This was a fascinating article, because I've seen so many results of the Eastern Bloc reverse-engineering efforts basically founder into obscurity. Many of these re-created (sometimes with minor variations, or quite novel and ingenious implementation choices) computers were made in small series, but could not compete against illegal imports, and in any case would only be briefly popular in their local university town.
So it's cool to see that Bulgaria managed to muster enough government interest to force a cohesive strategy for the whole country. It sounds like it paid off.
Also, after googling for Правец, I have found out that I can in fact read Bulgarian, which was quite surprising to me.
>could not compete against illegal imports
How could that be possible? Imports had to be made in hard currency which was incredibly scarce in the Soviet Bloc (a VCR cost couple years of engineer's income on a black market), and was hard to obtain both for official/communist enterprises, and private individuals. Locally made stuff was bound to be a lot cheaper.
Quite a few words in Bulgarian are similar to words in other European languages, just written in a different alphabet. I briefly dated a girl in Bulgaria years ago and was surprised at how quickly I could find my way around by reading street signs, applying knowledge of French and German, etc.
The author asks why did the communists always clone things despite having engineers who could have designed their own? You don't need an LLM to answer this. The book "Chip Wars" is a really good history of Silicon Valley and has a section on the Soviet chip industry, how it was structured and why it cloned chips instead of designing their own.
The Soviets didn't just clone computers but most of their advanced tech. Partly it was just mandated top-down. You had dictators at the top who were there, as the author observes, because they were just more aggressive and swivel-eyed than anyone else. They mandated cloning, so cloning is what happened because everyone was afraid of them.
But that doesn't really answer the question. Cloning things isn't just an attribute of one specific set of leaders in the Soviet era. All communist countries are like this. Western AI labs keep claiming the Chinese labs are distilling them like crazy, and we know Anthropic has anti-distillation measures hidden inside Claude Code so it's not just a PR thing, they do believe it's happening for real.
It always happens because leftism rejects the role of the capitalist in society. Capitalists are workers whose output is voluntary coordination across complex projects. If you kill them all then you have a society that's unable to create voluntary coordination across complex projects. The immediate consequence is that the economy goes haywire because without capitalists nobody knows how much or what to produce; the USSR solved this by having spies steal price lists. But you also can't run a novel chip design programme. That would require finding the right people with the right skills, encouraging innovation by giving them a cut of the rewards, and other things you aren't allowed to do in leftist regimes. So ... they just couldn't produce voluntary coordination. And thus to get anything done outside the military they had to steal the output of western capitalists by just copying whatever their teams were doing, down to the last detail.
Bulgarian is phonetic to a large degree so if you know the sound associated to a letter, you can understandably pronounce it as well.
Regarding communism and computing, deterministic systems where the entire state is knowable and predictible have certain appeal for the communist mind. If you search in the HN archives, you might find even more stories about the bulgarian computer industry with a MIT publication in the mix. There could've been even more, but a combination of distrust towards the new capitalist science and later unwillingness for those pesky machines to show the real state of the USSR economy meant that this was not developed with the full backing of the eastern block.
Well... The rusian Spectrum clones had some sucesfull career. And they did a lot of improvements over the original Sinclair and Amstrad designs. The Pentagon and the Scorpion with extra RAM, or the ATM come from pure rusian ingenuity .
