This reminds me of Asianometry's videos on Soviet computing history plus videos about weird 80s and 90s laptops. It's definitely something I'd love to see more of, hence why this channel is one of my favorites. It's rare we westerners get to have a real look at what you guys had. Schools here hardly talk about early computing history and definitely completely gloss over Soviet computers, which is a shame because it's equally as impressive despite the Soviet computers having completely different standardization to western and east Asian ones and ultimately having to be abandoned due to that. I have to wonder if schools in former Soviet states even talk about Soviet computers or do they also only talk about western ones?

Pretty neat that there were probably only ~1500 of these. I liked your little rant about how metal scavengers should’ve just resold them for their intended purpose.

*Дякую* for this video sir, and especially for the finely detailed teardown! One thing I've always had trouble finding is the Soviet Cyrillic keyboard layout, and thanks to this vid (And a couple of screenshots) I _finally_ have what I was looking for in this regard! ⌨🇷🇺😀 Rare as this is, I sadly doubt very much that original replacement parts for the power supply still exist anywhere (Especially if they were laid on gold, because $$$s) but many years ago I ran into a similar problem with a laptop of a roughly similar vintage, and for testing purposes I used various series/parallel combinations of alkaline batteries to produce the correct voltages. It was an absolute pig fitting it all on the bench, but it was enough to test out the laptop and prove that it worked! 😇 Assuming the service manual gives the voltages for each of the rails coming off the PSU (And let's face it: One of the reasons why I love tech from the USSR is because it was _designed_ to be user serviceable! 🛠) a battery array might work for testing, but for continued use some of the off-the-shelf PSUs now available in the market should be able to provide the correct voltages to keep this beauty running safely! 🙂 And OK, it might not be the _best_ computer of its time...But unlike any of the British made computers of that era I wouldn't be surprised if this - Once fixed - Would continue to work for a good 200-300 years afterwards! 🤘

From my experience with twisted nematic displays like this, the solid blue screen is likely just the contrast cranked all the way up. The artifacts on the LCD look to be scratches in the polarizer film from somebody drawing on it with a pen or something. If you can find a junked donor LCD, even a modern one, you could probably trim to fit and get that fixed. As for the backlight, you'll likely need to get the -15v rail working on the power supply, or connect an external supply long enough to find out if the CC tube is still good. The 60-pin internal expansion connector is likely an ISA bus if this is a true XT-compatible clone, so you could probably design a CF-IDE card for it if you can find a pinout. As for the power supply... Eh. I don't even know where to start with repairing that, especially without schematics or even knowing what those missing components are. Personally, I'd just build a new one from scratch, as DC buck converters and voltage inverters are inexpensive, and easy to use. That might not be a "proper" restoration, but it would at least be functional. Sometimes you just gotta do what you gotta do.

There could not be soviet drives - they did not exist as a mass product.

Hmm, very interesting machine, thank you for your very well made review! It shows how much effort had run into the basic hardware layout, if the chips are genuine russian made (which I assume). The AMI Bios makes sense, to keep it IBM PC Compatible and thus open to the world of programs. All in all not shabby, a 386 was ok in 1991, not the cutting edge, but good to work with. If it had been developed further to make it more affordable and the international PC world wouldn't have gone that crazy cheap for used machines, it could have become a success story as well.

That’s so cool to see! I had a Tandy 1400 LT which looked like this. It weighed a ton, the battery lasted maybe an hour, and the display was similar. The Toshiba laptops were much nicer. That would’ve been 1991 or so.

Yes. Technically, the laptop in question is not russian, it is from Belarus (it does not make it any better, just we, who lived in other republics under FORCED umbrella of the ussr, find calling all with words "russia" pretty... not good)

Removing the keyboard ribbon included a reference to the Demon Core? Oh my.

I never saw a DIP IC with two holes on it (except for mouse optical sensors). I imagine the reason for that, like for them to be attached to heat sinks for instance. There is a so big contrast between the quality of the motherboard and the quality of the power supply that I question if the it was sourced from already existing projects.

Those are for positioning during production, it is manufacturer-specific thing. They do not serve any other purpose.

I'm curious about the keyboard, as are some people I know in the keyboard community. The switch mount on the pcb resembles Mitsumi miniature mechanical, but it's soviet, so it can't be that. Any way to show?

You know, if the expansion port is basically an extension of the ISA bus, there might be a noninvasive way to attach a modern fixed disc solution like the XT-IDE. Tex-elec has a very tiny card that would fit nicely in that unused battery compartment. Figure out the pinout, have the right sized card edge made (maybe PCBWay), and then solder a ribbon cable on and route it into the battery compartment. As far as the PSU is concerned, I know the Amiga community swears on the Mean Well PSUs. I'd put it in an external enclosure, make a new expansion plate and solder in the multipin connector of your choice and build a matching cable to the external PSU. Basically adapt the Amiga solution to the computer. This assumes the scrappers trashed the orignal PSU beyond repair. Regardless, I bet you could fit a battery holder (say, 3 triple As) in that battery compartment to power the clock chip and get it on a more modern DOS variant. All in all kind of a slick computer.

You'd need more pins for an ISA bus though, wouldn't you? :(. The Amstrad PPC uses a DB25 and a DC37 connector to present the full 62-pin ISA bus, and the Visual 1083 Commuter I'm working on at the moment uses a DC62. There's probably just enough pins on a DB25 for a floppy interface though. /Brett

@@Brfff Minuszerodegrees has the maintenance manual for the T1100+ for download which includes a pinout of the expansion bus connector. It's a 60 pin connector that seems to carry the full ISA bus. Also there's at least 1 guy on r/retrobattlestations that adapted the XT-CF card to the Toshiba expansion bay connector, complete with 3D printed shield for easy swapping of cards. He was also mooting the idea of building a combo card that added an Adlib card. You could also add a ram expansion, too. Cramming all of that would be challenging but would be worth it if only to play Tetris on a Soviet PC clone at a coffee shop in Kiev or Lviv!!!

Although, watching on ... there is that 60-pin internal interface ... is that the one you're referring to? If you could find the pinout then definitely, you could conceivably design an interface board (XT-CF-Lite) that plugged directly into it ... and it wouldn't matter if it were Soviet 2.5mm or Western 2.54mm pitch as you could design the PCB to fit either. I'm doing similar for the Amstrad PPC at the moment, trying to cram an internal CF board inside the machine. /Brett

Nice to see one disassembled, I knew about it's existence and that it was a clone of the early Toshiba laptops, but I never realised how much similar they are even inside - having repaired T1200 some years ago this looks almost identical layout and plastics wise.

@@ChernobylFamily It looks kinda similar, but i don't have it here by me so I can't check. I know that schematics for these old Toshibas are online so it might be worth to take a look. Also these Toshiba PSUs are notoriously unreliable so I would suggest only comparing the pinout, not actually looking to buy one 😁

Serious question though: are all the board-mounted components hand soldered or did the Soviets have wave soldering and pick and place tech at that time?

@ChernobylFamily

I believe at top factories they had pick and place, logically they had to. Though I am really not sure. Sometimes it is very much visible when it is really hand-soldered.

Kiev 'Elektronmash' did have wave soldering. And there was domestically designed DIP chip placement machine named 'AVUMIS' (Rus.: "АВУМИС", "АВтомат для Установки МИкросхем" = 'automatic chip placement machine'). The name is kinda pun on 'VUM' ("[завод] ВУМ") which is another name for 'Elektronmash' of Kiev.

Интересно, МС 1504 это функциональный аналог Тошиба Т1100. Видел ролик на Ютьюб, как умелец сумел запустить на Тошибе windows 1.0. По идее и на МС 1504 это тоже должно пойти, но почему-то никто не пробовал до сих пор

I have a feeling whoever stripped those chips from the PSU didn't own the whole device to sell intact. If it was someone working in the warehouse where the laptop has already sit unopened for months or years, they must've thought it will never be sold. So there is no harm stripping out some interesting components and putting the rest back into the box. Nobody will ever notice because it will rot here the warehouse until clear-out straight into a landfill. Still, they wouldn't dare to just steal the whle laptop and leave behind an empty box because that would be too obvious during inventory.
