever screwball school system they were exposed to. However, what about the rest? Or those shouldn't have a chance at education because they aren't "good enough" and didn't manage to overcome the handicaps imposed on them by the school system? And that were not really their fault? (I have heard such views as well). Social arguments aside, even from a purely pragmatic point of view that would be a disastrous approach - we are sorely lacking engineers already - and 90% of those positions don't really need those best of the best, the "middling" ones would be fine.I am not sure why do you think that what I have said was unfair. I have been speaking only about my own experience with my own students, not generalizing it to all Asian kids. However, I can tell you that even colleagues from places like Oxford had the same issues.And finally - you are speaking about spoon feeding. That's not all what I have meant. For me spoon feeding is giving the student everything prepared on a silver plate so that they don't have to do anything themselves. I am not sure whether you have had any experience with Chinese students but I can tell you mine were certainly not "spoon fed" in the schools they were coming from.What they had behind them were years of a hard drill - how do you think they got those math skills, for example? However, the problem with drill is that you don't get to learn how to actually solve any problems apart from those you were drilled on - and then have no idea what to do when faced with something new. What I meant is that these students were used to the teacher telling them - "draw this, calculate that". The decisions were made for them by someone of a "higher rank" and it wasn't up to them to question them, not that they were "spoon fed". There is a large cultural difference there - in Asia the teacher is a figure of authority and what they say is sacred.One consequence of this is also that an Asian student will almost never tell you they didn't understand something - they will always say that yes, they understood everything, even though they have no clue whatsoever. It took me a while to figure this one out. The reason for it is that the teacher is a senior figure in their culture and saying that they didn't understand something would mean the teacher didn't do a good enough job - which would be disrespectful. So they will never say that. And you are left scratching your head about what is going on.

Get a sense of proportion.Quote from: janoc on March 04, 2018, 12:40:35 amI have spent the last 25 years living and working in East Asia with the engineers that come out of their education systems. What you describe is exactly what they term spoon feeding, and what many of them are unhappy about with their education. Hard drilling on narrowly focussed problems, not always gaining much depth of understanding, or development of their ability to break a high level problem down into pieces and solve those pieces. A whole lot of drilling on page after page of fairly similar questions, until they can just spot the patterns in the exams and rapidly churn out the answers. Anything that doesn't fit the patterns makes them step back, because they haven't had their ability to deal with arbitrary problems nurtured in their classes. The brightest are just thrown for a moment. The less able can get badly stuck.Quote from: janoc on March 04, 2018, 12:40:35 amYeah, I can relate to that. The healthy respect for education and educators in Asia is certainly a good thing, though. Its a pity there isn't more of that in the west. The downside is their referring to degree certificates as sandpaper. I doubt that term needs explanation.

content: A bit off topic, but Soviet military products kept up with western products (or were superior) at least partly due to different approaches. One obvious and widely reported example was ICBMs. Soviets had superior rocket engines, thus more throw weight, and less need to miniaturize. Another fairly widely report difference was Soviet superiority in many types of math. Rather than needing a super computer to simulate or numerically solve a system a direct solution was developed. When microprocessors took off the advantage for that approach was too great. There are many examples of this sort of thing.While some claim some inherent superiority in one system or another, often it is more a matter of chance. The winner is the one that picked the right horse initially. When IC's started out their widespread impact wasn't widely understood, if at all. By the time the difference was obvious (a decade or two later) it was impossible to catch up on the investment in all of the varied infrastructure.

content: Quote from: coppice on March 03, 2018, 11:45:29 amWell, the US was not the backwater prior to WWII that some make it out to be and the role the US played as the arsenal of democracy, as it was called, can hardly be ignored. To be sure it was behind Britain and Germany but not by that much. The powered airplane and automotive assembly line were pioneered in the USA long before WWII.I agree, however, that for many things the east, that is China, has largely caught up at the consumer level but much of that is down to the fact that they now produce most of the worlds consumer goods. Apple may design the iPhone etc in the USA, but most of it is made, or more accurately assembled, in China. The other eastern nations were on par with the west sooner -- think South Korea, Taiwan and of course, Japan. At the cutting edge, however, the west still leads the east though even there the gap is closing.Sadly, with all the talent at there disposal, Russia has lagged behind with the singular exception of military hardware where they are pretty near on par with the west. One has to wonder what Putin thinks about there situation vis-a-vis China -- at the beginning of 1990 China wasn't even in the top 10 of world economies and within two decades they became number 2. Russia has focused so much on the west they hardly noticed as the southern neighbor eclipsed them economically and, by reasonable projections, militarily within a decade or so. Of course, if the current trend continues China will become the dominant economy, supplanting the USA, by about 2040 and perhaps sooner.Brian

That is why we can buy Roundup cheaply rather than paying Monsanto a fortune. But until the expiry, Monsanto deserved every penny a a reward for their R & D and innovation, producing a great product.

It will be this way for many years to come.Who invented TV? Before the Scots lay claim to it they should check out the work of Vladimir Zworykin. In any case, it was the American innovation that made it a commercial reality that we all benefit from today.

To take out a hardened missile silo (which is the goal of a first strike or a first retaliatory strike) you have to strike within 50 yards of the silo. Taking the accuracy probably into account, you have to use multiple warheads or your warhead has to have much smaller Circular Error of Probability to ensure that every silo is destroyed and can't fire back. The Russian's missiles never had that kind of accuracy, our's did. That fact is what lead the Russians to negotiate the SALT treaties on the ballistic missiles. They probably didn't know it at the time but we already had highly accurate cruise missiles in development and starting to go into production so loss of the ballistic missiles such as the Pershing II was not significant to American offense or defense.Destroying cities was never the goal of the American nuclear forces, their first goal was to destroy an enemy's capacity to launch nuclear missiles and/or nuclear bombers that could threaten America. If necessary, enemy cities could have then been destroyedat leisureonce an enemy's offensive capability was destroyed.

Truman’s changing language about Hiroshima"which is an excellent piece of original historical research, working from primary documents such as Truman's draft speeches, about what was known beforehand about the targets and the mix of military and civilians at Hiroshima. (TLDR; it was clear that Truman knew they would cause mass civilian fatalities and casualties and was preparing to spin it in a fashion not dissimilar to the spin put on the Iraq invasion by both British and American politicians - nothing changes.)

content: The size of economy in my view matters a great deal since that defines your natural market as well as your "safe" market. The size of available resource is obviously dependent on the size of the economy. Less visible perhaps is with production or manufacturing and for when one has to import/export to survive, the risk of development just increased significantly. Risk of course is a big impediment to development, so size matters.Given the strength of the Soviet military, one often forget how a small GDP they had. Soviet era numbers are hard to come by now, but looking at projected number for this year (2018):GDP (trillion dollars/1,000,000 million dollars)1 @ 20.2 USA2 @ 13.1 China3 @ 5.1 Japan4 @ 3.9 Germany5 @ 2.8 France... UK, India, Brazil, Italy, Canada11@ 1.60 Korea (presumably South Korea only)12@ 1.52 Russia13@ 1.48 Australia14@ 1.42 SpainIn GDP terms, Russia is not even the size of South Korea. It is less than 10% of the USA and just over 10% of China.The other telling stat PPP:1 @ 25.1 China2 @ 20.2 USA3 @ 10.3 India4 @ 5.55 Japan5 @ 4.31 Germany,6 @ 4.14 RussiaGiven Russia's limited size in terms of GDP/PPP, they just don't have the scale of what the larger economies can support. Technology development in almost all known era and country came from first use and learn from others, then copy/imitate, then create their own almost as good, then, perhaps exceed that of the original tech leader. But to "create your own" you need a market for it and their market simply is not that big.In my view, given their small size economy, Russia is doing exceedingly well.However, I think Russia needs to buy from itself more - that will keep more of the dollars in-country for further development. What to me is clear is: Russia is too small to compete with China or USA on it's own, it needs partners.EU seems to be suffering from self-inflicted wounds in their economy. They just absorbed millions of adults to educate. While it is too new to be reflected in current number yet, but absorbing millions of uneducated adults has to take a toll. This is not an era of human muscle powered economy so cheap labor is not going to help technology much. Until those new arrivals risen to par, EU is in "holding up" or "catch-up back to what it was" mode. Besides, there is the risk of needing another generation or more for that to happen.If one takes EU (as partners to Russia) out of the picture, there is Japan, India, and Korea in their near-by geography. That will put them near as "viable competitor" to the big-two but still not as big. Lacking a bigger safe-market or a bigger resource pool, Russian technology development (in manufacturing or creating new technology) will have a hard time keeping up with the big-two. The future will be an interesting one.Edit - opps, forgot to include the link to the GDP/PPP source I used:http://statisticstimes.com/economy/countries-by-projected-gdp.php

content: Quick comment about US A-bomb and Japan. Given the fact that Japan had distributed a lot of the manufacturing into the neighborhoods where people lived, many homes having a drill press or lathe etc, it would be fair to say that everything was a legitimate target -- by the norms of war. But, by the time the bomb was ready most of the major targets had already been obliterated using conventional and incendiary bombs so the idea was to test the a-bomb on targets that were still largely intact. Again, by that time there wasn't much that was still intact. The targets pretty much picked themselves given the above.As to the Russian electronics thing ... perhaps the biggest problem Russia had was that because they were so successful at espionage and saved a lot by not having to develop things themselves they didn't invest as much in research as a consequence. They did whatever they needed for military work but there wasn't much money left for consumer electronics. So, there great success at spying actually hurt them in the end. But, just to be clear, Russia has and always has had brilliant scientists and engineers and they did more with less than pretty much anyone on the planet. The current political order isn't helping them move forward, sadly!Brian

The issue more-so is the electronics industry in the U.S.S.R. was classified. I'm not sure of their system of classification, however I want to say they were secret with their industry in general. Many organizational systems were considered military versus civilian for approval of funding reasons I am thinking though forget exactly.I've read before the U.S.S.R. electronics devices used thicker and more gold in particular though were scrapped for the material post the collapse throughout the U.S.S.R. member Republics.Germanium, Tantalum and Niobium electronic components were developed more in the U.S.S.R. I read somewhere where the U.S. did also... though Tantalum was more there as well as the other materials. Titanium was also, though more needed by the U.S. for aircraft production, e.g. the A-12 & Sr-71.

They did a rivet-for-rivet clone ("TU-4") in two years which was almost more remarkable than the original US development.Of course they were working under threat of death or being shipped off to a Siberian gulag. Lavrentiy Beria was the head of the secret police and overseer of the TU4 project and enforced "copy exactly" even down to the repair patches on the outer skin. And with all the original problems like engine overheating. They successfully copied the air-frame and engines, but were forced to buy the landing gear and especially the tires on the war-surplus market in the US The Aviation Day parade in August 1947 shocked the American observers that the USSR had successfully cloned the B29

content: I recall reading an article about this cloning in either Popular Science or Popular Mechanics in the late 1950s or early 1960s. One of the interesting comments was that dimensions and shapes were easy to duplicate, but the alloys and heat treatments were much bigger challenges. These were often detected by some sort of in flight problem. And was one of the reasons the TU-4 didn't get produced in large quantities.

content: Back in track with the original thread; Soviet made electronic components.I am no expert on Soviet microelectronics. But............What is apparent is that they kept using glass-state devices for a longer period of time. For that reason, several products achieved significant development, and continued to be mass produced long after the west decided to abandon them.A fact that, for vintage component collectors like myself, is pure joy.Thanks to this, there is still a decent supply of Soviet made tubes, Nixies, Dekatrons, Geiger tubes and other oddball devices.

It is pulled out of the silo, the warhead is removed and replaced with a data package, and it is trucked out to Vandenberg AFB in California, along with that missile's crew. Then, they do the whole live fire test. NORAD sends them a emergency action message, they decode it, open envelopes, enter codes that decrypt the launch software and load it to the missile, and then turn their keys to launch the missile at Kwajalein. There, they have radars and hydrophones that locate the splash to <way above top secret> accuracy.I have no idea if the Russians do this level of continued performance testing.Jon

content: Quote from: raptor1956 on March 02, 2018, 11:38:38 pmIs that really true? I worked with a guy who was recruited from a high-level military intelligence position (so the company we were working for could help win military contracts). He was always adamant that the biggest failure of the intelligence community from the 50's through the 80's was their total failure to realize how far behind the USSR was. He had many reasons why that failure happened that are outside the scope of the question asked, but there was most certainly a perception that permeated western society that the Russians were *really* dangerous, when their technology was in-fact far, far behind where were assumed. It wasn't due to lack of engineering brilliance. If anything, engineering brilliance is what allowed then to be as close as they were with the shit resources they had, but there are just some gaps that no amount of guile can overcome.And the illusion held up because the Soviets weren't really tested. The only conflicts they were really involved in was the Polish uprising and the invasion of Czechoslovakia, neither of which tested their military hardware. The USA really made huge strides in technological advancement after Vietnam, and then came the Soviet invasion of Afghanistan - that was a real eye-opener for the intelligence community. They were looking at each other thinking "can this really be happening? How can the Soviets be performing so badly?". But it didn't convince everyone the gap was real. After the fall of the USSR, the true breadth of the technology gap started to become a bit clearer, and then the west went into Iraq. Russia supported Saddam with weaponry and technology, and it was really the first test of modern eastern vs. western hardware - and that was really when the massive chasm became clear and the intelligence community realized they had been wrong all along, and the Soviets had always been many years behind from a technology standpoint.They are even further behind today than they were then.

We over-estimated them in some respects but that was as much because our military industrial complex wanted us to buy more of there stuff so they promoted the idea we were lagging behind them.The failure of the USSR to walk all over Afghanistan may appear to show the then Soviets were less than we thought, but the vaunted US has done what in Afghanistan in twice as long? How well did we fare against Viet Nam?If I take you logic then one might surmise the US is a military backwater because of the abject failure in Viet Nam, Afghanistan and Iraq.Just how well did the US intelligence agencies do with WMD in Iraq prior to the 2nd Iraq war?But, getting back to the competence of the USSR in military electronics the fact remains that in spite of there limitations and borrowing of this-that-and-the-other, they managed to build many weapons systems that were and are the equal of the west's best. There approach has always been different and in many ways that harms them, but in some ways it helps them. They were never able to compete rubble for dollar but they made the most of there more limited capabilities.Brian

content: Quote from: 6h8c on April 12, 2020, 08:26:21 pmThat EMP theory is mostly an urban legend.Realize that MIG25 was designed in the late 50s, with the first flight in 1964. So the reason the tubes were used in the MIG25 is simply because nothing else was available. Transistor has been invented only in 1947 and reliable mass-produced transistors did not arrive until late 60s/early 70s - and that was in the West, not in Soviet Union, hampered by embargoes! Also, the largest piece of electronics in MIG25 was the very powerful radar - - there you simply didn't have a choice because high frequency/high power transistors suitable for such uses didn't arrive until the plane has been retired (if ever!).So while the effect of increased EMP resistance is real (even though even vacuum tube electronics can get damaged!), it was mostly a side-effect of what was available on the market and not an explicit design decision. EMP resistance can be achieved e.g. by shielding, one would certainly not use vacuum tubes over semiconductors for this reason on a plane where every kilo of weight matters.The reason why 6c33c is still in those aircraft (it is apparently used in a power supply for a radio) is simply because the plane is long obsolete (manufacturing stopped in 1984) and if the planes were not refit with more modern gear back then, then today nobody is going to do it anymore.

Hardly something that you can install in a fighter jet that was required to operate reliably over a large temperature range (from -40C in winter to +60-70C in summer being fried by the Sun - common conditions in different parts of Russia), in vibrations, heavy g-forces, over years of use and abuse in field conditions (Russian approach to maintenance is pretty legendary - there are some good reasons why their hardware is generally so much beefier than comparable western one!).Also those P401-403 are hardly power transistors - the tube in question is a power amplifier tube, designed for 20-40W of output power, those transistors are designed for 20mA collector current if I am reading the datasheet correctly ...That something was manufactured doesn't mean it was also fit for purpose. Vacuum tubes were common in contemporary American planes as well (see e.g. the comment here:shorturl.at/EIVY7), for the same reasons. Heck, even F15, F16 and A10 (much never planes than MIG 25!) had vacuum tubes in their radars, because there were simply no semiconductors fit for the task.

Also, the military procurement has some particularities, like certification and the ability to obtain replacements even 20-30 years down the road. Tubes had all this established, those newfangled semiconductor things not yet.When it comes to mission-critical, humans-will-die-if-it-fails stuff, conservative and proven will always beat the new shiny.

content: Quote from: vk6zgo on April 13, 2020, 04:07:17 amYeah, the idea that transistors weren't available until the late 60's or early seventies is flat wrong. By the early 60's the leaders in the semiconductor industry were beginning to integrate several transistors into modules -- IBM had what the called MST back then if my memory serves me. By the late 60's early 70's we had the first large scale integrated circuits like microprocessors.Of course, the transition from tubes to semiconductors lagged behind the availability of comparable components because the engineers designing PCB's and other electronics had to have time to make the educational transition as well.In the mid 60's the USA manufactured something like 96% of all the worlds TV sets and at that time a TV set was built from discrete components with lots of wiring requiring lots of labor to build and then it needed to be aligned and adjusted which required lots more labor. TV sets of that era were very expensive. So, the US electronics industry looked to lower costs by outsourcing production to Japan and within a decade Japan was making the lion share of all the TV sets in the world. By that time the integration that TI pioneered in the late 50's had dramatically lowered the parts count and wiring requirements AND significantly reduced the alignment and adjustment costs as well. By the late 70's the US electronics makers were non-existent in the TV set industry having been REPLACED by Sony et al. When you un-layer that move what you realize is that the leadership of the US electronics companies was pretty dreadful and had they understood the impact of integration they would have know that the route to lowering cost and improving quality didn't require outsourcing but adopting integration.Brian

The issue is not whether transistorsas suchwere available but whether transistorssuitable for the taskwere.

content: Quote from: janoc on April 12, 2020, 08:52:13 pmIn the west very cheap high volume transistor radios were available at the beginning of the 60s. By the mid 60s most stereo systems were 100% semiconductor, mostly using discrete transistors. By the late 60s transistors and ICs had reached the stage where the only vacuum tube left in most TVs was the CRT. Your timing is way off.

content: Quote from: coppice on April 14, 2020, 11:40:08 amI'd push the transition from mostly vacuum tube to mostly solid state for new TV sets to a bit later than that. I knew three of the local TV sales/repair shops well so used to see the inside of more TVs than most youngsters (one was closest, where I used to go to buy components, one was run by one my father's only army mates and one was run by the father of a close friend at school). There were hybrid vacuum tube TVs being still sold at the start of the 70s (solid state tuner, vacuum tube HV section) and I'd put it closer to the mid 70s before all new sets reached the point where one could say with any confidence that the only vacuum tube in a new set was the CRT.

content: Quote from: Cerebus on April 14, 2020, 01:56:41 pmThe two major TV suppliers in the UK in the 60s were Philips and Thorn. The Philips G8 and Thorn 2000 were all semiconductor (except the tube), and both were shipping in volume in 1969 (although some historical sites say 1970 for the G8, but you had to be there, man). By about 1973 B&O were famous for the being the last maker with valves/vacuum tubes in their TVs.The TV models before the G8 and 2000 had a high semiconductor content. These were just the last steps in eliminating the valves. For comparison, the TV my parents bought in 1963 had a few semiconductor diodes, but no transistors at all.

content: Quote from: raptor1956 on April 13, 2020, 10:39:57 pmIBM started producing transistorized computers in about 1958-59. The 7094 was produced in about 1962-64, and had 55,000 transistors on 11,000 small circuit boards. This pretty much boggles my mind.Then, for the System/360, they produced SLT (Solid Logic Technology) which were 1/2" square ceramic hybrid modules with generally 2 transistors and 4 diodes, plus 4 thin-film resistors. They made many millions of these SLT modules. The System/360 was introduced in summer 1965, and started shipping late that year.MST was Monolithic Solid Technology, and was used in the 360/85 in 1968 and the model 195 in 1969, before coming outin all the 370 models in 1970. It was VERY similar to Motorola MECL.Jon

content: Quote from: jmelson on April 19, 2020, 03:30:13 amWhen I worked at IBM East Fishkill, 1982-1993, they may still have been making some of the devices as they had quite a few old and small manufacturing lines in operation. When I started they were still making chips using 57mm, 82mm, and 100mm wafers. For a long time IBM went there own way and when the industry was at 50mm IBM squeezed 57mm out of it -- similarly when the industry was at 75mm IBM was doing 82mm. By the time 100mm rolled around IBM realized they were paying too much for the marginal gains.When I started in 1982 the feature sizes were still above 1um so they could still tolerate the kind of particulate issues that a decade later would have destroyed 100% of all chips so we began to investigate methods to reduce the particulate levels in our 4-stack horizontal Tempress furnaces used for oxidation and diffusion processes. At the time the wafers were put into quartz boats about 25-50 per boat and then those boats were put onto a quartz sled and the sled, with about 200 wafers, was then pushed into the hot zone of the furnace with a quartz push rod. We used a half-step stepper motor system to push/pull the sled at about 5 inches per minute to avoid warpage. One of the engineers calibrated the control in units of 'furlongs per fortnight'. The solution to our problem with particulates was to eliminate the quartz-on-quartz sliding of the sled in the quartz process tube by using a cantilever paddle. Not long after we began working on this project the mechanical engineer that was designing the test fixtures was accepted into the IBM advanced degree program (forgot the name of it) and he left -- I was put in charge of completing the design and testing and in the end the solution we came up with was the same that just about everyone else in the industry came up with -- the Norton Crystar SiC paddle. By the late 80's or early 90's the first of the vertical furnaces came out with built in wafer handling automation and the days of the horizontal furnace were numbered. I left IBM about that time and joined SVG (Silicon Valley Group) which made, among other things, vertical furnaces. Before SVG, which by then had been bought by ASML, went out of business, they were producing a new class of tools called ALD for atomic layer deposition -- basically you puff small quantities of reactants into an evacuated process tube and can produce films a single atomic layer thick.Brian

content: Sticking to the 'Topic' description... (people that know me know how important that is to me! hahaha)...As an 'old' bastard, (or old 'bastard'!) and into old valve/tube equipment, I've always loved certain old Russian equipment/components!!Yes, they were often built cruder, but always (seemingly to me), more robust! Meaning that they lasted, especially with physical abuse.In regard to todays modern electronic components, I've always wondered about the following...Inside I.C's, (even to a point with SMDS), they make the ACTUAL chip say typically about 2mm square. Obviously, this has to be EXTENDEDinternally to wire it to tiny little wires to the normal size (and solder-able/accessible) typical IC casing/pins. I understand that either today, orin the future, there are/maybe numerous quantities of individual IC's all built into one, but why so small? Why would the cost of a silicon waferbe so high with it's associated component design/integration, when in the end it needs to expand to physically usable dimensions?

content: They are not "extended". They are wire bonded to a lead frame which contains the external leads, before encapsulation. In more modern technology the die is soldered face-down onto an interposer using small solder bumps.The reason a die must be as small as possible is cost. Fabricating each wafer is a fixed cost, no matter how big or small the chips are. Smaller dice means more dice per wafer,andhigher yield of working devices, since the randomly located defects on the wafer affect a smaller fraction of the total devices. If chip A is half the area of chip B, it will be about a quarter the cost. This is also the reason that the most cost-competitive CPUs use multiple "chiplets" per interposer in MCM (multi-chip module) arrays. The economics is vastly better than large monolithic chips with the same functions.

content: Quote from: helius on November 07, 2021, 08:18:32 amNot really. If both dies are small enough (for the process maturity) they will cost almost the same for the area used because the percentage of defective dies will be small in both cases. Also it depends on process maturity and if defective parts of the chip can be disabled (cores, cache, etc). Many chips are already produced with spare functional blocks. For example all PS3 SOC had 8 SPE but only 7 were used for better yield. All modern DRAM has spare rows and columns. 2x size for 4x the cost will only be true if silicon die is very large, defective parts cannot be disabled and manufacturing process is not mature enough (low yield). Nor this makes any sense mathematically. For example you make 2 chips on the same process. One chip has 16 times larger die area (2^4) that other. Then larger chip should cost 256 times (4^4) more according to what you said. Which would mean 16 times higher cost for the same die area. It could only be true only if for the larger chip the yield was only a few %.QuoteAlso not entirely accurate. When chiplets are used, the modern, immature and more expensive process can be used only for what it's actually needed and the rest of the chip can be made on an older and cheaper process. For example Ryzen CPUs use 7nm process for smaller CPU core chiplets (often there is only one such chiplet) and 12nm or 14nm for larger IO die. Not only they save the money because of better yields, they don't need to produce different masks (extremely expensive) for different CPU models. But when it comes to laptop CPUs, the same AMD does not use chiplets and makes a much larger die on a latest process because it lowers power consumption compared to chiplet design.

content: I was working with people from one of ex-soviet microelectronic enterprises.They was able to make chips @ micrometers-scale technology in late 80thAfter listening a lot of stories from old engineers, It is hard to believe that soviet microelectronics not died before Soviet Union died itself.Management was terrible!They had Comsomol committee (Youth communist organisation) unit in their organisation. these people did literaly nothing, but recieved all prises and benefits.For example, if any group of engineers made some advance (invent or optimize something, wrote an article etc), some of these communists arranged himselves to become "team leader", and patent or journal article had to be registered under his name first.So real engineers hadn't any stimulus to hard work or make any advance.Also there was inequality in wages for engineers and workers.For soviets, workers should be respected much more than engineers.For example in this enterprice in 80th, machine operator's (with no college education) salary was about 500 Rubles, and they was allowed to take longer vacation, every year thay received free vouchers for traveling to resort.But engineer's (with high education) salary was about 300 Rubles, and they was forsed to overstay everyday, and has less benefits than workers have.Also it was very hard to fire a worker. In a case when worker did something wrong - most of responsibility and penalties had to be placed on engineer. So workers was disrespect engineers, and engineers feeled very insecure: in any disput or conflict at work, a worker has more advantages.I don't know correct equivalent of this term in English, direct translation is like "Electronic-vacuum hygiene rules".It is set of rules for personel stuff on how to work in clean-room dust-free environmet and how to keep environment dust-free enough for manufacturing of microelectronics.They was not able to obey these rules. Not because of limitations in technologies, but also because of problem with management.Some funny stories:- each team every morning received about 200ml bottle of ethanol to clean workplace surfaces.How do you think, how much of it used for drink?- Female workers was banned from use of any cosmetics (face powder, eyebrow makeup - all add dust) . To ensure it, management even prohibited all mirrors in the entire building (so girls can't look into a mirror and apply cosmetics).But girls from Comsomol comittee (or somehow related to it) was allowed to use cosmetics, moreover, they even was able to not wear protective hats and was show off her hairstyle:)All girls used cosmetics and not weared hats at night shift.- There was "scientific" term called "Night shift problem". All crazy things that can happens in manufacturing process, usually happened during night shift. Mostly because there was much less supervising personel at night. Every morning engineers goes to work with fear to realise that yet another "Night shift problem" happened last night.

Many westerners still don't realize the danger of what is to come.The people from the Eastern European countries keep telling them the danger, but nobody registers because they don't yet experienced what is to come. The Eastern Europe already lived through this before. The western world don't realize that the so called democracy, in the current times is no longer a democracy, in the sense that if you speak your mind, and name the things for what they are, you'll be either marginalized, or arrested. What is happening to the western world now, is a totalitarian takeover. It's Bolshevism 2.0, but the westerners are too obedient and too scared to stand together. Last time the maneuver mass was the working class. Now they use emigrants, and puppet politicians.Spoiler alert from the soviet times, for what is to come for westerners, too, if we don't push back:- nationalization (the Marxists/communists took the factories, the land and other business; for some reason this reminds me of some USA states that recently changed their laws to not really punish shoplifting for less than $1000)- expropriation (they took the ownership of everything, including houses, and for those who were heaving more than one room, they brought other people to live there. Though, the owner was often removed from the house, and put to leave in a shack or in the dungeon or the attic of own house. It was mandatory to host squatters in every room, as permanent residents; this situations reminds me about some recent laws about squatters, and hotels given to illegal immigrants)- self policing and deportation to gulags (the newcomers were feeling very entitled and righteous for being from the working class, and they were thirsty for "justice", so they rat on everybody. First they rat on those who were better than them, then they rat on each other. Everybody became "an informer", and it was not unusual to get rid of the competition by anonymously "reporting" them as anticommunist. Sometimes, this was happening even it in the family. It was easier to rat a spouse as anticommunist, than to get a divorce. And it was not unusual for some brainwashed kids seeking a teacher's appraisal, to rat on their own parents, sometimes with entirely fabricated plots so ridiculous that not even the communist activists believed them; strange thought coming in mind about the English people and how they can get arrested in their own country if they complain online about illegals stabbing and raping, next step, straight to gulag)- mass brainwashing propaganda (people was indoctrinated to hate everybody that was not from the working class; not much different from the nowadays DEI anti-white propaganda at office, queers in schools, guilt tripping everybody with green agenda, and other ideological subversions, like women seen as workers instead of being seen as mothers, promoted miscegenation, breaking traditions and family, encouraging promiscuity, to name only a few).For the manufacturing of components during the soviet times of the communist Romania (technically the country name was the "Socialist Republic of Romania"), just like the soviets, we used to make many electronic components, but not any more.These are data book catalogs with Romanian made components during Ceausescu's regime, 3 of the biggest companies of that time, ICCE, IPRS Baneasa, MicroElectronica, now all gone:- ICCE - industrial IC -https://www.scribd.com/document/701433130/Icce-Catalog-Databook-Componente-Electronice-Semiconductoare-1980- IPRS Baneasa - passives, transistors, analog IC, radio/TV parts, digital TTL -https://www.electronica.ro/full-line-condensed-catalog-iprs-baneasa-1990.shtml- Microelectronica - CD4000 family, Z80 processors, memories and other MOS digital IC -https://www.datasheetcatalog.com/microelectronica/1/A very, very brief, one page long overview of the electronic industry in Ro, during soviet times -https://en.wikipedia.org/wiki/Electronics_industry_in_the_Socialist_Republic_of_RomaniaThere are many spicy story of how the eastern block was trying to overcome the technological gap, by either buying or stealing technology. Not talking about patent infringements, but also about industrial espionage. It was happening on both sides. One of the most known here in Ro, are the tails told by Pacepa in his book about Romania and Ceausescu family, but the tails are also talking about industry in general, and about electronics, IC and computer industry. Pacepa was the head of the Romanian secret service during Ceausescu, and he defected to USA in the 70s.https://en.wikipedia.org/wiki/Ion_Mihai_PacepaLater, Pacepa wrote a book, "Red Horizons" with a chapter (https://archive.org/details/redhorizonstrues0000pace/page/n7/mode/2up) about electronics, Romania and Texas instruments, and other spicy spy stories about the eastern and western blocks at the time. I've listen to the Romanian version of the audio-book, and found many details that I have lived through, so I assume the book is correct, not fabrication. Good read, gives the vibe of those times.

I've thought for a very long time that they have been actively working to destabilise the West by sponsoring and influencing -- even instigating -- organisations such as Greenpeace, Occupy, BLM, Antifa, Extinction Rebellion. We've been learning very recently of the extent of their operation to pervert conservative commentators in the USA, especially to get them to speak out against defending Ukraine as free people everywhere very obviously should be. As someone who is libertarian/objectivist I'm naturally more sympathetic to economic conservatives (despite their often unpalatable conservative social policies) and it's been very upsetting recently to see their leaders appear to be siding with Russia against Ukraine. I hope this will change, and before they win the coming US elections (or very soon after!).

content: As an ex Army officer with a background in missiles, I would dispute the comments stating that Russia is on a par with the west in that area. I have been watching the coverage of the war in Ukraine with interest. Either they are completely holding back their better missile systems or they are at least a decade behind, probably two.There is evidence that their most advanced air defense systems can not even protect themselves, much less other targets in their assigned area.What I see is a reliance on western technology that they somehow obtain in order to build showcase systems but they can't actually produce those systems in the desired quantity due to lack of sufficient supplies of those components. Their scientists may be good, but it ends at the R&D(of one) stage.Other areas of weaponry show the same problems. At one time I feared their numeric advantage in tanks. Can you say "Pop goes the turret?" They actually store the tank ammunition under the feet of the crew, in the same compartment. At least it's merciful, there is no time to suffer or even know what happened. The Kalashnikov assault rifle (AK-47) may be a great rifle, but what has followed? And the flag ship of the Black Sea fleet was sunk by a country that has virtually no navy. Their ONE aircraft carrier could not leave port without an accompanying tug boat and now can't leave port at all. The list goes on and on. It is hard not to laugh out loud. But I am not making fun of them. Just my view as an ex-ordinance officer.And what about their nuclear weapons. If I were a Russian general I would not dare to launch one for fear it is as likely to land on Moscow as Kiev.They are good at bluster but can't back it up with real weapons that get the job done. And I suspect that China is much the same.

content: Back on topic then.One popular story is that the Soviet chip industry was created by the two EE guys from New York. They became a Soviet spies, eventually fled to USSR and started to work in the defense industry there. Soon they were noticed by Sergei Khrushchev a son of the Soviet leader at the time, who was working as a EE on a defense projects. He was inspired by the guys and advised his father to pay attention to them. That resulted in the government decree to set up a dedicated industrial hub near Moscow, one of the guys, Alfred Sarant was assigned to be sort of CTO there and this is how the microchip industry was started in USSR.https://en.wikipedia.org/wiki/Alfred_Sarant,https://history.computer.org/pioneers/barr.htmlSounds like a Superman story. But a more serious information on the subject is actually difficult to find, few documents are available. So it can be interesting to read interviews with the insiders. One of the following accounts is from a son of the minister of the electronics industry of USSR, who was also active EE at the time. The other is from Zhores Alferov, a Nobel prize scientist, who provided an overview of related scientific research in USSR back at that time.https://www.computerhistory.org/collections/catalog/102746435https://www.computerhistory.org/collections/catalog/102746430

To my knowledge there is no russian manufacturing plant for wafers/ICs of halfway recent transistor size, so manufacturing has been done in Taiwan, maybe now China, for many years. The newly invented russian CPUs were (AFAIK) all manufactured in Taiwan. I assume there may be 100nm small volume production though.As for hiding some super-uber-weapons - I don't believe so. The S400 are quite "good" (in a technical way), and probably only a few years behind Rheinmetall - but they are extremely complex and slow to build. So I don't think they are holding them back. However a lot of equipment might have been reserved for the protection of important targets (Putins home complex is rumored to have several air defense systems installed e.g.)
