Technology has come such a long way since I cut my teeth on "core memory" used in mid range computers that put the man on the moon.

128 bits (carbon do-nuts) on a 4"x 4" frame. Each bit was a carbon do-nut with a positive wire going in one direction to set it to "1" and another wire that passed the opposite direction to set it to "0". These layers were part of a bigger assembly that totaled 1280 bits of memory. The entire assembly took up 2 square feet of space with all the cooling fans attached.

Now you can get terabytes on a device the size of your finger.

Yes, I remember ‘core memory’........looked like a sieve .....................

Indeed:

That's almost $20,000 in today's money.

They were not carbon, they were ferrite.
