Very cool, what's it from originally?
If anyone's wondering, this should help explain:

That is awesome.
Had some paper weight and art objects from old tech myself as well that I had to leave behind when emigrating to USA. IBM magnetic harddisk platter that was one platter from 5 in total from 20MB harddisk the size of a vinyl record (used a few as Frisbees as well). An old rotary disc mechanism from a phone distribution center, punch-cards used to program government systems, and a few other items, so looking at this makes me want those back again
The NASA Glenn Research Center is here in Cleveland, and have it on my list to visit, so wondering if they had any of these type of machines as well.

The digital computer we used for all our telemetry processing in those days was a Control Data model 924. Its main memory contained those same ferrite core doughnuts. The original machine contained 16K 24-bit words = 48K bytes. In 1967 we paid Control Data a cool million dollars (that's 1967 dollars!) to double the memory to 32K words. It took them about a week to complete the on-site conversion.

And now to think of the "power" that fits in the palm of an individual hand or an even smaller footprint. How did you manage to acquire it? ~~ or is that still classified intel

That was a bit before my time. I worked mostly with DEC PDP and VAX systems (Pipeline SCADA control)

Had some interesting talk with those maintaining them, and a lot of curse words were part of that conversation indeed.
And to think that only took care of a single digit.
They used bikes to ride through the building section that contained all those switches for a "city", whereas it was all replaced by a few ESS-5 racks.
Buying one from eBay is not the same to me as having the one I tore out myself, but it was nice to be reminded on them by your post on history.

In in relative terms. Hasn't actually been that long ago!
I wasnt even a twinkle in someone's eye at that time.
