You know what’s crazy? 1.44 mb floppies are 25 years more advanced and new than the pictured 8 inch floppy with an incredible 80kb of data storage, unformatted
Also before more people say “if its broke don’t fix it”, brother every single system infrastructure is always being updated/adjusted constantly for optimization and security.
It may not be broke and need fixing, but all of the tech world strives for maximum profit margins therefore they optimize as much as possible.

I need to know this.
Meaning? A EMP will not destroy the vacuum tubes and that's something that integrated logic circuits Just aren't capable of to the same degree.
It's pretty popular and kind of scary that some of these vacuum tubes that are in use were manufactured in the 40s and 50s Some of them as old as the 1930s being new old stock Tubes.
The real problem with writing any virus software for these systems is that they are so completely individualized you would need to have the exact same hardware to be able to write any virus code for the hardware through the software..
And even if you did do something like that you still have no idea about how the system was set up Has that kind of stuff is in fact still heavily classified even years and years later.
Now it's not impossible, but the likelihood of that ever happening is almost slim to none has many of these systems simply just don't have any easy way to transfer any kind of data to these systems nor their storage media.
The reason why this antiquated technology is still being in years is that you can literally custom manufacture these parts in your 3D printer and they would be up and running unless then an hour many times the custom read heads are also simple wire wound devices that you could literally make by hand if you had to..
These systems were designed not only to last 20 years or for a certain predetermined amount of time but to be used a hundred years down the road and they would still exactly function and boot up and still work just like you install that yesterday.
electrolytic caps? absolutely not!
everything in these systems was designed to last as long as possible and of course you're going to have problems with such things as burnt out resistors but with the over 400% tolerance of some of these items out of the box it's rare to completely negligible.
Our power grid however, yeah that's a problem I'm not going to go into it any further but yeah that's a big issue
Edit: it’s like 3am and I thought this video was just about military nuclear systems LMAOOOO
Welcome back y2k !
And like, i used to work at repairing computers and laptops, and just seeing a lot of them with 32 bits was concerning
Even if like your windows xp is never connected to the internet. There are tons of others computers in the world managing sensitive info running on 2000 server or xp
If it is possible to put a job on microcontroller architecture developed in late 1970s, than do it. MCS-51 is beautiful and simple architecture, and i wish it is still used today as often as it is 20-30 years ago. Nowerdays other than some kitchen tech, industrial equipment. elevator control panels, LED screens, maybe some train/tram systems and intercom systems its hard to find MCS-51 alive and usable.
"I know a solution, lets make punchcards!"
- ends up trolling the entire world for like 2 decades
Never cut it.
Excellent video!
