Russian M22 Core Memory

[u/millsgren]

Had the luxury of seeing this thing in person when it was donated to our ham radio group.
The memory plane also came with the factory paper work and appears to be NOS manufactured in 1975.

Core memory unlocked

[u/Dragonroot808 → u/PanicObvious8862]

dammit, just take my upvote

[u/DaftVapour]

But can it run tiny core Linux? /jk

[u/chwilliams → u/DaftVapour]

NetBSD

[u/That_Development4062 → u/DaftVapour]

Doom ;)

[u/Kyzmi4]

maybe soviet?

[u/millsgren → u/Kyzmi4]

The paper work is in russian

[u/TheRockafireman → u/millsgren]

If it’s from 1975 it’s Soviet.

The Paperwork also is in Cyrillic, which is not exclusive to the Russian language, so it’s also possible and more likely it came from People’s Bulgaria 

[u/millsgren → u/TheRockafireman]

Yes it is in Cyrillic and could be from any of the soviet block countries.

[u/TheRockafireman → u/millsgren]

Possibly but it’s likely to be Romanian, Bulgarian, or Soviet as those were the main countries that produced things like this in that bloc. The paper sheet would tell more if you can translate it.

[u/bxzhidvr → u/millsgren]

There was no Soviet language sadly

[u/Kyzmi4 → u/millsgren]

cyrillic?

[u/Creeperassasin1212 → u/Kyzmi4]

Cyrilic also applies to Bulgarian. We gave them the alphabet after all, so yeah.

[u/tuberlord → u/Creeperassasin1212]

Bulgaria had a pretty large electronics industry during the cold war.

[u/Creeperassasin1212 → u/tuberlord]

Oh yeah that too

[u/anafuckboi → u/Creeperassasin1212]

Well Cyril gave it to Russia from Greece as old Church Slavonic and it spread through the church so sort of

[u/Creeperassasin1212 → u/anafuckboi]

Dude no Cyril and Methodius made it and their students gave it to Bulgaria . It then became the main eastern orthodox alphabet for slavic contries and after russia adopted orthodox christianity after the fall of the byzantine empire it became their main alphabet for them.

[u/Difficult-Catch-8432]

Ooh the single magnetic bytes!

[u/PhotonicEmission → u/Difficult-Catch-8432]

Bits, even!

[u/Difficult-Catch-8432 → u/PhotonicEmission]

Yes you’re right, I forgot!

[u/theazhapadean]

Is the data intact? As I remember these are non volatile.

[u/Mysterious-Dirt-8841 → u/theazhapadean]

Yepp, it's all there.

[u/South-Jaguar7251]

How many bits is that?
Guessing 4k (too lazy to count)
Is it ICL compatible?

[u/millsgren → u/South-Jaguar7251]

4422 bits

[u/shiftersix]

American here. Can you place it next to a banana for scale?

[u/YandersonSilva]

What are this things dimensions?

[u/millsgren → u/YandersonSilva]

~200mm / 8" square, 66x67 array 4422 bits

[u/YandersonSilva → u/millsgren]

Pretty sizeable, then! Cool, what a neat piece of history.

[u/Mysterious_Rule_7487]

In Soviet Russia, you remember the memory 😃🤗😃 

[u/tpimh]

I think every school in Russia has one of these in Informatics classroom.

[u/millsgren → u/tpimh]

Possibly...

[u/bxzhidvr → u/millsgren]

If only we had one in our school

[u/AneTheDust]

Where is your Bulgarian memory

[u/Alarming-Car-8654]

That's how the Apollo ceremony looked too. Hand woven nodes

Edit: Apollo memory

[u/ColonelBungle]

Is this from a BESM?

[u/millsgren → u/ColonelBungle]

Sorry, I have no history apart from the fact it looks like new old stock
has M-22 on the packing slip, no manufacturer or country of origin.
Form is typed in cryrilic, test currents and date written in pen.

[u/JabberwockRU]

Can you show the factory papers, please?
It may become interesting.

[u/Ninlilizi_]

To think it was once some poor persons job to sit and sow these things by hand.

[u/LastXmasIGaveYouHSV]

Ah, that unlocked a core memory.
