Me too! I've actually seen some similar videos in the classroom back in the '60s.

Flashback!  the clips on core memory tripped a trigger, the 1st CT I worked on with GE, a data General computer used core memory boards, I saved one, passed it on about 10yrs ago to a kid when he graduated from college with a computer science n programming degree.  He was so excited he wanted to figure out if he could incorporate it into a modern system :icon_biggrin:

I worked on a RADAR target processor up until about 2002. It was designed in the late '50s by Burroughs. It had a 2K x 52bit word core memory that was about a 10" cube. Very reliable. Also very sensitive to temperature changes. What a pain in the ass to align!

WOW you are good!  keeping antiques alive that long is no easy feat!  my core's were 4 boards (11X17) crammed so close you had to put x-ray film 'tween them just to remove/insert, 50pin ribbons bridging them, GE finally "upgraded" sometime in the late '90s.  The workmanship of all those hair fine copper wires threading 1/8'' ferrite beads was a thing of artistic beauty!
