Hi,
Today I got a nice piece of memory history - USSR FERRYT MEMORY. What you think about it ? Maybe someone collect items like that ? Perfect visual condition and a bit heavy - about 4 kg.

Thank you for interest. I will post more pictures tomorrow. I rode some facts. These memories was produced in 60' and 70'. Poland produced them too. I heard that there was used much of platinum (platinium)  All productions of these memories was by hand - manufacturing. Capacity ? I can't find that information. I only found that 1 bit was on one core of ferryt.

The East German core memory board is made by KWH aka. Hescho aka. Tridelta. I love KWH. I have never seen a fab you will get out nearly nothing of the devices they made... There is not even a databook 
Nevertheless I know of which machine this board was taken... Sömtron ETR 220 A very early calculating machine... Shame to who wrecked it!!!

Nice piece of equipment. Teflon wires, 201 series hybrid RTL logic in IBM style aluminum cans. 201LB4 (also LB5 and LB7) are NAND gates with 270ns (not a typo) gate delay, 4V supply. 201NT2 is transistor array. Bigger metal cans marked MLZ 0,5-600 are delay lines. What amazes me is so late production date for hybrid logic - second half of 1983. I don't know what those big plastic modules are, maybe transformers.
It doesn't look like standard core memory, more like ROM.

It is good that person who extracted it isn't present on forum. He had that machine 10-20 years ago. It was wrecked to scrap yard ... only this memory alive.
