    The PDP-11 at the Air Force Academy read its programs from paper tape. I remember the only tape that we used (Lunar Lander) taking 43 minutes to load. :)

      The datasette I used with my Commodore 64 had similar loading times. If you wanted to play, say Pac-Man, you literally had to sit for at least 30 minutes before the whole thing was loaded. And heaven forbid if the magnetic head was slightly misaligned. It would reject the load - and always just before it was about to finish - and you had to start all over again. Those were the days...

      @@swokatsamsiyu3590 Without fastloader, a 30 minute tape for the Datassette holds 100 KB, which won't fit inside the 64 KB RAM of the C64. People talking about the Datassette tend to exaggerate the loading times. For small and medium sized files and with fastloader, the Datassette is a totally usable device.

    It’s such a shame stalkers, marauders, and other thieves and looters literally ripped apart the places in and around Pripyat…
    I would have loved to take a tour through the entirety of all the places, especially the Duga computer rooms in the late nineties through early 00’s…
    Edit: I’m sure that even after the MoD moved much of the equipment to the installation in the Far East the place would have been quite a joy to investigate!

      I often think about this. Even in last 5 years things deteliorated significantly.
      Well, we will have a very detailed documentary on Duga, including a very concrete talk about its computers, with recreation of some of its parts; we are doing a research of it more than 5 years, and could recover much information from what remained on site. It will be released in the next few months, as the work needed is really massive.

    OMG what a trip that tape deck is! Those bypass caps are just the best! It's too bad Stalin declared digital computing degenerate. Had the USSR embarked on a real program of building their own in house computers and integrating them to society, the Sov Punk that would have resulted would have been freaking awesome! I can just imagine the alternate history where the Soviets did everything the West did on a wide scale with the same touch we see in this tape deck. You can imagine a world where nations like India and Egypt become flush with Soviet computers. And instead of MiG diplomacy the Socialist Bloc and the non aligned nations would be running on Soviet computers, networks and software. This made by day with its general awesomeness.

    • @ChernobylFamily

      Well, that was not Stalin, but Khruschew, and not digital computers, but cybernetics. However, there was an epic page of our computer history - OGAS system project by Viktor Glushkov, founder of the Institute of Cybernetics in Kyiv; that thing was so ahead of time, and so dangerous for communists (as they would not be needed in algorithm-driven USSR as he envisioned) that he received a resistance of it up to his death in 1983.

      It’s so sad because at one point Soviet computing was far ahead of the west, but the expense and effort wasn’t appreciated, I could imagine an incredible world of technology had the soviets kept up their development, it would have provided impetus for western companies to try harder and could have spurned development during the stagnation periods in the 70s and 80s that slowed the development of more advanced technology.

      @@ChernobylFamily I think it is a clone of the PDP-11s architecture, I just wasn't expecting how similar it is to the real thing. I just thought it was interesting. QBUS was a DEC technology used on those systems as their backplane to connect all the cards, the cards then had connectors on them to run ribbon cables to the rest of the computer. Card cage is the word used over here for what you referred to as crate. Very interesting to have a disconnect like that. You don't have to change what you say, it's just interesting.

      @@JenotplI will be honest, I did not check the type specifically when I was crawling over those racks; IF those are 1420 which they look as, then yes, those are from Elektronmash factory in Kyiv. Could also be 1810 as well, those are not PDP, but Intel-based, also Kyiv-made. In fact, wast majority of specifically PDP-11 line of SM machines were made in Kyiv.
      As for dual-processor setup, as far as I remember, there is one processor module in the machine, BUT, there existed СМ 1420.21.22 which was a dual-machine system which would act as dual processor. A pure dual-processor is a Lithuanian СМ-1600; For now I do not have any documents that prove the use of 1600 in Chernobyl. CM-4, CM-1420, CM-1800, CM-1801 were used widely.

    Very interesting to contrast the very crude tape mechanism and front panel (no labels on the eject and write protect buttons!?) with the fan power connector. The power connector has a metal back shell and so many huge pins that look machined. Many US computers I've seen of similar age either use a very basic plastic connector or even just solder wires to the board.

      Indeed, GOSPLAN doesn’t care about ergonomics or UX and GOST standards were probably too generic to force manufacturers away from sacrificing everything in the name of the Almighty Quota but the Army being the biggest “customer”, they could’ve had the influence to ask for it. Which yes, would work… how should I say - “around the rules” (like most things that actually worked back then :))))) of the planned economy. Except that they had no need for ergonomics or user friendliness.

    Gosh, thirty kilogrammes - that's a brute of a machine! Fascinating (and nostalgic for oldies like me) to see the interior. The front panel may have Lada tech but it looks very elegant.
    I found your remarks about socialistic design very interesting - do you think that perhaps product design of that period were deliberately kept very basic because luxury or convenience was considered decadent and 'Western'? In other words, was the design philosophy something like this? "Convenience and luxury in a product makes the user lazy so if things are harder to use it encourages the user to be tougher and more diligent." It's just the thought of someone viewing from a distance. Thanks for the vid and love to you both. Peace soon.

    • @ChernobylFamily
      @ChernobylFamily  ปีที่แล้ว +4

      Thank you! I'd say the trouble of design was grounded in a planned economy and over-formalization of everything. There were cool ideas of 'technical esthetic' (a term used for 'design' in the USSR), but an obstacle for them often was a lack of what the plan-controlled industry could produced. A substitution after a substitution and we come to a crude boxy thing. There were exceptions though.

    • @tomfu9909
      @tomfu9909 ปีที่แล้ว

      The reason for design in capitalism is a competitive advantage. In planned economy, your sales are planned, your competition is nonexistent, so what reason you have to spend money for design and precise machining of let's say front panel of you device? Sadly it doesn't end with design of aperance of the device.

    I like your comment about the eject. Over here in the US it was a kind of sign of quality if something had a very very slow tape eject mechanism, and if something just sprung open, it would've been thought of as something cheap. Of course, by some point you'd get a bunch of poorly made junk with overly damped eject mechanisms. :p
    Also that MK-90 I got is working out well. Ordered parts to build up a flash cart for it so I can load stuff on to it, and i've started writing code for it and testing in an emulator, but I'm wanting to see how well things work on real hardware. Have some graphics routines working so soon I can make a game for it.
