Magnetic core memory from 40 years ago

Please help us to find bad videos. Broken or unappropriated video content?
Here's a very interesting bit of technology from 40 years ago and it shows just how far we've come in just a few short decades with respect to computer memory.
Without the super-high density flash memory that modern SD and microSD cards offer, we'd never be able to build recording HD video cameras so I guess this is somewhat related to RC models :-)
