First attempt to wire up the 300 Kg HDD of Chernobyl SKALA

  • Welcome to the continuation of our exploration of the Chernobyl SKALA computer system! This time, we'll look at a massive, nearly 300 kg Bulgarian ES-5061 hard disk drive and its accompanying portable test instrument, the TIDU-3P. This drive is the exact same type that was used in the DIIS system of the SKALA computer, as well as in the early "Shater" (Marquee) and "Finish" information systems of Chernobyl Reactor IV Sarcophagus.
    We acquired the TIDU-3P briefcase quite accidentally, and it brought us to the idea of connecting it to the actual drive to see if we could make them work together. This led us to a computer museum for our first attempt at exploring whether it was possible or not.
    What you will find in this episode:
    00:00 - Intro
    00:37 - Where were ES-5061 drives used?
    01:58 - Some news
    02:35 - A closer look...
    03:14 - Our initial examination of the equipment
    08:42 - TIDU-3P test instrument overview
    12:47 - What comes next?

      For someone like me who has worked on mainframes as a COBOL application programmer, this tech brings back memories. Still remember the old reel tape drives, then the compact square tapes that had to be mounted by operators, superceded by robotic tape silos, and then all of it was made redundant with virtual tape ie solid state memory.

    300KG, with wheels, so it is easy to move -- until you drop a wheel into the hole in the raised floor under the drive, where all the cables went down under the floor. Then get two friends so the three of you can get it level again and moving again. Been there, done that. You DO NOT want to do that with a vertical tape drive!

    A few years ago this same type of tester was up for sale here in Hungary on a local auction site. IIRC, the asking price was more than 100 000 HUF, which was rougly 400USD in 2018 (now it would be about $280 due to inflation).
    HEY! I just checked, and it is still up for sale from the same seller, but now for just 30 000HUF / $85. It is claimed to be brand new (NOS). I just asked him if he has documentation for it.
    EDIT: He answered, and unfortunately he has no documentation for it.

    At first sight, that looks a copy of a DEC removable hard disk: with RM03 (67MB)) or RM05 (256MB) packs even down to a DEC color scheme. In the west they would have been 70k$ back in the 1980s. The pull about 30A on spin up. If the heads crash, there is enough metal in the air that sometimes the next disk will crash too. As a summer student, I can tell you that they broke easily and the budget for maintaining them was enormous. Good times.

      Except for color, they are also nearly identical to IBM 360 era disk drives. Can't remember the model numbers anymore, but I think 2716 might have been one of them. I don't remember one pack crashing eating the adjacent packs much. In a good machine room with proper ventilation all the dust would have been pulled down under the floor. There were also air filters in the drive cabinet itself, and they would catch most all the dust. I do remember when long seeks would get these machines rocking, and one would start banging into the drive next to it, resulting in possible head crashes.

    As someone who worked with such computer disk drives in the 1970's I can say they need three phase power. And the disk in the drive is removable, weighs around 30 pounds, and only contains about 30 MB of data. The most important thing is to ensure the heads weren't damaged in transit otherwise that disk will squeal from contact as the data is destroyed.

    • @jvebarnes
      @jvebarnes 4 місяці тому +1

      @@ChernobylFamily In Australia the 3 phase was 410V and the 30MB was probably because of how they counted the Bytes here in the 1970's as in 1000 instead of 1024. Also we used 12 inch tape reels as storage and the disks were mainly for sorting and outputting the data to print. I wish you the best of luck with getting it running.

      @@ChernobylFamily The drive you're operating in this video certainly seems *very* well built, and made to last a literal lifetime. Better still - Because it's the disk-pack type - The media can be exchanged, so you just need the one unit plus storage for the media, as opposed to my collection of modern drives where every unit has its own controller, motor, head assembly etc... 👍
      Granted; A 300Kg unit is probably a bit too big for consumer applications (Good luck getting one of those up the stairwell in my UK block of flats, or the floor safely bearing the weight! 🤣) but the flipside is my devices definitely won't last a 30-50 year lifespan.

      The East German ROBOTRON R300 was mainly built as a copy of the IBM System360. My dad was a service technician and installed and serviced some of these machines in different countries. I remember he fixed ferrite memory ring arrays at home. I built my first amplifiers with scrap parts from decommissioned tape and hard drive machines, some early portable disks drives looked like this in the video. Punched paper cards for data, punched paper strips for programming later ½ inch tape and theses disks drives like a washing machine. I remember he told me every country of the eastern hemisphere had a specific field they had to cover. Bulgaria was responsible for these hard disk drives and heads of magnetic tape machines. But CzechSlovakia I believe to remember was also involved with tape drives. I played my first computer game on one of those machines, which was actually a star treck battle game where you would try to avoid getting caught by Klingon and then should shoot them down with photonic torpedoes. No real graphics, only characters used to make a graphical appearance. The other game was the board game GO.

    • @alanm8932
      @alanm8932 4 місяці тому +1

      100kB was just what they were aiming for in the early development stage. When they were delivered it said minimum 85kB. I remember typically it was 88kB. If you pressed the cartridge into the Microdrive while formatting, you might get 92kB but you would probably always need to hold it press it in to be able to use it like that, so not recommended!
      I expect pressing the cartridge in just pressed the tape harder against the tape head, creating more friction, so it took a bit longer for the tape loop to go around.

      Those are not ES, I am sure, this is something earlier than 70-s, element base and overall design is greatly different from ES standard. It is more a style of e. g. MIR or MINSK machines.
      ES boards (so called TEZ - standartized exchangeable elements) always have a unified form-factor of 140х150 mm and have either lamellae for corresponding type RPPM connector on a backplane, or in case of later 1060 and greater machines - SNP-135 connector (female on a TEZ and male on a backplane). They also must have an inscription ES-xxxx or EST-xxxx on them.
