Overview

The video traces the origin story of Demos, a Soviet “Unix” system, and how it became tightly linked with the first Soviet email/network connections to the outside world, culminating in its unexpected role during the August 1991 coup.

Early “hoax” and the idea of crossing the Iron Curtain (1984)

  • On April 1, 1984, a message appeared on Usenet claiming the USSR had joined the network for “peaceful dialogue.”
  • It was signed with an absurd Kremlin-themed hostname ending in “Kremvax” and “KGBvax.”
  • The prank is described as designed by Piet Beertema (a Dutch pioneer).
    • It worked because, at the time, crossing the “Iron Curtain” via international networking was considered unthinkable.
  • The video frames this as a kind of prophecy that later becomes reality.

How Soviet “Unix” became possible: cloned hardware + embargo workarounds

  • The USSR is described as choosing to clone Western computer architectures rather than build entirely new ones (e.g., ES clones of IBM 360/370, SM clones of PDP-11).
  • This cloning made it possible to run Unix-like systems because an equivalent Unix environment existed conceptually.
  • However, Unix was blocked by:
    • U.S. licensing (AT&T), and
    • the technology embargo (CoCom).
  • Despite official barriers, the video explains that Unix source fragments circulated in Moscow via tapes—through academic travel, black-market channels, and/or theft.
  • A key claim is that the KGB was not credited as the main driver of Soviet Unix; instead, it was primarily students and researchers.

Two Soviet Unix projects, rivals in name but merged in practice

MNOS (from 1981)

  • Originated in an institute tied to the Ministry of the automotive industry.
  • Derived from Unix Version 6.
  • Praised for being small and fast, including an affectionate nickname: “Rabochaya Loshadka”.

DEMOS (from 1982)

  • Started at the Kurchatov Institute (associated with the Soviet atomic program).
  • Derived from BSD (Berkeley branch), emphasizing portability (described as “Mobilnaya”).

Convergence into a unified family

  • The video says the two systems effectively converged:
    • patches and people were exchanged until
    • by 1986–1990, they were merged into a unified system family.
  • It describes DEMOS 2 as based on 2.9 BSD, later moving toward 4.2 BSD for 32-bit machines.

Technical highlight: Cyrillic support designed for “hostile” conditions

  • The video spotlights Cyrillic handling as a major innovation.
  • MNOS is described as the first fully bilingual Unix.
  • It reportedly used KOI8, an encoding designed so that if the eighth bit is lost (e.g., modem errors or Western systems), the text still degrades into a readable Latin transliteration rather than unreadable garbage.
  • This is presented as engineering “for a hostile world” and unreliable communication lines.

Soviet state recognition and perestroika’s effect: commercialization of Unix

  • In 1988, the DEMOS developers reportedly received an official USSR Council of Ministers prize—despite Unix being tied to embargoed Western technology.
  • Perestroika (Gorbachev-era reforms) is presented as enabling the creation of private cooperatives/companies.
  • A Moscow cooperative (initially “Interface,” then renamed the Demos Cooperative) sold and supported Soviet Unix as a commercial product—portrayed as extraordinary in 1989.

Building the Soviet network: Relcom and the first exchange with the world

  • In summer 1990, the Demos Cooperative and the Kurchatov Institute built an email network using UUCP.
  • It was named Relcom (“reliable communications”).
  • On Aug 1, 1990, Relcom connected Moscow with other Soviet research centers (Dubna, Serpukhov, Novosibirsk).
  • On Aug 28, 1990, the USSR connected to the world via an international modem call to the University of Helsinki, repeated hourly—depicted as piercing the Iron Curtain using ordinary phone infrastructure.
  • On Sept 19, 1990, the top-level domain .su was registered.
  • The video notes that when demons.su / demos.su-related messages appeared on Usenet, many people treated them as another prank, echoing the earlier 1984 “Kremvax” hoax.

Usenet identity and the “Kremvax” punchline

  • The video claims the Soviet Unix User Group introduced itself as real, with early users repeatedly asking for confirmation.
  • The chief programmer, Vadim Antonov, reportedly signed posts with “Demos, Moscow, USSR.”
  • The video says Antonov used humor by naming the gateway host after the Kremvax prank hostname—turning a joke into an actual system name.

August 1991 coup: Relcom as an emergency information lifeline

  • During the August 1991 coup, coup plotters allegedly tried to seize control of information (shutting media, cutting off external feeds).
  • The video’s twist: Relcom still worked because it wasn’t treated as “mass media.”
  • For about three days, Relcom transmitted:
    • Yeltsin’s decrees declaring the coup illegal,
    • eyewitness reports from the streets,
    • news bulletins,
    • to the world via Usenet/news distribution.
  • It reports approximately 46,000 units of news exchanged between the USSR and the outside world during that period.
  • A quoted anecdote emphasizes fear inside Moscow:
    • Antonov’s wife wrote they were “frightened and angry,”
    • and that tanks and shutdowns had not stopped Relcom.

Aftermath: fragmentation, Linux, and the surviving .su domain

  • The Soviet Union dissolved soon after; the cooperative evolved into a business and eventually fragmented.
  • The original Demos system is described as declining quickly once Western hardware flooded in, alongside the rise of new Unix-like systems (including Linux, credited in the video to a Finnish student writing in roughly the same era).
  • The .su domain is highlighted as a rare survivor:
    • registered in 1990 and still active decades later,
    • with over 100,000 registrations,
    • though it’s portrayed as having gained a “shady” reputation (cybercrime refuge).

Conclusions the video draws

  • The story is presented as evidence that code and knowledge can’t be fully contained by borders: embargoes and licensing limits were eventually bypassed.
  • It frames Unix and networking as tools that connect people precisely when authorities try to isolate them.
  • Final remarks connect “free code” today to the earlier reality where it had to be treated like contraband to be shared.
