40k Ferrite Memory Core

I've got one of those on my desk; see http://www.ece.mcgill.ca/~jthiem/IMG_1904.jpg I counted 32 planes (on the stack +1 separate), each with 64x64 (=4096) cores. Not visible on the picture between the black plates is the massive bunch of cables coming out. A 500GiB 3.5in drive for size comparison next to it. Note while I have those cores, I can't morally claim to own them. They were in a display case here in the ECE dept. at McGill (der Mouse might know more about it, he's been in this building longer than I have, albeit 3 floors down). The display case showed a bit of the evolution of storage... more useful when undergrads still came in here. The display case got dismantled at some point and the contents moved into a storage room - recently the storage room got cleared out to become part of a new lab and the contents were mostly to be junked - so I snagged the cores.
